Pattaya: Underwater Sea Walking Experience — An Honest Review
When it comes to fun things to do in Pattaya, the Underwater Sea Walking experience is often recommended for those who want a different perspective on Thailand’s marine beauty. While it promises an accessible adventure suitable for all ages, it also comes with some mixed reviews that are worth considering before booking.
What we love about this experience is the ease of participation—no swimming skills needed, making it perfect for families or less confident swimmers. The full-day Koh Larn excursion offers a chance to explore a scenic island with a variety of activities, and the speedboat transport makes getting around quick and comfortable.

What to Expect from the Pattaya Underwater Sea Walking Tour

This experience is designed to be straightforward, enjoyable, and accessible, whether you’re a seasoned adventurer or a curious beginner. The core highlight is the sea walking activity, which allows you to walk comfortably along the seabed, observing marine life without needing to swim or snorkel. The experience is open to anyone aged 8 and above, making it family-friendly, but it’s important to note that safety instructions, especially in English, may sometimes be brief, so paying close attention is wise.
The tour’s full-day itinerary begins with an early pickup (be sure your contact info is correct and reachable via WhatsApp, Line, or Tel, as staff contact you the day before). Once on board the speedboat, you’ll be whisked away to Koh Larn, a beloved island known for its pristine beaches and clear waters.

Koh Larn and Surroundings
Koh Larn forms the main highlight of the trip. Its scenic beaches and calm waters create a perfect backdrop for relaxation and exploration. The tour typically includes free time on the island—where you can lounge on the sand, snap photos, or explore other water activities (these are optional and extra). The snorkeling session at Koh Sak is specifically tailored for marine exploration, although some reviews note that marine life sightings can be limited, especially when the water gets stirred up by other boats or activities.
The Underwater Sea Walking Experience
The main draw for many is the sea walking activity at Manta Marina. Here, participants are fitted with a helmet that supplies a steady air flow, allowing for hands-free walking on the ocean floor. The setup is designed to be safe and easy—no diving experience or swimming ability required.
However, different reviewers report varying experiences. Some found the timing well-organized and appreciated the friendly guides, such as Miyu, who was praised for being “kind and helpful.” Others, like Laia from Germany, felt that safety instructions in English were lacking, and they weren’t fully informed about air pressure management or where the best spots for marine viewing are. She also mentioned waiting a long while while others fed the fish or took photos, which cut into her underwater experience.
Snorkeling and Additional Activities
After the sea walking, your day continues with snorkeling at Koh Sak. While it sounds idyllic, some reviews reveal that marine visibility was not as vibrant as expected, and the snorkeling spot may be too deep for some to see much marine life clearly. It’s a shared tour, so there might be some waiting during activities, especially if the group is large or busy with other water sports.
The tour also offers the chance to add activities like parasailing or jet skiing—perfect if you’re craving a bit of adrenaline. These are extra charges, but they can significantly elevate your day with high-flying views or splashy fun. One traveler mentioned that the guide was very helpful, making the experience smooth and enjoyable, even when waiting for their turn on the additional water sports.

The speedboat transfer is highlighted as a major plus. It’s quick and comfortable, minimizing the time spent in transit and maximizing your time on the water and island. The full-day tour lasts about 6 hours, starting in the morning and wrapping up in the early afternoon.
Since this is a join tour, expect to be part of a group, which can mean some waiting or shared experiences. The timed schedule is designed to be efficient, but it’s worth noting that some activities might feel rushed during busy days.
The tour’s small group size generally helps keep the experience intimate, but it varies based on demand. The English and Thai-speaking guides are knowledgeable and friendly, which adds a lot to the overall vibe.
Pricing and Value

At its core, the tour offers a combination of several activities—sea walking, island exploration, snorkeling, and optional water sports—which makes it relatively good value, especially considering the included transportation and guides.
