Koh Muk lies forty-five minutes by longtail boat from Trang's Kuantungku Pier on the Andaman coast. It is known for Tham Morakot, a tidal sea cave that opens into a hidden sinkhole beach, and for an active Muslim fishing community along its eastern shore. Koh Muk is worth visiting if you want to swim through sea caves at dawn and eat freshly caught blue crab at plastic tables. Look elsewhere if you expect paved resort promenades, air-conditioned taxis, or all-night beach clubs.

Life on Koh Muk moves to the tide schedule. The eastern shore centres on the working pier and Muslim stilt village, while the western side curls around Had Farang and towering karst cliffs. You spend mornings timing boat trips into sea caves, afternoons dodging heat under casuarina trees, and evenings sharing spicy yellow curry with neighbours. It suits independent travellers who prefer quiet dirt paths over full-scale resort infrastructure.
Swim into Tham Morakot by 08:30 before tour boats arrive from the mainland. Walk across to the eastern village for fresh crab fried rice at a family-run stall. Spend late afternoon on the sands of Sivalai Beach, then catch a sidecar taxi to Had Farang for sunset and grilled sea bass. Select 1 Day above to see it.
Day two adds the interior jungle track. Hike up to the island viewpoint before midday heat, looking out over limestone ridges. In the afternoon, hire a kayak around the southwest bluffs, then sit down in the village for southern gaeng som curry and freshly made sweet roti. Choose 2 Days to expand the plan.
A third day allows a longtail boat charter out to Koh Kradan for shallow reef snorkelling and empty white sands. Return to Koh Muk to wander the eastern mangroves at low tide, watching mudskippers and shorebirds while the local fishing fleet heads out for night squid.
Plump blue swimming crab steamed with lime and garlic, wok-fried squid in sweet black ink, and whole grilled snapper pulled from the morning catch.
