About Koh Tonsay#
Koh Tonsay, which translates loosely as Rabbit Island, is a small sandy island off the south coast of Cambodia, the nearest mainland town being Kep. It is deservedly popular for its long, shallow slope off the beaches, which makes for better swimming than the mainland shores. The water tends to be surprisingly clear and calm, good for snorkelling, though there is little coral and not a huge variety of fish.
The whole island covers only about two square kilometres. A couple of guesthouses offer overnight stays; reservations are rarely needed, as touts for both places tend to greet arrivals on the Kep mainland and book them in before they have even boarded the ferry.
Wild horses roam the island’s interior and only a handful of families live here, giving Koh Tonsay a peaceful character suited to travellers after quiet and relaxation. It is not a party island, though holiday weekends can get considerably livelier as Cambodians and Phnom Penh residents take over the rooms.
How to Get to Koh Tonsay#
Ferries and longtail boats depart from Kep’s pier; the crossing takes about 10-20 minutes depending on boat type. Boats run more frequently in the morning and return trips are available throughout the day.
Tips for Visiting Koh Tonsay#
- Take the short boat ride from Kep's small pier early to avoid midday tourist peaks.
- Explore inland paths to find quieter beaches-most visitors linger near the main jetty and beach.
- Try the fresh seafood at the few shore restaurants on the island; they are basic but freshly caught.
