More ways to explore the area's outdoor wonders
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.

Bring reef‑safe sunscreen
Choose mineral-based sunscreen to protect coral and reapply after swimming or paddling; bring a small zip bag to store it.
Protect your feet
Wear water shoes for rocky landings, cave approaches, and the viewpoint steps — sand can hide sharp coral.
Watch weather and wind
Sea conditions change quickly; check forecasts and heed guides—rough seas reduce snorkeling and kayaking time.
Prevent seasickness
If you are susceptible, take antiemetic medication before boarding and sit mid-ship during crossings.
Reef‑safe sunscreen (SPF 30+)
Protects skin and reef ecosystems during prolonged sun exposure on deck and in water.
Lightweight water shoes
Grip on wet rock, protection on coral beaches, and comfortable for short hikes to viewpoints.
Dry bag (5–10L)
Keeps phone, passport, and extra clothes dry during kayaking and boat transfers.
Personal snorkel mask
Familiar fit improves comfort and clarity compared with shared rental masks.
