Ko Hin-Ngam — the "island of beautiful stones" — is a tiny outcrop a short longtail ride west of Ko Lipe, and most snorkel tours stop here for half an hour. The entire beach is composed of dark, sea-polished pebbles of every size, gleaming wet at the waterline and clattering musically when waves wash over them. There is no sand at all, and the effect is striking — particularly in late afternoon light.
A short trail leads to a rocky high point with a good view of the surrounding islands. Swimming around the pebble beach is rocky and best done with reef shoes; the snorkelling just offshore over the corals is excellent. Do not pocket any pebbles, even small ones — both the rangers and the curse take it seriously.
