Apart from sticking your toes in the sand and sipping cocktails, tours to outlying islands are the main attraction in Sihanoukville. Contact the friendly folks at EcoAdventures (Samudera Market, Town Center, Sihanoukville; tel. 012/654-104; www.ecosea.com). They arrange great day tours with stops in remote coves where clients can snorkel or take a scuba course. The diving is mostly shallow, and the visibility varies, but EcoAdventures is a very professional outfit, and a day on their boat -- whether diving, snorkeling, or taking in the scenery over their tasty lunch buffet (or diving off the top deck) -- is alone worth the trip down to Snooky.
For tours to outlying hills or on to Bokor, contact the friendly folks at Eco Trek Tours Cambodia at Mick and Craig's Sanctuary (tel. 016/876-200; ecotrektourscambodia@yahoo.com). For car and taxi service on to any other parts of the area, contact any hotel front desk.
