About this tour
When Alex from our BugBitten team ran this Ang Thong Marine Park tour, we set out from Koh Samui for a full day across a 42-island archipelago in the Gulf of Siam. The limestone islands rise sharply from shallow coral-studded waters, ringed by quiet beaches and dense forest. It's a proper mix of boat time, paddling, snorkelling, and either hiking or lazing depending on your mood — the kind of day that feels both active and spacious. The group was a standard tourist mix, nothing rowdy, and the pace let you breathe between stops.
Highlights
- Kayaking through calm, shallow straits between limestone cliffs
- Emerald lagoon framed by near-vertical rock walls — genuinely striking
- Snorkelling gear included; reefs were busy with life
- Thai lunch buffet on the boat — solid and hot when needed
- Optional hike rewards you with high-island views across the park
- Smaller group feel meant guides knew names and pacing wasn't rushed
- Plenty of float-and-swim time for those skipping the hike
What to expect
You'll start with a hotel pickup and a short drive to the pier, then board a decent-sized boat packed with maybe 30–40 people — enough company without feeling industrial. The boat heads out to the first island where kayaking kicks off; the water is glassy and clear, and paddling between those soaring limestone walls is genuinely peaceful. You'll hit a snorkelling spot next — the coral beds aren't pristine, but there's colour and fish if you're patient.
Around midday, lunch appears on deck: a Thai buffet with rice, curries, veg, and fresh-cut pineapple. The emerald lake stop is a highlight — you'll either swim in it or walk the short trail to a clifftop viewpoint. If you're up for it, a proper hike climbs higher for proper vistas; if not, swimming and sunbathing happen without judgment. The boat returns to Samui mid-afternoon. It's not rushed, but it's not languid either — a solid, middle-ground day.

Good to know
This tour covers the actual experience well — kayaking, snorkelling, a decent meal, and choices about how hard you want to work. The included kit (kayak, snorkel gear, lifejacket) means you're not hiring piecemeal. Guides are attentive and the group size stays manageable. It suits mixed-fitness groups because hiking and swimming are both options, not demands.
You'll be on a boat for hours with 30+ other people, so it's not intimate. The park entrance fee (300 baht per person) isn't included in the tour price — that's an extra cost to budget. Snorkelling reefs aren't pristine compared to deeper sites. The hike is steep and humid if you're not accustomed. Sun exposure is constant; bring sunscreen. Not suitable if you're pregnant or very unfit. Peak season (Nov–Feb) fills boats quickly. Dietary needs are accommodated but you must flag them at booking.
