More ways to explore the area's outdoor wonders
You step onto the early-morning pier as the sea breathes salt and light; the speedboat slices past sleepy mangroves toward the bright, sculpted silhouettes of the Similan Islands. The water here takes on a startling clarity that seems to push the reef into focus—coral ridges rise like folded rock gardens and currents thread the channels, nudging you toward walls and bommies where fish gather.

History
The Similan archipelago has long been a seasonal fishing area and was designated a national park in 1982 to protect its unique marine habitats.
Conservation
Strict park rules limit visitor numbers and activities during the season; use reef-safe sunscreen, don’t touch coral, and follow guides’ briefings to minimize impact.

Bring proof of certification
Carry your dive certification card and logbook showing recent dives—guides require minimum experience and recent activity.
Use a dive computer and SMB
Currents can be variable; a dive computer and surface marker buoy improve safety during drift or ascent.
Hydrate and pace breakfast
Long boat rides and diving cause dehydration—drink water before departure and avoid heavy meals that can cause discomfort.
Pack reef-safe sunscreen and seasickness remedies
Sun on the deck is intense and boat motion can unsettle some; reef-safe sunscreen protects corals and antiemetics ease nausea.

Required proof of certification and recent dive experience—operators will verify before boarding.
Personal dive computer
Tracks no-decompression limits and ascent information across two-tank profiles.
3mm wetsuit or shorty
