Verified experiences and guided adventures in the surrounding area.

Boarding a longtail as dawn light slants across Koh Samui, you push off into a scatter of islands that rise like ancient towers from the Gulf. Paddle strokes slice glassy water, and limestone cliffs close in around emerald coves; at times the sea seems to be testing you, the current nudging the bow while wind teases spray into your face.

History

The park was declared a national marine park to protect its coral reefs and unique karst islands; local fishing communities historically used these waters for subsistence.

Conservation

Visitors are encouraged to use reef‑safe sunscreen, avoid touching coral and pack out all rubbish—marine parks enforce rules to limit anchoring and reef damage.

Adventure tips

Start EarlyMorning crossings are calmer and cooler—aim to board at first light to avoid midday winds and heat.

Protect Your CameraUse the provided waterproof dry bags and bring a small strap to secure cameras to your PFD or kayak.

Shoes for Both Sea and LandWear reef shoes or old trail runners for paddling and for the short, sometimes slippery walks to viewpoints.

Pace Your HydrationBring extra water and sip regularly; salty spray and sun combine to dehydrate even on overcast days.

Recommended gear

Reef/water shoes: Protect feet on rocky landings and provide grip in wet kayak cockpits.
Light dry bag (small): Keep phone, documents and snacks dry during transfers and paddling.
Reef‑safe sunscreen and hat: Protects skin from prolonged tropical sun without harming marine life.
Light quick‑dry layers: Provides sun protection and warmth for early departures and breezy crossings.
