Kayaking through the lagoons and sea caves of Ang Thong Marine Park is one of the most memorable experiences you can have in Koh Samui. Paddling between towering limestone cliffs, through hidden caves, and across emerald-green lagoons offers a perspective of the park you can't get from a speedboat. Here's everything you need to know about kayaking at Ang Thong, from what to expect to which spots you'll explore.
Kayaking at Ang Thong: The Basics
Most full-day Ang Thong Marine Park tours include kayaking as part of the itinerary. At Samui Authentic, our 7.5-hour tour (4,400 THB per adult) includes 45-60 minutes of kayaking with all equipment, life jackets, and a guide accompanying the group.
Kayaks are typically launched from the main beach at Koh Wua Ta Lap (the largest island and park headquarters) or from Koh Mae Ko (home of the Emerald Lagoon). The routes take you through sheltered lagoons, along dramatic coastlines, and into sea caves accessible only by kayak.
No Experience Needed
The waters inside Ang Thong are calm and protected. Even complete beginners can kayak comfortably here. Guides provide a brief instruction session before you set off, covering basic paddle technique and safety.
Where You'll Kayak in Ang Thong
1. Koh Wua Ta Lap — The Main Kayaking Area
Koh Wua Ta Lap is the largest island in the archipelago and where most tours spend the majority of time. The kayaking route here follows the coastline, paddling past limestone cliffs, through narrow channels between rocks, and into shallow lagoons.
What you'll see: Towering karst formations rising from the water, small hidden beaches, coral visible through the clear water, and often schools of fish swimming beneath your kayak. The route is approximately 2-3 km and takes 45-60 minutes at a relaxed pace.
2. Koh Mae Ko — Kayaking Near the Emerald Lagoon
Koh Mae Ko is famous for the Emerald Lagoon (Talay Nai), a stunning landlocked saltwater lake. While you can't kayak inside the lagoon itself, some tours include kayaking around the island's coastline, which features sea caves and channels.
What you'll see: Sea caves with stalactites, narrow passages between cliffs, and incredibly clear turquoise water. This route is more adventurous and includes paddling through low-clearance caves (only accessible at mid to low tide).
3. Eastern Islands — Mangrove Channels
Some private tours or extended itineraries include kayaking through mangrove channels on the eastern side of the park. These sheltered waterways are home to diverse birdlife and juvenile fish that use the mangroves as nurseries.
What you'll see: Mangrove trees with exposed roots, herons and kingfishers, and a completely different ecosystem from the open-water areas. It's quieter and more peaceful than the main kayaking routes.
Difficulty Level & Fitness Requirements
Kayaking at Ang Thong is suitable for all fitness levels. The routes are designed for beginners, and the water is calm with no strong currents or waves. You paddle at your own pace, and guides adjust the route based on the group's ability.
Who Can Kayak at Ang Thong?
- Beginners — No prior kayaking experience is needed. Guides provide instruction and stay close throughout.
- Children — Kids as young as 4-5 can kayak in a double kayak with an adult. Life jackets are provided in all sizes.
- Seniors — The gentle pace and calm waters make it accessible for older travelers with reasonable mobility.
- Non-swimmers — You don't need to know how to swim. Life jackets are mandatory for all participants, and you're never in deep water alone.
Physical Effort
Expect a moderate workout for your arms and shoulders, but nothing strenuous. If you can walk comfortably for 30 minutes, you can handle the kayaking. The biggest physical challenge is actually the 500-step hike to the viewpoint, not the kayaking.
Equipment & What's Provided
All kayaking equipment is included in Ang Thong Marine Park tours. Here's what you'll use:
- Sit-on-top kayaks — Stable, easy-to-use kayaks (not the enclosed sit-inside type). Available as singles or doubles.
- Paddles — Lightweight double-bladed paddles adjusted to your height.
- Life jackets — Mandatory for all participants, provided in all sizes from children to adults.
- Dry bags — Small waterproof bags for phones, cameras, and valuables (limited supply — ask your guide).
What to bring: Waterproof phone case, sunglasses with a retainer strap, reef-safe sunscreen, and a hat that won't blow off. Leave valuables on the boat if possible.

Book Ang Thong TourBest Conditions & Timing
Best Season for Kayaking
December to March offers the calmest seas and clearest weather. This is peak season for Ang Thong tours. The park is closed annually from November 1 to mid-December due to monsoon conditions.
April to October is still good for kayaking, though afternoon thunderstorms are possible. Morning tours are more reliable during this period.
Tide Considerations
Some sea caves and narrow passages are only accessible at mid to low tide. High tide can make cave entrances too shallow to paddle through safely. Tour operators plan kayaking times around tide schedules to maximize access to interesting routes.
Kayaking Tips for Ang Thong
- Start slow — Find your rhythm in the first 5-10 minutes. Don't paddle too aggressively at the start or you'll tire quickly.
- Use your core — Rotate your torso when paddling, not just your arms. This technique is less tiring and more efficient.
- Stay hydrated — Bring water or ask your guide. Kayaking in the sun is deceptively tiring.
- Secure your belongings — Dry bags aren't always 100% waterproof. Double-bag electronics or leave them on the boat.
- Apply sunscreen early — Your arms, legs, and the tops of your feet (if wearing sandals) will be exposed to direct sun.
- Listen to your guide — They'll point out marine life, caves, and photo opportunities. Stay within sight of the group.
- Take breaks — If you're in a double kayak, communicate with your partner. It's okay to stop paddling and drift for a moment.
Safety & What If I Tip Over?
Tipping over is extremely rare in Ang Thong. The kayaks used are wide, stable sit-on-top models designed for calm water. The water is also warm (26-28°C year-round), so even if you do end up in the water, it's not uncomfortable.
If you do tip: Simply climb back onto the kayak from the side (guides will demonstrate this before you start) or hold onto the kayak and wait for the guide to assist. You're wearing a life jacket, so you'll float comfortably.
Safety measures: All tours have safety kayaks with guides positioned at the front and rear of the group. A support boat stays nearby. Mobile phone signal is limited but emergency radios are carried.
