Hotels Near Mu Ko Similan National Park — Where to Stay for Thailand's Best Diving

The Similan Islands are consistently ranked among the top ten dive sites in the world. Nine islands of undisturbed national park — granite boulders, white sand beaches, and gin-clear visibility over coral gardens with manta rays, whale sharks (seasonal), leopard sharks, and extraordinary reef fish. There are no hotels on the Similan Islands themselves — everyone stays on the mainland and day trips out.

That mainland is Khao Lak — a beach town 80km north of Phuket serving as the primary base for Similan dive trips, with accommodation significantly cheaper than Phuket for equivalent quality.

Understanding the Logistics

The Similan Islands are only accessible November through May. The national park closes entirely during monsoon season (approximately June to October) to allow reef recovery. No exceptions. Day trips depart from Tab Lamu Pier at around 7am and return by 5-6pm. Live-aboards spend 2-5 nights anchored at the islands for dramatically more dive time.

Surin Islands to the north have the Moken sea nomad village — one of the most extraordinary cultural experiences in southern Thailand.
