The moment my feet sank into the powdery white sand of Koh Racha Yai, I knew I’d stumbled upon something special. The speedboat that had bounced me across the Andaman Sea for 30 minutes was now just a fading hum against the gentle lapping of turquoise waves. A few longtail boats bobbed offshore, their colorful ribbons dancing in the breeze against a backdrop of water so clear I could count the tiny fish darting between my ankles.

I’ll never forget my first glimpse of Patok Beach after that bumpy ride from Phuket—it was truly like stepping into a postcard I didn’t know existed. While tourists jostled for space on Patong’s crowded shores just 12 kilometers north, here I stood on an empty stretch of paradise, wondering how such tranquility could exist so close to Thailand’s busiest island.
This is what makes Koh Racha (also called Raya Island) such a treasure. While Phuket and Phi Phi have long stolen the spotlight in travel guides, this small island remains refreshingly authentic. Its pristine beaches, healthy coral gardens, and peaceful atmosphere offer a glimpse of what Thailand’s islands were like before mass tourism took hold.
In this guide, I’ll take you beyond the day-tripper experience to discover why Koh Racha deserves more than just a few hours of your time. From secret beaches only accessible by foot to underwater encounters that rival Thailand’s most famous dive sites, I’ll share the insights I’ve gathered over multiple visits to help you explore this island responsibly and meaningfully.
Having island-hopped across Thailand for nearly a decade now, I’ve developed a sense for what makes a destination truly special—and Koh Racha consistently tops my list of places worth protecting and experiencing. Let me show you why.
Getting to Know Koh Racha
Koh Racha actually refers to two islands—Koh Racha Yai (Big Racha) and Koh Racha Noi (Little Racha)—floating in the Andaman Sea about 12 kilometers south of Phuket. Racha Yai feels like Phuket’s quieter cousin, with enough infrastructure to make your stay comfortable without sacrificing its laid-back charm. Racha Noi, meanwhile, remains largely uninhabited—a wild, rugged beauty visited primarily by serious divers and fishing boats.
The islands were traditionally home to a small Muslim fishing community, whose simple way of life centered around the sea. You can still glimpse this heritage in the few remaining local homes near Bungalow Bay, where fishing boats are pulled up on shore and nets are mended in the shade. During a conversation with an elderly fisherman named Khun Chai on my second visit, he explained how the community has adapted to tourism while working to preserve their marine resources. “The fish feed my family,” he told me while untangling a net, “but the coral brings the visitors. We need both.”
Tourism has indeed transformed Racha Yai over the past twenty years, but unlike many Thai islands, development has been relatively restrained. The island lacks the concrete sprawl you’ll find on Phi Phi or Samui, with most resorts designed to blend with the natural environment. During Songkran (Thai New Year) celebrations in April, I watched as visitors respectfully joined locals in water-splashing festivities outside the small village shop—a heartening example of cultural exchange rather than displacement.
What keeps Koh Racha relatively hidden is somewhat counter-intuitive: its accessibility. At just 30 minutes by speedboat from Phuket, it’s marketed primarily as a day-trip destination. Most visitors arrive around 10 AM and depart by 3 PM, experiencing only a small slice of what the island offers. According to Khun Meow, who manages one of the beachfront restaurants, “The real Racha shows herself in the early morning and evening, when you can hear the island breathe.”
Data from the Tourism Authority of Thailand suggests that while Racha receives hundreds of day-trippers daily during high season, overnight guests number just a few dozen. This creates a unique rhythm—busy middays followed by tranquil evenings—that rewards those who choose to stay.
The Department of Marine and Coastal Resources has designated waters around both islands as protected areas, with ongoing coral rehabilitation projects showing promising results. During my most recent visit in January 2024, I participated in a reef monitoring session with Save Our Seas volunteers who confirmed that Racha’s marine ecosystem remains one of the healthiest in the region—a testament to both natural resilience and conservation efforts.
The Beaches of Koh Racha Yai
Patok Beach is the island’s main attraction and your likely first impression of Racha. This horseshoe-shaped bay welcomes you with powder-fine sand that squeaks underfoot and water in shades of blue that seem almost digitally enhanced. During midday, this beach buzzes with day-trippers snorkeling, swimming, and lounging under umbrellas set up by tour companies.
But stick around after 4 PM when the boats leave, and you’ll witness a magical transformation. The beach empties almost completely, the water calms to a glass-like finish, and you’ll understand why I’ve spent hours just sitting on this shore watching the sun paint the sky in watercolor swatches of pink and gold. One evening, I shared this sunset spectacle with just three other people and a playful dog belonging to one of the beachfront restaurants.

Siam Bay on the island’s east coast offers a completely different experience. A 15-minute walk from Patok along a paved path takes you to this longer, quieter stretch of coastline. The sand here is slightly coarser, the water deeper blue, and the vibe decidedly more relaxed. During my stay at Racha Island Resort, I would wake at sunrise to walk this beach completely alone, watching hornbills swoop between trees and small crabs create intricate patterns in the sand.
The restaurant at Baan Raya Resort, perched at Siam Bay’s northern end, became my favorite sunset spot—their fresh grilled fish and cold Singha beer perfectly complementing the peaceful views. As Khun Noi, the jovial waiter there, told me: “In Phuket, you pay for the sunset with noise. Here, you get it with silence.”
For true solitude, the smaller coves around Racha Yai’s coastline are worth seeking out. Lha Bay on the southern tip features a pebbly shore that feels like a secret only the corals know about. Getting there requires a 30-minute walk through the island’s interior, but I was rewarded with some of the best snorkeling I’ve experienced in Thailand—schools of parrotfish nibbling at healthy staghorn coral just meters from shore.
Ter Bay and Kon Kare Bay on the western side are similarly secluded, accessible via dirt paths that wind through the island’s modest hills. During my exploration of these beaches, I encountered only a handful of other adventurous souls. At Ter Bay, I spent a morning floating above coral gardens while completely alone—an increasingly rare experience in Thailand.
This privilege of enjoying unspoiled beaches comes with responsibility. I’ve witnessed the impact of careless tourism firsthand—during one visit, I helped a local guide explain to a tourist why standing on coral causes damage that takes decades to repair. The lesson seemed to stick, and it reminded me how important it is to tread lightly in these fragile environments.
Recent Tripadvisor reviews consistently rate Racha’s beaches among Phuket province’s finest, with many highlighting their cleanliness compared to mainland shores. As one reviewer aptly noted, “It’s like Phuket’s beaches 30 years ago.” Having spent considerable time on both islands, I can confirm this sentiment isn’t mere nostalgia—Racha’s shores genuinely offer what many Thai beaches have lost to overdevelopment.
Adventures in and Under the Water
Koh Racha’s reputation among divers is well-earned. The visibility here regularly exceeds 20 meters, revealing underwater landscapes that rival marine protected areas elsewhere in Thailand. My first dive at Racha Yai felt like floating through an aquarium—leopard sharks resting on sandy patches, garden eels swaying like grass in the current, and shoals of yellow snappers moving in mesmerizing unison.
For beginners, Racha Yai offers ideal conditions to learn. The bay directly in front of The Racha resort features a gentle slope with depths suitable for introductory dives. It was here that I watched a friend take her first underwater breaths during a Discover Scuba session, her wide eyes behind the mask telling me everything about the wonder unfolding around her.
More experienced divers should venture to Racha Noi, where stronger currents reward you with larger pelagic sightings. During a day trip with Oceanic Dive Center, we encountered a manta ray gliding effortlessly through the blue—a moment of underwater magic that’s burned into my memory. Our divemaster, Khun Arm, explained that while such sightings aren’t guaranteed, they’re common enough to make Racha Noi a regular stop for serious divers based in Phuket.
What impressed me most was the health of the coral, particularly at sites like Lucy’s Reef and Staghorn Reef. According to marine biologists working with the Department of Marine Resources, Racha’s reefs have shown remarkable resilience despite rising sea temperatures that have bleached coral elsewhere in the Andaman.
For non-divers, snorkeling offers almost equally impressive experiences. The northern end of Patok Beach features rocky outcrops teeming with reef fish just meters from shore. I’ve snorkeled this area numerous times, consistently spotting pufferfish, moray eels, and once even a small blacktip reef shark.
Various operators offer snorkeling tours around the island, but I’d recommend organizing your own exploration with rental equipment from shops near the pier (about 200 THB for a day). This allows you to avoid the busiest spots and snorkel at your own pace. Just remember to bring a reusable water bottle—I learned this lesson the hard way after becoming dehydrated during an enthusiastic three-hour snorkel session.

Beyond the water, Racha offers enough activities to fill several days. Kayaks are available for rent (around 300 THB per hour) and provide a perfect way to explore the coastline’s hidden nooks. During my paddle around the northwestern shore, I discovered a tiny beach accessible only by water, where I spent a blissful hour completely alone.
For those seeking more adrenaline, ATV tours traverse the island’s interior hills, though I personally prefer exploring these paths on foot to minimize environmental impact. The island’s highest point offers panoramic views across both Racha islands and all the way back to Phuket—worth the sweaty 40-minute hike from Patok Beach.
When selecting activity providers, I strongly recommend choosing operators who demonstrate environmental awareness. Dive shops adhering to PADI’s Green Star program (like Racha Dive Center) follow sustainable practices, while some snorkel tour operators participate in beach cleanups and coral monitoring. As a visitor, asking questions about conservation practices before booking sends an important message about what tourists value.
Where to Stay and Eat
Accommodation on Koh Racha Yai spans the spectrum from luxury to rustic simplicity, though options are limited compared to larger islands—which is precisely part of its charm. At the high end, The Racha offers polished villas with private pools and five-star amenities. I splurged on a stay here for my birthday one year and found the experience worth every baht, particularly for their commitment to sustainability (solar power, water recycling) alongside luxury.
Mid-range options include Ban Raya Resort on Siam Bay, where whitewashed bungalows are scattered among tropical gardens. The atmosphere here is more laid-back, with a family-friendly vibe that appeals to those seeking comfort without ostentation. During my three-night stay, I appreciated the friendliness of the staff who remembered my name and coffee preference by the second morning.
For budget travelers, Bungalow Raya near the main pier offers simple rooms with fans rather than air conditioning. While basic, their beachfront location can’t be beaten—I loved the low-key authenticity of hearing the waves while falling asleep in their wooden bungalows. As with much of Thailand, accommodations should be booked well in advance during high season (November-March), when the limited rooms fill quickly.
Dining options cluster mainly around Patok Beach, with a handful of restaurants serving Thai classics and fresh seafood. Ban Raya Restaurant became my dinner go-to for their exceptional tom yum talay (spicy seafood soup) and whole grilled fish with lime and chili. The owner, Khun Pla, once showed me how they select fish directly from local fishermen each morning—an education in freshness I still remember when I’m disappointed by seafood elsewhere.
For simpler meals, the family-run Raya Father Restaurant near the main pier serves generous portions at reasonable prices. Their massaman curry became my comfort food during an unexpected rainy afternoon. When I complimented the rich flavor, the cook—a grandmother with sparkling eyes—gestured me into her tiny kitchen to show me how she pounds the curry paste by hand rather than using commercial products.
It’s worth noting that food prices run about 20-30% higher than in Phuket due to transport costs, with most ingredients brought from the mainland. A typical Thai meal costs 150-300 THB, while seafood dishes can reach 400-600 THB depending on market prices and catch availability.
One practical tip I learned the hard way: bring sufficient cash, as there are no ATMs on the island. While larger resorts accept credit cards, smaller establishments operate on cash only. When I ran short during my first visit, the restaurant owner kindly let me settle my bill via bank transfer once I returned to Phuket—a trust-based system that speaks to the community’s character.
Unlike Phuket with its buzzing nightlife, evenings on Racha are delightfully tranquil. A few beach bars offer cocktails and beers with acoustic music, but most activity winds down by 10 PM. For me, this quiet atmosphere became one of the island’s greatest luxuries—sitting on my porch watching fireflies while listening to distant waves instead of thumping bass.
Planning Your Trip
Getting to Koh Racha requires first reaching Phuket, then taking a boat from either Chalong Pier or Rawai Beach on Phuket’s southern coast. Speedboats make the crossing in about 30 minutes (600-1000 THB one-way), while slower longtail boats take 1-2 hours (usually around 600 THB but requiring enough passengers to fill the boat).

I’ve found the most hassle-free approach is booking transfers through your accommodation, as they’ll coordinate with boat operators and often provide pier transfers on both ends. For independent travelers, companies like Racha Ferry and Tigerline Marine operate regular services, with tickets available online or through agents in Phuket.
The ideal time to visit falls between November and April during the dry season, when seas are calm and visibility for snorkeling and diving is at its best. December through February offers the most reliable weather, though these months also bring the highest visitor numbers and accommodation rates.
May through October brings the monsoon season, with increased rainfall and choppier seas that occasionally cause boat cancellations. However, visiting during these shoulder months can mean significantly lower prices and fewer crowds. During a June visit, I experienced morning showers followed by gloriously sunny afternoons with beaches almost to myself—though boat crossings were admittedly rough.
Packing thoughtfully enhances your Racha experience. Beyond the usual tropical island essentials (swimwear, light clothing, hat), I recommend bringing:
- Reef-safe sunscreen (oxybenzone-free) to protect both your skin and the coral
- A rashguard or swim shirt for snorkeling (sunburned backs are the most common tourist injury)
- Water shoes for exploring rockier beaches and protecting feet from occasional sea urchins
- A good book and downloaded entertainment (Wi-Fi exists but can be spotty)
- Motion sickness medication for the boat journey (especially during monsoon season)
- A small first aid kit including antihistamines and hydrocortisone cream (for minor stings or insect bites)
I always pack a sarong as well—it serves as a beach blanket, sun protection, makeshift bag for beach finds, and even dressed-up evening wear when dining at nicer restaurants.
For budget-conscious travelers, consider visiting midweek during shoulder season (May or November), when accommodation rates drop by 30-40%. Joining group snorkeling tours rather than hiring private longtails saves considerably, as does bringing some snacks and drinks from Phuket (though support local businesses where possible).
A typical budget breakdown based on my experiences:
- Budget accommodation: 1,200-2,500 THB per night
- Mid-range resort: 3,000-6,000 THB per night
- Luxury villa: 8,000+ THB per night
- Local meal: 150-300 THB
- Seafood dinner: 400-600 THB
- Speedboat transfer (one-way): 600-1,000 THB
- Snorkel rental: 200 THB/day
- Guided snorkel tour: 800-1,200 THB
- Diving: 3,000-3,500 THB for two dives with equipment
These prices reflect my visits through early 2024—I’d recommend checking current rates as Thailand’s tourism recovery has brought fluctuating prices across the region.
Why Koh Racha Stays in Your Heart
Koh Racha isn’t just a destination—it’s a feeling of peace you carry home long after sand has been shaken from your shoes. The island’s true magic lies in the moments between scheduled activities: watching hermit crabs race across the beach at dawn, floating on your back in bath-warm water as clouds drift overhead, or sitting in comfortable silence with a cold drink as stars emerge over the Andaman.
During my last evening on Racha, I walked to the southern end of Patok Beach where a handful of locals and overnight guests had gathered informally to watch the sunset. No one spoke much—we didn’t need to. As the sky transformed from blue to gold to deep purple, I realized what makes this island so special isn’t any single attraction but rather how it slows you down enough to notice the beauty that exists everywhere.
A fisherman I befriended during that sunset, who introduced himself simply as Chai, summarized it perfectly: “Racha doesn’t change you,” he said, nodding toward the horizon. “It reminds you who you already are when no one is watching.”
As Thailand’s more famous destinations grapple with overtourism, places like Koh Racha become increasingly precious. By visiting mindfully—supporting local businesses, respecting marine life, and embracing the island’s natural rhythm—we help preserve what makes it special. The greatest compliment we can pay is to leave it exactly as beautiful as we found it.
If Koh Racha has captured your interest, I’d love to hear your questions or experiences in the comments. This small island has given me so many perfect moments; my hope in sharing it is that you might discover your own.
