The morning boat cuts through blue Gulf water as Koh Samui recedes behind you and limestone islets rise like small fortresses ahead. Salt spray cools the face; the guide calls out landmarks and you ready your mask. By mid-morning the longtail transfers you into the archipelago’s quieter coves where paddles push you along sheer cliffs toward a hidden saltwater lagoon.

The morning boat cuts through blue Gulf water as Koh Samui recedes behind you and limestone islets rise like small fortresses ahead.

Ang Thong National Marine Park is a compact cluster of 42 islands created from uplifted limestone and coral platforms. Declared a marine park in the early 1980s, it protects steep karst cliffs, sea caves, and shallow coral gardens. Local fishing communities and Samui’s tourism industry have shaped access—boat operators now provide set-day routes to Talay Nai (the Blue Lagoon), Wua Ta Lap’s viewpoint, and Bua Boke cave.
Expect a day built around three activities: guided snorkeling over patch reefs, relaxed sea-kayaking between small islands, and a short but steep viewpoint climb (roughly 500 m with stairs). Beaches are soft white sand; underwater visibility varies with season and wind. Guides typically include basic safety briefings, life jackets, and dry bags; lunch is served onboard.
Practical edge: pick a calm-weather day, use reef-safe sunscreen, and pack a light change of clothes and water shoes. If you’re prone to seasickness, take prophylactics and sit mid-boat during crossings. The trip is accessible for most fit travelers but involves stairs, short hikes, and paddling bursts; plan for sun, salt, and showering facilities back on Samui after return.
Yes — basic masks, snorkels and life jackets are normally supplied, though bringing a personal mask improves fit and comfort.
Kayaking segments are generally short — multiple 30–60 minute paddles around islands, with transfers by longtail for some stretches.
Non‑swimmers can join; life jackets are required and activities can be adapted, but basic water confidence is recommended.
Policies vary; check the operator’s current guidance and disclose any medical conditions when booking—pregnant travelers and those with heart/back issues are typically advised not to join.
Oh-Hoo operates guided outdoor trips and adventures with an emphasis on safety, stewardship, and memorable experiences.
