Alila Koh Russey Guide 2026: Cambodia Island Stay

Why Koh Russey Is Different From the Rest of the Cambodian Coast

Koh Russey (often written Koh Ruessei and nicknamed Bamboo Island) sits in Ream Bay, a short distance off the mainland east of Sihanoukville and close to Ream National Park. That location matters. Islands like Koh Rong and Koh Rong Samloem involve a longer ferry crossing from Sihanoukville, while Koh Russey is close enough that the transfer feels like a scenic extension of the drive rather than a separate journey.

The island itself is small and low-lying, with a sandy shoreline, casuarina and coconut palms and calm, shallow water on the sheltered side. It is not a party island and has no village nightlife to speak of. For most guests that is precisely the point: you trade choice for quiet, and the resort becomes the entire experience.

If you want to compare the wider coastline before choosing, our overview of the best luxury island resorts on the Cambodia coast places Koh Russey alongside Koh Rong, Koh Rong Samloem and the private-island options further out.

Rooms and Villas: Which Category to Book

Alila Koh Russey is a mid-sized resort by regional standards, with a mix of suites and villas rather than hundreds of identical rooms. The design leans on Alila’s signature: natural timber, stone, neutral tones, generous glazing toward the sea and an emphasis on outdoor living space.

Suites

The suite categories suit travellers who plan to spend most of the day at the main pool, the beach or the spa. They are the value entry point and still feel spacious compared with typical city hotel rooms.

Pool villas

The villas with private plunge or lap pools are the reason many couples pick this resort. A private pool changes the rhythm of a stay in Cambodia’s heat: you can swim at midday without walking to the main pool, and evenings feel genuinely private. Families with one young child often find a villa works better than two connected rooms.

Larger multi-bedroom options

For multigenerational groups, check whether multi-bedroom villas are available for your dates. Inventory is limited, so these are the first to sell out around Christmas, New Year and Khmer New Year in April.

Our practical advice: if the price gap between a suite and an entry pool villa is modest for your dates, the villa usually delivers the bigger upgrade in day-to-day enjoyment.

Getting There: Flights, Roads and the Boat Transfer

The journey has become much simpler in recent years. The Phnom Penh–Sihanoukville expressway cut the road trip from the capital substantially, and international and domestic flights into Sihanouk International Airport put the coast within reach without a long drive at all.

1. Fly into Phnom Penh or Siem Reap as part of a wider Cambodia trip.
2. Continue to the coast either by private car on the expressway or with a domestic flight to Sihanoukville when schedules suit.
3. Drive to the resort’s mainland jetty in the Ream area — the resort arranges this as part of its transfer.
4. Take the short boat ride across to Koh Russey.

Ask the resort to coordinate the full chain when you book. Arriving after dark is possible, but the boat crossing is far more pleasant in daylight, and sea conditions are calmer in the dry season. Check the latest entry rules and the official Cambodia e-Visa portal before you fly.

Best Time to Visit Koh Russey

Cambodia’s south coast follows a clear dry-and-wet pattern. The months you choose affect sea clarity, transfer comfort and price far more than any room upgrade will.

What to Do: Spa, Water and Day Trips

Most stays are deliberately slow. Expect to divide time between the beach, the infinity-style main pool and the spa, where treatments draw on Southeast Asian techniques and local ingredients.

• Kayaking and paddleboarding in the sheltered bay are best in the early morning before the wind picks up.
• Snorkelling around nearby islets is pleasant in the dry season, though do not expect Raja Ampat-level reefs.
• Ream National Park on the mainland offers mangroves, boat trips and birdlife for a half day off the island.
• Kampot and Kep are realistic day trips by car for pepper farms, the crab market and colonial-era architecture — our guide to luxury resorts in Kep covers the area if you want to split your stay.

Yoga and wellness sessions are usually on the programme; confirm the current schedule on arrival, as activities vary by season and occupancy.

Dining on a Small Island

On any single-resort island, the dining programme is the experience you cannot escape, so it matters. Alila Koh Russey has a small number of venues covering all-day dining, a more relaxed beachside option and a bar for sunset. Khmer dishes are worth ordering: fish amok, Kampot pepper crab and green-mango salads tend to be the highlights rather than international comfort food.

Because there is no outside restaurant scene, stays of more than four nights can start to feel repetitive. Two strategies help. First, look for half-board or credit-inclusive packages, which usually work out cheaper than paying à la carte. Second, plan one mainland lunch in Kep or Kampot to break up the week.

Dietary requirements are generally handled well, but notify the resort in advance — ingredients arrive by boat, so last-minute specialist requests are harder.

Cost Planning and Booking Strategy

Rates move sharply with the calendar. Peak-season pool villa nights around the festive period can cost several times a wet-season suite. Rather than quote prices that will be outdated in weeks, here is how the cost structure typically breaks down:

• Room or villa: the largest share; pool villas carry a clear premium.
• Transfers: usually charged per person or per vehicle and boat — confirm whether they are included.
• Meals: island pricing applies; packages often save money.
• Spa and excursions: optional but easy to overspend on during longer stays.

Booking through Hyatt’s own channels can earn and use World of Hyatt points, which makes Alila Koh Russey a popular redemption. Compare that against packages from specialist agents that bundle transfers and dining. Before travelling, read our guide to travel insurance for Southeast Asia islands, especially for boat transfers and medical evacuation cover.

Who Should Choose Alila Koh Russey — and Who Should Not

This resort works brilliantly for a specific kind of trip and less well for others.

If you want a more remote, private-island feeling, compare the options in our Koh Rong and Koh Rong Samloem resorts guide. If you prefer wild landscapes over polished design, the Koh Kong luxury guide covers the Cardamom Coast tented camps.

Key Takeaways

• Visit December–April for calm crossings, clear water and the most reliable sunshine.
• Book a pool villa if the price gap is modest — the private pool transforms midday heat.
• Let the resort arrange the full transfer chain and aim for a daylight boat crossing.
• Choose half-board or credit packages; there is no outside dining on the island.
• Plan 3–4 nights, with one mainland day trip to Kep, Kampot or Ream National Park.
• Pair it with Siem Reap and Phnom Penh for a balanced Cambodia itinerary.

Final Thoughts

Alila Koh Russey is the easiest luxury island stay in Cambodia to get right: close to the mainland, calm, design-led and suited to rest after a busy cultural itinerary. Time it for the dry season, book a pool villa if your budget allows, and treat it as a restorative finale rather than an activity-packed beach holiday.
