Muang Long is a small market town with a backdrop of limestone cliffs plunging down to the riverside. Two rivers run side by side, the Nam Long and the Nam Ma, which is reddish in colour and at the base of the cliffs. The Nam Long, for which the town was named, is closer in and more accessible for exploration.

The heart of Muang Long is the market. While the building that holds it is lovely, the market itself is not as interesting as that in Muang Sing. Busy in the mornings with a stream of traditionally dressed people from local villages, by afternoon there is little of interest to see and little delicious food to be found. One of the major highlights, however, is the small shop selling locally made handicrafts.

Muang Long is slated by some to be the next Muang Sing, with great potential for trekking and mountain biking in the area which has lovely scenery, cliffs, jungle and interesting villages. Tourism in Muang Long is not as organised as in Muang Sing, Luang Nam Tha and Vieng Poukha. Most people simply transit through on their way to Xieng Kok, so Muang Long is the perfect destination if you'd like to spend time exploring where other tourists rarely stay.
