We planned two days at M’Pai Bay. We stayed ten. That’s not unusual — something about M’Pai Bay on Koh Rong Sanloem scrambles your timeline. You arrive thinking you’ll have a quick look and move on. A week later you’re regulars at a breakfast spot hidden down a side alley, you’ve done the hike to Clear Water Bay twice, and you’ve started recognising other people’s orders at dinner.

This is a guide to the best places to stay and eat in M’Pai Bay, based on what we actually tried over those ten days. It covers the two main hostels, four restaurants that are worth seeking out (some literally not on Google Maps), and a few things you need to know before you arrive.

M’Pai Bay vs Saracen Bay: which should you choose?

Koh Rong Sanloem has two main beaches that travellers base themselves on, and the right one depends what you’re after.

Saracen Bay is the island’s main beach — long, white, calm water, and lined with a mix of budget and mid-range accommodation. It’s more developed, has more food options, and is where the majority of tourists stay. If you want a beach holiday with reliable infrastructure, Saracen Bay is the choice.

M’Pai Bay is the backpacker village at the northern end of the island. It’s reached by a separate pier (some ferries stop here directly; others require a short water taxi from Saracen Bay). The beach is smaller, the vibe is more social, and almost everything is cheaper. M’Pai Bay also faces west, which means the sunsets are among the best anywhere on the island — and the bioluminescent plankton in the water at night is a genuine phenomenon, not just a travel cliché.

If you want to hike to Clear Water Bay — the most beautiful and most isolated beach on Koh Rong Sanloem — you need to be based at M’Pai Bay. The trail starts at the south end of the beach and takes about 1.5 hours through jungle and coastline.

For a full-day Koh Rong Sanloem beach tour from Sihanoukville that covers the ferry and key beaches with BBQ lunch, book through Viator rather than arranging the ferry independently.

Where to stay in M’Pai Bay

M’Pai Bay doesn’t have a huge range of accommodation — it’s a small backpacker village, not a resort beach. These are the two places we’d recommend, both of which we stayed at.

The Cliff Hostel

The Cliff Hostel is built into the cliff at the north end of M’Pai Bay — a ten-minute walk from the village, but completely worth it. The hostel has a large sundeck which is, without question, the best spot on the bay for watching the sunset. You sit up above the trees with an unobstructed view west over the water. On most evenings, half the beach walks up to watch it.

A long flight of wooden steps takes you from the hostel down to the sea, where you can snorkel directly off the rocks. The underwater visibility at this end of the bay is good, and the rocky shore attracts more marine life than the sandy beach. Accommodation is a mix of dormitories and private rooms — budget to mid-range, with prices from around $10–30 per night depending on season and room type.

Yellow Moon

If The Cliff is about sunsets and snorkelling, Yellow Moon is about the party. It sits right on the beach in the heart of the village, with direct beach access and a bar that keeps going late. The atmosphere is great — good music, good crowd, the kind of hostel where you end up talking to everyone. Don’t expect much sleep; that’s not what it’s optimised for. If you’re travelling solo and want to meet people quickly, this is the one.

Where to eat and drink in M’Pai Bay

The food scene in M’Pai Bay is small but genuinely good. Most of the best places are run by individuals or couples — some don’t have websites or Google Maps listings, which is part of their charm. Here’s what we’d recommend.

The best breakfast: The Sea Pony

The Sea Pony is hidden in a side alley off the main village road — you’ll walk past it if you’re not looking for it. This hostel and café offers an all-day breakfast menu with proper vegetarian, vegan, and gluten-free options, and they make their own bread. In a place where breakfast often means a sad plate of eggs and toast, The Sea Pony is a genuine find.

The portions are large enough to carry you through to dinner, the price is fair, and the coffee is good. This was the best breakfast we had in all of Cambodia. Go early — it fills up, and the alley seating is limited.

Best for dinner: Khuntea Khmer Kitchen

Khuntea Khmer Kitchen is a small restaurant run by Khuntea and her partner Hadrien — an open kitchen and plastic chairs in the sand, near a dirt road at the top of the village main street. The menu is short and changes based on what’s at the market. Everything is fresh. The fish in particular is exceptional — we ate their BBQ Barracuda and went back the next night to do it again.

On our second visit, Hadrien offered to let us pre-select the next day’s tuna so they could prepare it exactly how we wanted it for dinner. That’s the level of care on offer here. You won’t find this place on Google — walk all the way up the main street past Two Ducks, then Yule at the very top. Khuntea and Hadrien’s place is next on the left. Ring the bell if it looks closed.

Best atmosphere: The Hornbill Guesthouse

One morning we got breakfast at The Hornbill Guesthouse and felt like we’d stumbled into someone’s particularly hospitable home. No printed menu — the staff came out and told us what they had. We got pancakes made to order with a choice of toppings, and muesli with fruit and yogurt for the gluten-free option, with genuinely good coffee.

The atmosphere is easy and friendly, with hammock swings out front and a shelf of board games inside. A good place to spend an afternoon if you want somewhere that isn’t the beach — or a spot to sit with a coffee and let the day go by.

Best for an evening meal: The Sultan’s Kitchen

The Sultan’s Kitchen was still relatively new when we were there — two tables in the sand, an open kitchen with green lights and good music, a menu of skewers, kebabs, and hummus. It’s not the cheapest option on the strip, but the food is genuinely good and the portions are substantial. Sorry — no photos. We got into the food too much to think about it.

What to know before you arrive

There are no ATMs on Koh Rong Sanloem

This catches people out every week. There is no ATM anywhere on the island, and almost no establishment accepts cards. You need to arrive with enough USD cash to cover your entire stay. Read the full guide on getting cash on Koh Rong for what to do if you run short — there are options, but they involve hassle.

Bioluminescent plankton

M’Pai Bay is one of the better spots on the island for bioluminescent plankton — microscopic organisms that glow blue-green when disturbed in the water at night. The most common species responsible in Southeast Asian coastal waters is Noctiluca scintillans, which blooms in warm, calm, nutrient-rich conditions. Swim after dark, move your arms, and the water around you lights up. The effect is strongest in darker months (September–November), when moon interference is lower. Go in when it’s dark, away from the lights of the village.

The Clear Water Bay hike

The reason many travellers choose M’Pai Bay over Saracen Bay is access to the Clear Water Bay hike — a 5km trail through jungle and coastline to the most isolated and arguably most beautiful beach on the island. The guide on how to get to Clear Water Bay covers the route step by step, what to bring, and when to go. Start early, bring water, and wear proper shoes.

Things to do beyond eating and sleeping

For a full list of activities on the island — snorkelling spots, the bioluminescent plankton bay, night kayaking, and what to know about the different beaches — see the things to do on Koh Rong Sanloem guide. M’Pai Bay is a starting point, not the whole island — Saracen Bay and Lazy Beach are worth a day trip each.

Frequently asked questions about M’Pai Bay

What is M’Pai Bay like?

M’Pai Bay is a small backpacker village on the northwestern tip of Koh Rong Sanloem. It has one main street with a handful of hostels, guesthouses, restaurants, and bars. The beach is modest in size but west-facing, with excellent sunsets. It’s significantly quieter and more budget-focused than Saracen Bay, and the vibe is social and relaxed — the kind of place where you intend to stay two nights and end up staying ten.

Is M’Pai Bay better than Saracen Bay?

It depends what you’re looking for. Saracen Bay is larger, more developed, has better infrastructure, and suits anyone who wants a conventional beach holiday. M’Pai Bay is smaller, cheaper, more communal, and is the base for the Clear Water Bay hike and bioluminescent plankton swimming. If you’re a solo backpacker or want a more off-the-beaten-track experience: M’Pai Bay. If you’re a couple who want a nice beach with good restaurants and mid-range hotels: Saracen Bay.

How do you get to M’Pai Bay?

Ferries to Koh Rong Sanloem depart from Sihanoukville port. Some services stop at M’Pai Bay pier directly; others dock at Saracen Bay first, requiring a short water taxi hop. The crossing takes around 45 minutes. Multiple companies run the route daily in dry season. Buy tickets at the port or book in advance during peak season (December–February).

Is it safe to swim at M’Pai Bay?

Yes, the water at M’Pai Bay is calm and safe for swimming in dry season (November–May). The bay is sheltered. The best snorkelling is at the rocky northern end near The Cliff Hostel, where the steps give direct access to the reef. Avoid the water during the monsoon months (June–October) when conditions can become unpredictable.

Can you snorkel at M’Pai Bay?

Yes — the rocky shoreline at the northern end of the bay, accessible via the steps at The Cliff Hostel, is the best snorkelling spot. The visibility is good in dry season and there’s more marine life around the rocks than on the sandy beach section. Bring your own mask and fins, or hire from a rental shop in the village.
