Full description

South of Koh Lanta, the Trang islands are quieter than Phi Phi and every bit as beautiful. A wooden longtail boat takes you across to Koh Mook, where you swim through a pitch-dark tunnel in the cliff to emerge in the Emerald Cave’s hidden lagoon and beach.

The day continues with snorkelling over coral near Koh Chueak and Koh Ma, a lunch stop, and time on Koh Kradan’s long beach, one of the prettiest in Thailand. The exact islands visited depend on the tide and the sea.
