Kayaking Tours in Koh Samui & Ang Thong Marine Park

Sea caves, limestone cliffs and hidden coves — where the paddling actually happens, what it costs, and the best dedicated kayak tours. Updated July 2026.

Where You Can (and Can't) Paddle

Ang Thong National Marine Park is one of Southeast Asia's premier sea-kayaking destinations — a protected archipelago of 42 limestone islands about 30 km northwest of Koh Samui. Virtually every day tour includes 45–90 minutes of guided kayaking on stable, beginner-friendly sit-on-top kayaks, with life jackets provided and no experience required.

Pоwered by GetYourGuide

One thing to know before you book: you cannot swim or kayak into the famous Emerald Lake (Talay Nai) on Koh Mae Ko — it's a strictly protected lagoon viewed from a platform after a stair climb. The kayaking itself happens on the open sea around the islands' cliffs, caves and coves, which is where the real payoff is.

🛶

What Makes It Special

Paddling beneath towering limestone cliffs, through rock arches and tunnels, past sea caves and into sheltered coves that larger tour boats simply can't reach.

Where the Kayaking Happens

Four spots come up again and again across operators.

🐄

Koh Wua Ta Lap

The park headquarters island. Kayak around the small adjacent islet and along the coral-fringed coast from Ao Kha.

💚

Koh Mae Ko

Paddle the coastline beneath limestone cliffs — this island also holds the Emerald Lake (viewing only, not kayakable).

🌉

Koh Sam Sao

Known for a natural stone arch bridge — the first few metres offshore are closed to boats, so kayaking is the intimate way to explore it.

🕳

Koh Tai Plao

A remote northern spot with rock overhangs, tunnels and a hidden lagoon — reached mainly on dedicated kayak-focused tours.

💚

The Emerald Lake — Confirmed View-Only

Talay Nai is a landlocked saltwater lake connected to the sea only through underground channels in the limestone. Visitors climb a staircase of roughly 240 steps to a viewpoint platform; swimming and kayaking inside the lake are banned to protect the fragile ecosystem, and drones aren't allowed either.

Worth Adding to Your Itinerary

Paddling pairs well with the rest of a Gulf of Thailand trip.

Beyond sea kayaking at Ang Thong Marine Park, from Koh Samui you can snorkel the clearer waters of Koh Tao and Koh Nang Yuan, meet the pigs on the Koh Madsum (Pig Island) and Koh Tan trip, hike to the Koh Wua Ta Lap viewpoint, or book a private boat charter for a fully custom paddling day. Live options are below.

Kayak Type & Who Can Paddle

The standard craft is a stable, two-person sit-on-top kayak — self-draining and easy to re-board. A single session typically runs 45–90 minutes, with dedicated kayak tours offering two sessions instead of one.

🥾

The Viewpoint Hikes, Not the Kayaking

The kayaking is easy for all levels — it's the viewpoint hikes (roughly 430 steep steps on Koh Wua Ta Lap) that are strenuous. Consider skipping those with very young children or limited mobility.

Ang Thong National Marine Park closes annually for monsoon-season restoration — no kayaking tours run.

Practical Tips

  • Bring reef-safe (mineral/zinc oxide) sunscreen — chemical sunscreens are banned park-wide, with fines up to 100,000 THB
  • Wear or pack water shoes for the Talay Nai viewpoint steps
  • A dry bag for phones and cameras (often provided by the operator)
  • Book a morning departure for the calmest paddling conditions
  • Tell your guide in advance if you're a nervous swimmer so they can stay close
    • 🧴

    2026 Update: Sunscreen Ban Enforcement

    Thailand's marine parks enforce a ban on oxybenzone, octinoxate, 4-MBC and butylparaben in sunscreens, with fines up to 100,000 THB. Rangers can inspect at park gates — bring mineral sunscreen or cover up with a rash guard.

    Common Question

    No. The Emerald Lake (Talay Nai) on Koh Mae Ko is a strictly protected, landlocked saltwater lagoon, and swimming or kayaking into it is prohibited to protect the fragile ecosystem. You view it from an elevated platform after a steep staircase climb of roughly 240 steps. The kayaking itself happens on the open sea around the park's limestone islands, cliffs, sea caves and coves — see our kayaking guide for the full route breakdown, or book a private charter for a fully custom paddling itinerary.
