A compact pairing of two completely different Cambodias: Angkor compressed into one packed day by bicycle (for those who have already seen the temples or prefer not to stretch the cultural program) and four days on the Koh Rong archipelago — snow-white beaches by day and surf glowing with plankton at night. The route is a family one, with more emphasis on water and beaches than on history.
The logic of the route: one dense day in Siem Reap by bicycle — the three main temples without excess stretching, then a flight to the sea and a boat to the Koh Rong archipelago with two islands of different character: lively Koh Rong with the snow-white Long Beach and the night glow of the water, and its quiet neighbor Koh Rong Sanloem with almost deserted bays.

Check-in and Acclimatization
After arrival — check in and a light program: tomorrow will be busy, so it’s worth conserving your energy today. The hotel is 10–15 minutes from the center, convenient for both an evening stroll and an early start tomorrow.
Pub Street
The main evening street of the city, closed to cars as the sun sets — live music, street food, bars with a wide selection of Angkor craft and local beer.
Night Market
Near Pub Street — souvenirs, textiles, spices alongside street food. A good place to buy light clothing for tomorrow’s cycling trip in the heat if you didn't bring any with you.
One-Day Ticket
A single Angkor Park pass costs $37 for adults for one day; children under 12 enter free with a passport. You can purchase it at the Angkor Enterprise ticket office at the park entrance or online in advance – they take your photo directly for the ticket.
Three Temples by Bike
Angkor Wat at sunrise, then Bayon with its 216 stone faces in Angkor Thom, and finishing with Ta Prohm, a temple embraced by tree roots. The bike route is about 20–25 km per day – a hot and physically demanding format, but it gives you the freedom to move at your own pace between points without waiting for a tuk-tuk.
Water, Sunscreen, Early Start
With this packed itinerary in the heat, plenty of water, a hat, and sunscreen are essential. It's smart to start as early as possible to complete most of the route before the midday heat.
1 / 2 Siem Reap to Sihanoukville Flight
Around 1 hour of flight time – noticeably faster than the overland journey, which would take most of the day. Upon arrival, a direct transfer to the port — be sure to check the boat schedule in advance, as the last departures are usually no later than late afternoon.
Sihanoukville Port
The departure point for Koh Rong – speedboats run several times a day, with journey time to the main island taking around 45 minutes – 1 hour depending on your specific destination.
First Evening at Sea
After two busy days in Siem Reap — it’s time to switch to relaxation mode: check-in on the island, dinner by the sea, and a first glimpse of the archipelago that will be home for the next few days.
Long Beach by Day
One of the most beautiful beaches in the archipelago – several kilometers of white sand and turquoise water with almost no buildings along the coastline. During the day, enjoy swimming, snorkeling near the nearby reefs, and beach bars in designated areas of the beach.
Glowing Plankton at Night
From November to May, on moonless nights and away from artificial light – the water near the shore begins to glow with a bluish luminescence with every movement (wave, paddle, step in the water). The best spots are Long Set Beach and Coconut Beach; boat tours specifically for this phenomenon cost around $10 per person, it’s worth going out after sunset, around 7:00 PM or later.
Planning According to the Lunar Calendar
The effect is noticeably brighter during a new moon and in darkness – if that's a priority for your trip, you should check the dates of your tour against the lunar calendar in advance, rather than relying on the general “November–May” season.
Crossing to the Neighboring Island
Just 20–30 minutes by boat separate lively Koh Rong from the much quieter Sanloem – the contrast is immediately noticeable: fewer buildings, almost no evening buzz, and on many beaches you can find yourself practically alone on a weekday.
Saracen Bay Beach
One of the most peaceful beaches in the archipelago - fine white sand, a gentle slope into the water, which is especially convenient with children. The infrastructure is minimalist: a couple of bungalow-cafes, no large hotel complexes.
Lambaada Bay
An even more secluded spot on the island – you can reach it by foot through the forest or by boat, and the reward is a practically deserted beach even in high season.
Boat to the Mainland
Allow at least 3–4 hours for your return transfer from the islands to Sihanoukville before your flight: boat schedules can be delayed in the shoulder season due to sea conditions.
Route Summary
6 days — one packed day of temples and four days exploring the diverse islands of Koh Rong archipelago, from parties to complete seclusion. Practical tips for this trip are in the postscript below.
Off the Beaten Path Notes
The plankton doesn't glow with equal brightness every night – it depends on the lunar phase. We didn’t tie the date to a new moon calendar in advance and saw the effect, but noticeably weaker than in photos online. If this is your key goal for the trip, check the lunar calendar when planning dates, rather than relying on "roughly November–May."
One Day in Angkor – A Conscious Compromise
Three temples (Angkor Wat, Bayon, Ta Prohm) by bicycle in one day is a marathon, not a leisurely stroll: around 20–25 km in the heat between locations. We chose this format knowingly, knowing that the main focus of the trip was the sea, not the temples; if Angkor is your priority, it's wiser to take a route with three days dedicated solely to the temples.
Ko Rong vs Ko Rong-Sanloem – Different Pace on Neighboring Islands
Just 20–30 minutes by boat separates lively Ko Rong with bars and parties at Long Beach from quiet Sanloem, where there might be five people on the entire beach. It would have been better to distribute the nights differently—start with the noisy island, end with a quiet one, rather than the opposite, so that the vacation ends with tranquility, not a sharp contrast back to the hustle and bustle.
Beach Bungalows – Book in Advance During High Season
On Sanloem, infrastructure is modest, there are few good bungalows—during high season (December–February) they’re snapped up 2–3 weeks in advance. Booking on arrival without a reservation can leave you with no options or paying over the odds for what's left.
Actual Budget
For a family of three (2 adults + child), excluding international airfare: accommodation – around RUB 33,000 for the entire route (including a private villa on Ko Rong), transport (domestic flight + boats between islands) – RUB 16,000, food – RUB 17,000, Angkor ticket and plankton boat tour – RUB 13,000. Total approximately RUB 79,000—matched the initial estimate.
