From Phnom Penh’s Streets to Koh Rong’s Beaches

Figuring out how to get from Phnom Penh to Koh Rong is easier than many first-time visitors expect. The journey isn’t defined by the kilometers you travel, but by how quickly Cambodia’s lively capital gives way to quiet beaches and island life. Phnom Penh’s café-lined streets, bustling markets, and riverside promenades gradually give way to Cambodia’s southern coastline before a speed ferry carries you across the Gulf of Thailand to one of the country’s best-loved islands.

Traveling between the two is refreshingly straightforward. Buses and shared vans connect Phnom Penh with Sihanoukville throughout the day, while frequent ferry departures make it easy to continue to Koh Rong, whether you’re heading for the lively atmosphere around Koh Toch or the slower rhythm of Long Set Beach.

This guide breaks down every stage of the journey, from choosing the right transport and understanding realistic travel costs to booking the correct ferry pier and making the most of your first day on Koh Rong.

Staying Near BKK1 Makes for an Easier Departure

If you’re catching an early bus to Sihanoukville, staying around BKK1 makes the day of departure much simpler. Mad Monkey Phnom Penh on Street 242 provides easy access to common pickup points while placing you close to Street 240, Rajana Crafts, The Gallerist, and Sisowath Quay.

Local Tip: Arrive at your pickup point at least 30 minutes before departure.

The Bus and Ferry Combination Is the Best Way to Reach Koh Rong

Reaching Koh Rong from Phnom Penh involves two connected journeys: an overland transfer to Sihanoukville, followed by a speed ferry to the island. While you can book each leg separately, many travelers choose a combined ticket that covers both the bus or van and the ferry, making transfers simpler and reducing the chance of missing a connection.

Whether you’re traveling independently or with friends, allowing a little extra time between arrivals and departures can make the day far more relaxed, particularly during weekends, public holidays, and the busy dry season.

Total Journey4.5 to 6 hours113,000 to 201,000 KHR ($28 to $50 USD)

Start with the Overland Journey to Sihanoukville

The first leg follows National Road 4, connecting Cambodia’s capital with its main coastal gateway. Buses and shared vans depart throughout the day, with journey times typically ranging from 4 to 5 hours depending on traffic and scheduled stops.

Established operators such as Giant Ibis, Virak Buntham, and Sorya run daily services alongside several smaller van companies. If you’re traveling during Cambodia’s peak travel periods, reserving your seat in advance is recommended.

Take the Ferry to Koh Rong

Once you arrive in Sihanoukville, continue to Ochheuteal (Serendipity) Pier, where speed ferries depart throughout the day for Koh Rong. Direct crossings usually take 30 to 45 minutes.

Traveler Tip: Morning departures usually offer the smoothest connections and are less likely to be affected by changing sea conditions.

Your First Day on Koh Rong Starts Here

Stepping off the ferry, you’ll quickly notice that Koh Rong moves at a different pace. Whether you arrive at Long Set Pier or Koh Toch Pier, you’re only moments away from powdery white sand, turquoise water, and beachfront cafés. Here’s how to make the most of your first few hours on the island.

Check In and Settle Into Island Life

If you’re staying on Long Set Beach, Mad Monkey Koh Rong is just a short walk from Long Set Pier, making it easy to drop your bags and settle in before heading out to explore. Take a few minutes to freshen up, grab a map if you need one, and check the day’s activities before starting your island adventure.

Unwind on 4K Beach

Also known as Long Set Beach, 4K Beach is one of Koh Rong’s longest and most scenic stretches of sand. Calm, clear water makes it an ideal place for a swim, while the wide shoreline offers plenty of space to relax under the palms or simply soak up your first views of the island.

Grab Lunch by the Beach

After your journey, enjoy a leisurely lunch at Long Set Restaurant, where you’ll find Cambodian classics alongside familiar Western favorites. It’s the perfect place to recharge before spending the rest of the afternoon exploring the island.

Explore Koh Toch

If you still have plenty of daylight, take a walk towards Koh Toch, the island’s livelier hub. Along the way, you’ll find beach bars, dive shops, convenience stores, and boat tour operators where you can arrange snorkeling trips, island-hopping excursions, or other adventures for the following day.

Join a Koh Rong Boat Party

If you’re looking to swap the beach for the open water, Mad Monkey Koh Rong Boat Party is a fun way to spend the day. Expect snorkeling stops, crystal-clear water, music, beach games, and plenty of opportunities to meet fellow travelers while discovering some of the island’s most beautiful coastal spots.

Stay for Sunset

As the afternoon fades into evening, head back to the beach and settle in for sunset. Watching the sky change color over the Gulf of Thailand is one of the simplest yet most memorable ways to begin your time on Koh Rong, whether you’re sharing a drink with new friends or enjoying a quiet moment by the water.

Local Tip: Arriving before mid-afternoon gives you enough time to check in, explore, and enjoy sunset.

If you’re planning to stay a little longer, there’s plenty more to discover beyond your first afternoon. From hidden beaches and snorkeling trips to nightlife, local food, and island adventures, Koh Rong has more to offer than meets the eye.

Frequently Asked Questions About Traveling from Phnom Penh to Koh Rong

How long does it take to get from Phnom Penh to Koh Rong?


Most journeys take 4.5 to 6 hours, including the overland transfer from Phnom Penh to Sihanoukville, the ferry crossing, and the time needed to transfer between the bus station and the pier. Travel times may be slightly longer during weekends, public holidays, or the rainy season when traffic and sea conditions can affect schedules.

How much does it cost to travel from Phnom Penh to Koh Rong?


Expect to spend approximately 113,000 to 201,000 KHR ($28 to $50 USD) per person. Your total cost depends on whether you book a combined bus-and-ferry ticket or purchase each leg separately, as well as the operator and travel season. Booking in advance during peak periods often gives you more departure choices.

Can you travel from Phnom Penh to Koh Rong in one day?


Yes. Daily buses, vans, and speed ferries make it possible to travel from Phnom Penh to Koh Rong in a single day. Choosing an early morning departure gives you the best chance of arriving with enough time to check in, enjoy the beach, and catch the sunset on your first day.

Should I book a combined ticket or separate tickets?


For most travelers, a combined bus-and-ferry ticket is the easiest option. It simplifies transfers, reduces the stress of coordinating different operators, and is often similarly priced to booking each leg individually. If you’re planning to spend time exploring Sihanoukville before continuing to the island, separate tickets may offer more flexibility.

Which ferry pier should I choose?


That depends on where you’re staying. If your accommodation is on Long Set Beach, choose a ferry that stops at Long Set Pier for the shortest walk after arrival. If you’re staying near the restaurants, bars, and dive shops around Koh Toch, book a ferry that arrives at Koh Toch Pier.

Is Koh Rong worth visiting?


If you’re looking for white-sand beaches, clear water, island nightlife, and a slower pace than Phnom Penh, Koh Rong is one of Cambodia’s standout island destinations. Stay for two or three nights to experience the island properly. You’ll have time to relax on the beach, join a snorkeling or boat tour, explore different corners of the island, and enjoy both its lively and laid-back sides.

What should I do after arriving in Koh Rong?


Start by checking into your accommodation and taking a little time to settle in. If you’re staying near Long Set Beach, spend the afternoon swimming or unwinding on 4K Beach. Grab a leisurely meal at a beachfront restaurant, then head to Koh Toch if you want to explore more of the island. End your first day with a sunset before planning snorkeling, island hopping, or diving for the days ahead.
