Last month, I stepped off the BTS at Siam Station and Bangkok’s energy hit me like a wave—street food sizzling in woks, tuk-tuks zooming past, and the afternoon heat making my shirt stick to my back. But beneath the gleaming Siam Paragon mall, a different world awaited—one where the chaos of the city faded into serene blue.

I’ve visited aquariums from Sydney to San Francisco, but there’s something magical about finding 30,000 sea creatures swimming peacefully beneath one of Asia’s busiest shopping districts. SEA LIFE Bangkok Ocean World isn’t just Southeast Asia’s largest aquarium; it’s a cool, immersive escape from the tropical heat above.
My friend Mai had recommended it during my last trip, but I ran out of time. “Next visit, don’t miss it,” she insisted. “The shark tunnel alone is worth it.” She wasn’t wrong—but I’m getting ahead of myself. Join me as I dive into Bangkok’s underwater gem, where I came face-to-face with everything from playful otters to prehistoric-looking sharks, and discover my tips for making your visit splash-worthy.
Getting There: Finding Your Way to the Ocean
The journey to SEA LIFE is straightforward, especially if you’re already planning to shop at Siam Paragon (991 Rama I Road). The aquarium is tucked away in the basement level B1 and B2, and while I nearly walked past the entrance (I was distracted by the sweet smell of fresh crepes from a nearby kiosk), the large sea life signage eventually caught my eye.
For transport, you’ve got options:
- BTS Skytrain to Siam Station (my pick—cheap, cool, and no traffic stress)
- Taxi (use the meter!)
- Tuk-tuk (negotiate beforehand)
If you’re visiting with seniors or pushing strollers, don’t worry—elevators throughout Siam Paragon make access a breeze.
According to SEA LIFE’s website, the aquarium operates from 10:00 AM to 8:00 PM daily, with the last entry at 7:00 PM. I arrived around 10:30 AM on a Tuesday, and while there were school groups trickling in, it wasn’t overwhelming. Weekends are definitely busier, based on the crowd photos I scrolled through while planning.
My top tip? Hit the aquarium early or after 3:00 PM to avoid the midday crush of tour groups. Trust me, having that ocean tunnel to yourself makes all the difference.
The Aquarium Experience: Seven Zones of Wonder
Walking in, I was handed a colorful map outlining seven distinct zones. Two hours should cover everything, but I ended up spending closer to three, partly because I couldn’t tear myself away from the hypnotic jellyfish display.
Weird and Wonderful
The journey begins in the Weird and Wonderful zone, where Mother Nature shows off her most creative designs. I stood transfixed before a tank of leafy sea dragons—they looked like they’d swum straight out of a fantasy novel, their delicate appendages waving like underwater foliage.
“They’re related to seahorses,” a staff member named Pim told me, pointing out how they blend with seaweed for protection. “They’re masters of disguise.”
Nearby, the giant Pacific octopus was having a lazy day, tucked into a corner of its tank. “Come back in the afternoon,” Pim suggested. “That’s when he gets active.” The enormous Japanese spider crabs in the next tank made up for it, their legs spanning wider than I am tall. Having seen similar creatures at Osaka Aquarium last year, I was still struck by their alien-like appearance.
Open Ocean
Nothing prepares you for the Open Ocean tunnel—a 270-degree glass walkway where sharks, rays, and schools of fish glide above and beside you. I spent a good twenty minutes here, watching as a leopard shark cruised lazily overhead, its spotted pattern casting dappled shadows.
“It feels like diving without getting wet,” I overheard a mother tell her wide-eyed toddler, and she wasn’t wrong. The tank holds 1.6 million liters of water according to the display sign, making it one of the largest in Southeast Asia.
The slow-moving walkway can be crowded during peak hours, but I waited for a small gap between groups and had a magical few minutes alone in the tunnel. Worth. Every. Second.
Deep Reef
Emerging from the tunnel, the Deep Reef zone surrounds you with the vibrant colors of coral ecosystems. Touch screens designed for kids offered information about reef conservation, but I noticed adults (myself included) spending just as much time tapping through them.

The clownfish display brought back memories of snorkeling in the Philippines—these little orange-striped fish darting in and out of swaying anemones, completely unfazed by the giant humans watching them. A group of school kids pressed their faces against the glass, pointing and giggling each time a clownfish peeked out.
The tank of venomous lionfish, with their striped bodies and feathery fins, was both beautiful and intimidating. The information panel didn’t sugar-coat the damage these invasive predators have caused in the Atlantic, which I appreciated.
Rainforest
The Rainforest zone offers a refreshing change of pace, shifting from saltwater to freshwater habitats. The star attractions here are undoubtedly the Asian small-clawed otters, who were in full energy mode during my visit. I watched them twist and dive through the water, occasionally popping out onto rocks to groom themselves.
“They’re fed five times a day,” explained a keeper who was preparing their lunch. “Otherwise, they’d get bored.”
Giant arapaima fish—some of the largest freshwater fish in the world—cruised slowly in adjacent tanks. Their size was impressive, but honestly, I couldn’t look away from those playful otters long enough to fully appreciate them.
The rainforest zone’s humid atmosphere and recorded bird sounds created an immersive jungle vibe that contrasted nicely with the cooler ocean exhibits.
Rocky Shore
The penguin habitat in the Rocky Shore zone was busy with families, and for good reason. The Penguin Ice Playground houses a colony of gentoo penguins in a climate-controlled environment that mimics their natural habitat.
I timed my visit perfectly for the 1:00 PM feeding, where a keeper shared facts about these birds while tossing them fish. Did you know gentoo penguins can swim up to 36 km/h? That’s faster than I can ride a bike!
The penguins seemed to have distinct personalities—one particularly bold individual kept swimming right up to the viewing glass, eyeing visitors curiously. Kids squealed with delight, and I couldn’t help but smile too.
Living Ocean
The interactive touch pools in the Living Ocean section invited visitors to gently touch starfish, bamboo sharks, and sea cucumbers. I rolled up my sleeve and ran a finger across a starfish—it felt like wet sandpaper, firm yet slightly yielding.
“Don’t pick them up, just use two fingers to touch,” reminded a staff member who watched visitors like a hawk. I appreciated their vigilance in protecting these creatures.
The sea cucumber was surprisingly soft, nothing like I expected. A little girl next to me quickly pulled her hand back with a “ewww!” that made everyone laugh.
This zone connects education with experience beautifully, though patience is required during busy periods when children (understandably) want to linger at the touch pools.
Sea Jellies
The final zone was perhaps my favorite—a darkened room where illuminated tanks showcased different species of jellies. Their translucent bodies pulsed rhythmically like living lanterns. I was mesmerized by moon jellies floating in blue light, their simple disc shapes hiding complex life cycles explained on nearby panels.
Currently, this area features an art collaboration with Mackcha (running through June 2025), adding colorful illustrations and interactive elements that blend science with whimsy. Information signs explained how jellies thrive despite having no brain, heart, or bones—nature’s ultimate minimalists.

I lost track of time here, watching these graceful creatures drift in currents. It was meditative, almost hypnotic.
Activities and Add-Ons: Beyond the Tanks
SEA LIFE Bangkok offers several add-on experiences beyond standard admission. While they bump up the cost, some are worth considering:
Glass Bottom Boat
The Glass Bottom Boat ride (300 THB) takes you across the surface of the main tank in a small vessel with transparent flooring. It’s fun but brief—lasting only about 10 minutes. Children from age 2 can participate, making it popular for families.
“I can see the shark!” a young boy shouted during my ride, pointing down as a blacktip reef shark glided beneath us.
Honestly? If your budget is tight, you can skip this and still have a fulfilling experience. The underwater tunnel offers similar views with more time to enjoy them.
4D Cinema
The 4D Cinema (250 THB) was showing a SpongeBob SquarePants feature during my visit. It’s a short film enhanced with sensory effects like water sprays and seat movements. My inner kid loved it, but the outer adult recognized it’s primarily designed for children. Still, hearing kids squeal with delight when water misted from the ceiling made it worth the extra baht.
Shark Dive
For the adventurous (and certified divers), SEA LIFE offers Shark Dive experiences (6,500 THB). I didn’t try this myself, but I watched a group of teenage divers emerge from their session, buzzing with excitement.
“Mom, I high-fived a shark!” one exclaimed, clearly exaggerating but riding the adrenaline high. For diving enthusiasts, this could be a highlight of your Bangkok trip.
Feeding Shows
The daily feeding schedule includes penguin feedings (1:00 PM and 4:00 PM) and shark feedings (11:30 AM and 3:30 PM). These don’t cost extra but require timing your visit strategically. The otter feeding was surprisingly entertaining—these little guys have personality for days and performed tricks that had everyone clapping.
I’d recommend building your visit around at least one feeding time. The staff commentary adds educational value, and the animals are most active during these sessions.
Behind-the-Scenes Tour
The Behind-the-Scenes Tour (950 THB) offers a peek at the nursery areas and water filtration systems. A friend who took this during a previous visit said it was fascinating for science-minded visitors but might bore younger children.
Mackcha’s Ocean Art Exhibition
The limited-time collaboration with artist Mackcha (through June 2025) adds colorful art installations throughout the jellyfish zone. These Instagram-worthy backdrops blend sea life education with pop art aesthetics. No extra cost for this—it’s included with standard admission.
A money-saving tip: booking through Klook or other online platforms often scores you 15-20% off combined experiences. I saved about 400 THB by booking my ticket plus Glass Bottom Boat online rather than at the counter.
Practical Tips for Visitors: Maximizing Your Underwater Adventure
Tickets and Pricing
Standard admission costs around 1,090 THB for adults and 890 THB for children (3-11 years) at the door, but online prices through SEA LIFE’s website or Klook can drop to 700-900 THB. There is dual pricing—Thai nationals pay significantly less—which is common at tourist attractions throughout the country.
Family packages and combined tickets with Madame Tussauds (located in the same building) offer better value if you’re planning to visit both attractions.

Timing Your Visit
As mentioned earlier, early morning (10:00-11:30 AM) or late afternoon (after 3:00 PM) offer the calmest experience. I arrived at opening time and had the ocean tunnel almost entirely to myself around 11:00 AM—magical!
School holidays and weekends bring bigger crowds, particularly local school groups during weekday mornings. If traveling with children, prepare them for potentially crowded touch pools that might require patience.
Family-Friendly Features
SEA LIFE Bangkok is exceptionally kid-friendly with:
- Low viewing windows at child height
- Interactive educational games
- Step stools at taller exhibits
- Changing tables in restrooms
- Stroller accessibility throughout
Parents of toddlers should note that the dim lighting in some areas could make keeping track of energetic little ones challenging. The penguin zone and touch pools were clear favorites among the families I observed.
Amenities
Restrooms are clean and available throughout the aquarium. A small cafeteria near the exit offers basic snacks and drinks, but the real food destination is upstairs in Siam Paragon’s impressive food hall, featuring everything from budget Thai dishes to international cuisine.
Photography is permitted without flash, and the lighting is optimized for decent smartphone shots in most areas. The jellyfish zone is particularly photogenic.
Conservation Efforts
Throughout my visit, I noticed SEA LIFE’s emphasis on marine conservation, particularly their work with endangered species breeding programs. Interactive displays explain threats like plastic pollution, overfishing, and climate change in kid-friendly terms without being preachy.
A breeding program for bamboo sharks demonstrates their commitment to conservation beyond simply displaying animals.
Recent Updates
Following recent seismic activity in the region, SEA LIFE conducted thorough safety checks in March 2025. According to staff, they’re offering refunds for tickets purchased during a three-day closure period (contact by April 30, 2025, with proof of purchase).
Reflections: Why SEA LIFE Bangkok Stands Out
I’ve visited aquariums worldwide, from Georgia Aquarium’s massive whale shark exhibits to Sydney’s harbor-side attractions, but SEA LIFE Bangkok offers something special—an underwater sanctuary in the heart of one of Asia’s most energetic cities.
What struck me most wasn’t any single exhibit but the contrast: escalating from Siam Paragon’s luxury shops down to this peaceful blue world feels like discovering a secret dimension beneath the city’s surface.
The educational aspects impressed me too. Watching Thai schoolchildren learn about ocean conservation, their eyes wide with wonder as they pressed hands against the glass, gave me hope for future generations of environmental stewards.
While not the world’s largest aquarium, SEA LIFE Bangkok efficiently uses its space to create immersive environments that appeal to marine enthusiasts of all ages. It’s the perfect cool break during Bangkok’s heat, offering 2-3 hours of exploration that complements other city activities.
Plan Your Underwater Adventure
SEA LIFE Bangkok Ocean World offers a diverse marine experience that stands out even in a city full of attractions. From the mesmerizing jellyfish displays to the interactive touch pools and 270-degree ocean tunnel, there’s something here for everyone.
Book your tickets early online for the best prices, check the feeding schedule to plan your route, and bring your curiosity—the staff clearly love answering questions and sharing marine facts with interested visitors.
I left smiling, already mentally planning which friends I’d bring on my next visit. In a city known for its temples, markets, and street food, this underwater adventure offers a refreshing change of pace that might just become the surprising highlight of your Bangkok trip.
