About this tour
Join TourInKohSamui.com for a relaxed full‑day cruise to Mu Ko Angthong Marine Park, a protected archipelago of 42 limestone islands west of Koh Samui. Travel on a spacious big boat with plenty of shade, visit the Emerald Lagoon on Koh Mae Koh, hike to a panoramic viewpoint on Koh Wua Talap and enjoy snorkeling and optional kayaking in turquoise water. This is the most budget‑friendly way to see Angthong while still packing in the key highlights. Want more reef time closer to shore? Pair it with a snorkeling day trip from Koh Samui to Pig Island (Koh Madsum) & Koh Tan. Prefer a full day at Koh Tao’s reefs instead? See our Koh Tao & Koh Nang Yuan day trip from Koh Samui.

About the kayak: sea kayaking on this big boat tour is the one optional extra and it is not part of the ticket price. Add a kayak when you book, from 380 THB per adult, and use it at the lagoon stop. Everything else is already in the price you see, including hotel pickup and the Angthong Marine Park entrance fee, so there is nothing to pay at the park.

What to Expect on the Angthong Day Trip
A full day (around 8–9 hours) on and around the water, with a mix of cruising, light hiking, swimming and relaxing. Group size is typical of a big boat economy tour: more social, with other travelers on board, but with plenty of shaded deck space. Around 1.5 hours cruising each way between Koh Samui and the marine park, with island scenery all around you. A moderate climb to the main viewpoint at Koh Wua Talap; steep sections and steps mean it is better for guests with reasonable fitness and good footwear. Opportunities to swim and snorkel in designated areas; visibility and marine life can vary with season and tides.

The big boat is larger, slower, and more affordable. It carries more passengers and offers a social atmosphere with generous deck space. The speedboat is faster and keeps group sizes smaller, but costs more. Both visit the same park highlights.

When is Angthong Marine Park open?
The park is open roughly from late December through October. It typically closes from 1 November to 23 December due to monsoon season in the Gulf of Thailand.
Do I need snorkeling experience?
No. The snorkeling areas inside the park are calm and shallow. Equipment is available on board.
Where does this tour depart from?
Hotel pickup is included from all major areas on Koh Samui. The exact departure pier is shared on your voucher after booking.
Which islands do you visit on this island hopping tour from Koh Samui?
This island hopping day trip from Koh Samui cruises through the Ang Thong (Angthong) Marine Park archipelago, a protected group of 42 islands about 90 minutes northwest of Samui. The big boat stops at Koh Mae Koh for the Emerald Lagoon (Talay Nai), at Koh Wua Talap for the panoramic viewpoint hike and the national park headquarters beach, and at a sheltered bay for snorkeling and kayaking.

Not sure which boat suits your day? Compare all four Ang Thong Marine Park tours from Koh Samui in one place — this big boat day cruise, the VIP speedboat, the traditional sailing cruise and the private speedboat charter — with the current "From" price shown on every card.
Free in the evening after the boat gets back? The tour returns to your hotel 17:00–18:00, which leaves time for Muay Thai fight night tickets at Samui International Stadium in Chaweng — fight nights on Tuesday, Friday and Sunday, doors from 20:00 and the first bout at 21:00, a full card of 6+ fights building to the main event, and a choice of Stadium, Ringside or VIP seating delivered as an e-ticket (hotel transfers available as an optional add-on).
Planning a land day around the boat day? Book the half-day ethical elephant sanctuary tour in Koh Samui — about 3 hours on site on forested land in the north of the island, with morning and afternoon sessions daily: help prepare a healthy snack and feed the rescued elephants, walk the grounds while they roam, watch pool and mud bath time, and finish with a vegetarian meal overlooking the paddocks. Hotel pickup and drop-off by air-conditioned vehicle is included, and there is no riding and no shows. Handy for the weeks when Angthong Marine Park is closed for the monsoon (1 November to 23 December).
Free hotel pickup is included from most areas. If your hotel is in Bang Po, Nathon, Lipa Noi, Lipa Yai, Butterfly Garden, Taling Ngam or Phang Ka, an extra transfer of ฿300 per person applies.
