The Sirindhorn Dam is another important multi-purpose dam in the Northeast.  It blocks Lam Dom Noi in Phibun Mangsahan District (about 70 kilometres from the city centre) on Highway 217. Turn right at Kilometre 71 for about 500 metres.  The area is a plain with a thicket on the hills surrounding the reservoir.  Guest houses are available for visitors.  More information may be obtained from the Electricity Generating Authority of Thailand, Bang Kruai, Nonthaburi, Tel. 436-3271-2.

Bo Nam bun (Bun Spring) is on Highway 217 about 700 metres from Sirindhorn Dam.  It is similar to a hot spring in terms of its appearance, but the water from this spring is of normal temperature and the water comes up from the ground.  It was discovered by a monk who was on a pilgrimage, and so a religious center, called Wat Nam Bun, was established.

Chong Mek Border, the boundary between Thailand and Laos marks the end of Highway 217, which is 89 kilometres long.  This highway will be connected to a 38 kilometre road in Laos leading to Pak Sae, which is a part of the Asian Highway.
