Kep is a scatter of places along a few kilometres of coast road rather than a town, so where you sleep decides how far you are from crab and whether you need a moto.
The crab market end
The cluster around Psar Kdam at the eastern end of the bay, within walking distance of every crab shack and the fish stalls. Noisy in the morning when the boats come in, and the only part of Kep where dinner does not require transport.
The hillside above the beach
The lanes climbing towards the national park, where guesthouses and small resorts sit among the ruined villas with sea views and a breeze. Ten minutes downhill to the beach and a long walk back up, so most people rent a moto.
Koh Tonsay — Rabbit Island
Basic huts on the sand, about twenty minutes by boat from Kep pier, with electricity for part of the evening and no shop, ATM or road. One night is right; two is a great deal of doing nothing.
Or base yourself in Kampot
Kep effectively closes after dinner — no night market, no strip, few bars. Kampot is 25km west and has everything Kep does not, and day-tripping over for lunch is what most people end up doing anyway.
