Regular crossings from Sihanoukville (the port area that serves travelers heading to both islands) are operated by speedboat or “speed ferry”. Daily, several trips connect Koh Rong and Koh Rong Sanloem; the most popular route is often to Koh Rong Sanloem (many departures in the morning until the afternoon during high season, depending on the company and schedule). In practice, expect thirty minutes to about an hour depending on whether you are heading to the main village of Koh Rong, Saracen Bay on Sanloem, or another cove.
The well-established companies include GTVC (GTVC Cambodia), Speed Ferry Cambodia, and Island Speed Ferry. They may have different schedules, prices, and sometimes different docks — avoid being at the wrong pier: the journey to the islands is short; the stress comes more from the wrong meeting point than from the crossing itself.
Key information before paying
Where does the boat dock?
On Koh Rong, the most common arrivals are near Koh Touch (a lively village with guesthouses and bars). Other services serve Long Set Beach (often referred to as Long Beach in traveler vocabulary) or Coconut Beach depending on the line and season — specify at the time of purchase which access block you will use from the pier.
On Koh Rong Sanloem, the usual drop-off points are Saracen Bay — a protected bay, ideal as a hub — and at certain times M'pai Bay. Other services mention a point like Eco Sea Dive (associated center or mooring area): the exact name must always appear on your reservation; avoid arriving at Saracen if your bungalow is on the M'pai side, unless arranged on the island with a transfer.
Booking and payment
Booking only on the same day, during high season, is not always sufficient: boats can be full during peak times (long weekends, holidays, local vacations). Booking online or purchasing a ticket at least the day before significantly reduces the risk of being left without a seat.
On-site, a tuk-tuk from the center to the port area usually takes little time if you show them the address or the screenshot sent by the operator; avoid the implicit assumption “everyone always departs from the same dock,” as access points can change depending on the season and construction.

Prices and schedules can change quickly — they serve to validate the market state, not to guarantee line by line your physical ticket.
Questions fréquentes
These are two neighboring islands from the same port. Sanloem is often perceived as quieter (bays like Saracen Bay); Koh Rong is larger, with Koh Touch for nightlife and Long Set (Long Beach) for long stretches of sand. Travel time and the dock may differ — check your ticket.
In high season (December–February, major holidays or busy weekends), yes — at least the day before or online to secure your slot. In low season, you can sometimes buy at the ticket counter on the same day, but leave some buffer time before a flight or long-distance bus.
Very few ATMs, often none depending on the beaches; cards are not accepted everywhere or incur fees. Bring enough cash in USD from Sihanoukville (and small denominations).
Seasonal offers or direct shuttles may be available depending on the year and operators; they change quickly. A reliable option: the Kampot/Kep road then bus or taxi to Sihanoukville, followed by speedboat. Also, check with your guesthouse for the latest direct trips announced.
