How to Get to Koh Sdach From Phnom Penh, Sihanoukville, or Koh Rong
You can reach Koh Sdach by combining an overland leg with a boat transfer, or by boat directly from a nearby island. Most travelers head to Phnom Penh or Sihanoukville first, then board a boat operated by Buva Sea Cambodia; visitors coming from Koh Rong can make the crossing in around 45 minutes.
No flights or large ferry terminals are serving Koh Sdach, which is one of the reasons the archipelago has remained quieter than Cambodia’s more developed islands.
If you’re travelling from Phnom Penh, Siem Reap, or Sihanoukville, operators such as VET Air Bus Express connect major cities to the coastal departure points near Kiri Sakor District. From there, Buva Sea Cambodia operates scheduled boat transfers to Koh Sdach, with journeys taking approximately 1 hour 30 minutes from Sihanoukville and 45 minutes from Koh Rong.
Another option is to travel overland to Koh Kong Town, where local boats make the short crossing to Koh Sdach in around 10 to 15 minutes, depending on tides and weather conditions.
Cash tip: There are no ATMs or banks on Koh Sdach or its surrounding islands. Bring enough Cambodian riel or US dollars to cover accommodation, meals, and boat hire before leaving Phnom Penh, Sihanoukville, or Koh Kong.
Where to Stay for Island Hopping Around Koh Sdach
Koh Sdach isn’t an island of large resorts or beachfront strips lined with hotels. Accommodation is scattered between the fishing village and quieter stretches of coastline, keeping everything within easy reach of the boats that connect the archipelago.
Staying on the island means the day starts where local life does. Longtail boats leave from the village each morning, restaurants and small shops sit along the waterfront, and it’s easy to head out early before returning in time for sunset.
Mad Monkey Koh Sdach sits on a private beach a short walk from the village, making it one option for travelers who want quick access to island-hopping departures while staying close to the rhythm of the island.

What to Expect on an Island-Hopping Trip
Island hopping here runs on flexibility rather than a fixed schedule. You’ll work with a local boat captain to shape a route around the weather, sea conditions, and whatever you’re in the mood for.
Most trips begin from Koh Sdach’s fishing village, where longtail boats head out across the archipelago to quiet beaches, snorkeling spots, and uninhabited islands. Depending on your itinerary, you can spend a few hours exploring nearby islands or dedicate a full day to discovering some of the archipelago’s more remote corners.
Each stop feels different. One island invites you into calm, shallow water for snorkeling, another offers a beach with barely another footprint in sight, while the next is little more than sand, sea, and a boat waiting offshore until you’re ready to leave.
Because facilities on the outer islands are limited, it’s a good idea to bring drinking water, snacks, sunscreen, and anything else you’ll need for the day. Once you leave the main island, you’re unlikely to find shops, restaurants, or mobile reception until you return.
Route tip: Ask your boat captain which islands have the calmest water that day. Conditions shift with the tide, and locals will know which beaches and snorkeling spots are worth it that particular morning.
Best Islands to Visit Around Koh Sdach
The Koh Sdach Archipelago is made up of 12 islands, most of them uninhabited and accessible only by longtail boat. Some are known for snorkeling, others for long stretches of empty beach, while a few are best explored as part of a full-day journey across the Gulf of Thailand. If you’re only visiting for a day, choosing the right combination of islands will make a bigger difference than trying to see them all.
| Island | Best For | Highlight |
|---|---|---|
| Koh Totang | Snorkeling | Coral reef, clear water, and quiet beach |
| Koh Ach Seh | Swimming | Calm, shallow water close to Koh Sdach |
| Koh Bong | Relaxing | Long sandy beach, picnic spot |
| Koh Chhlam | Longer boat trips | Remote coastline, often paired with fishing |
| Koh Ampil | Full-day itineraries | Peaceful stop on longer island-hopping routes |
Koh Totang
For many visitors, Koh Totang is the highlight of the archipelago. Coral reefs sit just offshore, making it one of the best places to snorkel around Koh Sdach, while the beach itself remains largely untouched. Bring your own snorkeling gear if you have it, along with drinking water and sunscreen, as there are no facilities once you arrive.
Koh Ach Seh
Only a short ride from Koh Sdach, Koh Ach Seh is known for its calm, shallow water and easy access. It pairs naturally with Koh Totang on a half-day trip, giving you time to swim, snorkel, and enjoy the quieter side of the archipelago without venturing too far from the main island.
Koh Bong
Koh Bong is where the pace slows even further. Long stretches of sand, gentle waves, and very little development make it an ideal stop for a picnic, a swim, or simply spending a few unhurried hours by the water.
Koh Chhlam
Located farther from the main island, Koh Chhlam rewards those with a little more time. Longer boat charters often include the island alongside a fishing stop, offering a chance to experience one of the quieter corners of the archipelago.
Koh Ampil
On the outer edge of the archipelago, Koh Ampil is often included on full-day routes. While many visitors stop only briefly, its peaceful setting makes it a worthwhile addition if you’re exploring beyond the islands closest to Koh Sdach.
Safety tip: Sea conditions can change throughout the day, especially during the rainy season. Confirm your route and return time before leaving, and always wear the life jacket provided on the boat.
How to Book a Longtail Boat for Island Hopping
Boat trips are easy to arrange once you’re on Koh Sdach. Local operators offer private longtail boat charters, giving you the flexibility to choose the islands you’d like to visit, how long to spend at each stop, and whether you prefer a half-day or full-day trip.
If you’re staying at Mad Monkey Koh Sdach, the team can also help connect you with local boat operators.
Half-day charters suit two or three nearby stops, while a full-day booking gives you more room to reach the archipelago’s farther islands. If you’re traveling as a group, one boat for everyone is usually the simplest option.
Try to book the day before you plan to leave. It gives operators time to prepare and helps with availability during weekends, holidays, and Cambodia’s peak season.
Booking tip: Confirm which islands you’ll visit, how long you’ll stay at each, and the total price before the boat leaves. Mobile signal drops off quickly once you’re away from the main island, so settle the plan up front.
Before You Head Out for an Island-Hopping Trip
Once the boat leaves the village, the rest of the day belongs to the archipelago. Shops, restaurants, and mobile signal quickly disappear, so arriving prepared means you can enjoy the journey.
Before setting off, make sure you have:
- Drinking water to stay hydrated throughout the day.
- Sunscreen, a hat, and swimwear for long hours under the sun.
- A towel and a dry bag to keep your valuables protected. Snorkeling gear, if your boat operator doesn’t provide it.
- Enough cash for boat hire, meals, drinks, and any unexpected expenses, as there are no ATMs on Koh Sdach.
With everything packed, you’re ready to spend the day exploring some of Cambodia’s quietest islands without needing to head back to the village for forgotten essentials.
Things to Do in Koh Sdach Beyond Island Hopping
Island hopping may be the main reason to visit, but Koh Sdach reveals itself just as much between boat trips. Life here moves at the pace of a working fishing community, making it easy to slow down without feeling like you’re missing out.
Wander Through the Fishing Village
The village is compact enough to explore on foot. Fishing boats come and go throughout the day, neighbours gather along the waterfront, and a handful of family-run shops give a glimpse into everyday life on the island.
Slow Down by the Beach
Island hopping doesn’t have to fill the whole day. Back on Koh Sdach, it’s easy to spend a few hours swimming, reading in the shade, or simply watching fishing boats move across the Gulf of Thailand before heading out again tomorrow.
Stay for Sunset
Evenings on Koh Sdach arrive without much fanfare. As the day cools, the coastline becomes a peaceful place to sit by the water before darkness settles over the archipelago.
End the Day with Something Social
After a day on the water, some travelers head back to the beach, while others look for a more social way to spend the evening. Depending on the night, Mad Monkey Koh Sdach hosts activities such as beach volleyball, quiz nights, karaoke, live music, and other community events that are open to guests and visitors alike. It’s an easy way to meet fellow travelers before heading back out to explore the islands the next day.
