The speedboat peels away from Bophut’s jetty and the Gulf opens wide: flat, green-blue water punctuated by limestone islands that rise like sudden walls. Wind pulls at your hat and the engines set a quick cadence as you cross to Ang Thong Marine National Park, where hidden coves and a salt-stiff smell of sea meet forested cliffs.

History
Ang Thong was established as a marine national park to protect its karst islands and marine habitats; the archipelago has long been part of local fishing routes off Koh Samui.
Conservation
Park regulations restrict anchoring and removing marine life; operators encourage reef‑safe practices and carry out beach cleanups to reduce plastic and anchor damage.

Book a morning departure
Seas are typically calmer first thing and visibility for snorkeling is better before afternoon winds pick up.
Use reef‑safe sunscreen
Protect coral by choosing mineral-based sunscreen and reapply sparingly before entering the water.
Bring a dry bag
Keep phones, spare clothes, and documents dry on an open boat; zippers and clips add security on choppy crossings.
Pack motion‑sickness remedies
Even short crossings can be bumpy; pills or acupressure bands help if you’re prone to seasickness.
Reef‑safe sunscreen
Protects both your skin and the park’s coral ecosystems during long sun exposure.
Waterproof dry bag
Keeps electronics, paperwork, and spare clothes dry on open boats and during wet landings.
Snorkel gear (mask & fins)
Personal gear fits better than rentals and improves comfort and visibility in the water.
Non‑slip deck shoes or aqua sandals
Provides grip on wet surfaces and comfortable traction for beach landings and short hikes.
