Chaiyaburi Scenic Point

Chaiyaburi Scenic Point marks the spot where the Songkhram River meets the Mekong, at Ban Chaiyaburi in Tha Uthen district, about 25 km north of Nakhon Phanom city. The Songkhram runs a greenish tint against the Mekong’s usual muddy brown, and where the two currents meet the colour line is visible from the bank — Thai visitors know it as the maenam song si, the “two-colour river.” Entry is free.

The viewpoint itself is unassuming: a stretch of riverbank with a few shaded rest spots and food and drink vendors who set up in the evening, when locals come to eat with the confluence and the hills of Laos as a backdrop. There’s no ticket booth, no visitor centre, and no English signage — this is a local spot more than a curated tourist stop, and that’s part of its appeal. Longtail boats pass on the Mekong side, and the sound of the current is the main soundtrack once the vendors’ evening crowd thins out.

Insider Tip: Go in the late afternoon, when the vendor stalls are open and the light is easier for photographing the colour contrast than the flat glare of midday.

Watch out: There’s minimal shade during the day and no facilities to speak of — bring your own water if you’re visiting outside the evening food-vendor hours.

This is a quiet, low-key stop rather than a headline attraction — worth building into a wider loop of Tha Uthen’s riverside temples rather than a dedicated trip on its own. Pair it with Nakhon Phanom’s riverfront, or the nearby Bicycle Path along the Mekong River Nakhon Phanom for a longer look at this stretch of the river.
