Mekong Sunset or City Lights River Cruise Phnom Penh

Sisowath Quay and the riverside pier

The cruise leaves from the riverfront along Sisowath Quay, the tree-lined promenade that runs for several kilometres beside the Tonle Sap. In the late afternoon it fills with families, joggers and street vendors, and the colonial-era buildings opposite house cafés and restaurants with river views.

Your tuk-tuk ride from the hotel takes about 10 minutes through the city centre, a fun introduction to Phnom Penh's busy streets and markets. Pickup for the sunset cruise is between 4:15 and 4:30 PM, and for the city lights cruise around 6:30 PM. After the cruise you make your own way back; tuk-tuks wait along the quay and ride apps are inexpensive and quick.

The Royal Palace seen from the water

The highlight for many guests is the view of the Royal Palace, built in the 1860s when the capital moved to Phnom Penh. From the river you see the tiered golden roofs and slender spires of the Throne Hall and the Moonlight Pavilion rising above the walls, framed by palm trees and the flags along the quay.

In the soft evening light the palace roofs seem to glow, and after dark they are floodlit in gold. The Silver Pagoda, famous for its floor of silver tiles, stands in the same complex. If you plan to visit the Royal Palace during the day, note that it is open in the morning and afternoon and requires covered shoulders and knees.

Chaktomuk, where the rivers meet

Just off the palace lies Chaktomuk, the Four Faces, where the Tonle Sap joins the Mekong and the Bassac branches away to the south. The confluence is so wide that it feels like a lake, and the boat turns slowly here so you can take in the scale of the water and the low green banks across the river.

This meeting point explains one of the natural wonders of Cambodia: in the rainy season the Mekong rises so high that it pushes the Tonle Sap backwards, reversing its flow and filling the great lake to the north. On the far banks you see stilted riverside houses and small wooden fishing boats, a glimpse of rural life only minutes from the capital.

Diamond Island and the modern skyline

Heading downstream, the boat passes Koh Pich, or Diamond Island, a new district of apartment towers, event halls and promenades linked to the city by bridges that light up in colour at night. Nearby, a giant Cambodian flag flies over the riverfront and makes a classic photograph from the deck.

Phnom Penh's skyline has grown fast over the last decade, and from the water you see old pagodas, colonial facades and glass towers side by side. Is a Phnom Penh river cruise worth it? It is one of the easiest and most relaxing ways to understand how the city has grown around its rivers, and a gentle way to spend the first or last evening of a trip to Cambodia.

Sunset cruise or city lights cruise

The 5 PM sunset cruise is timed for the golden hour, when the sun sets behind the city and colours the sky over the Tonle Sap. This is the best time for photographs and for watching river life as fishermen return and the promenade fills with people.

The 7 PM city lights cruise leaves after dark, when the Royal Palace, the riverside and the bridges are illuminated and the air is cooler. Both cruises last about one and a half hours, have an open upper deck and a covered lower deck, and offer snacks and soft drinks for purchase on board. The best time of year for a river cruise is November to April, the dry season.
