Sparkling like a starry sky all around you, Koh Rong’s bioluminescent plankton are a wonderful sight to behold at night times. (Learn why they glow on Wikipedia)
Although this phenomenon is abundant on the islands, the glowing plankton can only be seen in places with very little light pollution. As such, if you’re staying on Koh Touch (the main tourist area on Koh Rong Island) or on Saracen Bay (the main tourist area on Koh Rong Samloem), the easiest way for you to see the plankton is by booking a boat tour (you can also walk to Police Beach on non-party nights (15 minutes left from the main pier) and Tree House Bungalows (15 minutes right from the main pier) on Koh Touch, or make your way to Long Set Beach around the corner from Koh Touch).
Booking a tour is very straight forward – You’ll see them advertised all around the beach. A trip to see the plankton will cost about $5 (leaving at 7pm). You can also see the plankton during boat trips that will include snorkeling, fishing, BBQs, and sunsets. These tend to cost around $10 and are from 1pm – 7pm. You can book some of these activities online now and save up to 15%:
A couple of resorts are also well situated so as to see the plankton glow at night times. Of these, we would recommend the fantastic Longset Resort, located on the beautiful Long Set Beach. Providing a little bit of luxury during your stay, here you can see the glowing plankton when the sun goes down.

Q: How do I get to Koh Rong?
A: There are now 5 modern ferry services from Sihanoukville to Koh Rong Island – Speed Ferry Cambodia, Island Speed Boat Cambodia, Buva Sea, Angkor Speed Ferry, and GTVC. (There are also a couple of $5-$10 ‘Slow Boat’ services that take 1.5 – 2.5 hours – These services are not professionally run and are not recommended).
It will take about 40 minutes to get to your destination if it’s the first stop. If the boat first stops elsewhere, it may take 1 hour or so.
All 5 services will charge roughly $25 return, though prices can vary depending on time of year, special offers, etc. All services leave from the Ochheuteal (AKA ‘Serendipity’) pier in Sihanoukville and go to the main tourist beaches on the islands. If your hotel is not on the main beaches (Koh Touch / Saracen Bay), please read Sihanoukville to Koh Rong.
The 5 services offer modern speed boats with comfortable chairs, life jackets, and the option to buy food and drink on board. Not all of the ferries have air-conditioning, but once the boats set off there is a strong cool breeze throughout the sitting areas which more than makes up for it.
All ferry services tend to be very busy – we strongly recommend you buy your tickets in advance. You can buy your tickets online now here: Book Ferry Tickets Online Now
Q: Is Koh Rong a party place?
A: Please ignore what you might read elsewhere – Koh Rong is NOT just a party place! Yes, the main tourist area, Koh Touch, has a reputation for being quite lively, but there are MANY other areas that are peaceful, relaxing, and truly mesmerising. Even on Koh Touch itself there are beautiful, quiet areas a little further down the beach. Please read our Hotel Guide and Beach Guide for more information.
Q: Where are the best beaches?
A: There are many wonderful beaches on Koh Rong. To give you an idea, here are three beaches that we like (please read our Beach Guide to learn more):
1) Lonely Beach – Possibly the best beach on the islands (even bettering Lazy Beach on Koh Rong Samloem), is Lonely Beach to the northern side of Koh Rong Island. Although it is not in the most convenient location, it really is absolutely stunning. The small alcove feels like a real island-paradise, with crystal clear ocean waters, soft white sandy beaches, and tall palm trees all around. The atmosphere is quite serene – so peaceful and quiet with just a few crickets chirping in the background. There are very few people around, so you feel quite isolated and secluded out in a truly beautiful setting.
2) 4K Beach (Long Set Beach) – We would say that 4K beach is number two on the list, though there are now several resorts built along this wonderful stretch of white sand, sparkling turquoise ocean, and tropical jungle wilderness. What’s great about this beach, apart from the stunning scenery and inviting pristine waters, is that it’s a short walk away from the main tourist area on Koh Rong Island (Koh Touch).
3) White Beach – At number 3 we are going to put White Beach – A 10 minute walk from the main pier on Koh Touch. Admittedly, there are probably better beaches, but the convenience of White Beach and the quality of the resorts around this area push it up a place or two. Despite what you might read elsewhere, this far side of Koh Touch is not a party location and does not suffer from the same setbacks that other more popular areas experience. The beach on this part of the touristy stretch is clean and well-kept, with soft white sands and beautiful clear ocean waters.
Q: What should I bring with me?
A: We recommend that you bring plenty of cash, mosquito spray, sun tan lotion, and any other necessities. Both islands have small shops where you can buy most of what you might need, but prices can be inflated so it’s a good idea to stock up on the essentials before you go.
Q: Is it easy to get a Cambodian Visa?
A: Yes – it is generally very easy to get a Cambodian Visa. Although there are tighter restrictions for Business Visas (which now require a Cambodian work permit), the Tourist Visa (1 month stay) is very straight forward and can be obtained at the airport / border crossing as you arrive. If you’d like to skip the ques, you can buy your visa online now here: Buy a Visa Online Now.
Q: Is there an ATM on the islands?
A: Although there is no ATM as such, you can still get cash out at any of the three Eftpos terminals on Koh Touch (the main tourist area on Koh Rong Island). There is an Eftpos terminal at Green Ocean Guesthouse, White Rose Guesthouse, and Koh Lanta.
Q: Is there a medical facility on Koh Rong?
A: There is a medical facility on Koh Touch (the main tourist area on Koh Rong Island). Please ask someone when you are there for directions.
Q: Is it a family-friendly place?
Q: When is the rainy season?
A: The rainy season on Koh Rong Island is from the middle of May to early November. During these months there will be short bursts of heavy rain during the day. One thing to note is that, although it is wonderfully hot throughout the peak season, there are several advantages of visiting the islands during the rainy season.
For example, those that visit during the rainy season get to enjoy half-priced accommodation and beautiful rainy scenes, and because it never gets too cold in Cambodia, swimming in the ocean is still a very pleasurable experience (the water rarely drops beneath 25°C).

Q: Where was Survivor Kaoh Rong filmed?
A: Koh Rong Cambodia has hosted the popular reality programme ‘Survivor’ several times.
In 2012, a special edition of the French Survivor (‘Koh Lanta’) was filmed near Sok San Village with an All-Star cast. The production team returned in 2013 and again in 2016 to film the regular editions.
In 2015, the American version of Survivor produced Season 31 (Survivor: Cambodia – Second Chance) and season 32 (Survivor: Kaoh Rong – Brains vs Brawn vs Beauty) on Koh Rong Island.
The 16th edition of Expedition Robinson (Sweden’s Survivor) was also filmed on the island.
