Morning light cuts across the Andaman as the speedboat slips from Thap Lamu pier and the sea takes over — cool spray, a rising horizon and the island silhouettes sharpening into granite sails. By mid-morning you’re anchored in clear water, fins slicing through schools of angelfish while coral gardens fan out below like underwater ridgelines. The Similan Islands demand attention: white sand beaches, sculpted boulders, and a handful of named bays that photographers chase for the right curve of light.

History
The Similan Islands were designated a national park in 1982 to protect marine habitats; local coastal communities historically relied on small‑scale fishing.
Conservation
The park restricts visits seasonally to allow reef recovery; visitors should avoid stepping on coral, use reef‑safe products, and follow guide instructions to minimize impact.

Book in the open season

Bring reef‑safe sunscreen
Apply biodegradable sunscreen before entering the water to protect coral and avoid rubbing it on your snorkel gear.
Prepare for sea motion
If you’re prone to seasickness, take preventative medication and sit mid‑boat where motion is least felt.
Pack a quick dry change
Wet swimsuits and sun exposure can get uncomfortable on the return—bring a dry top and a light towel.
Reef‑safe sunscreen
Protects reefs and prevents sunburn during prolonged time on water and sand.
Lightweight water shoes
Protects feet on rocky shorelines and reef entries.
Snorkel mask (personal)
Personal masks fit better than rental gear and reduce fogging—operators usually supply basic equipment.
Dry bag (10–15L)
Keeps phone, documents and a dry change of clothes safe from spray and waves.
