A few companies (and guesthouses such as Blue Moon) offer excursions to waterfalls upstream or the beaches on nearby Koh Kong island. The boat ride there takes about an hour (although the choppy seas shouldn’t be crossed between June and October). Guided treks into the hinterland are also easily arranged.
