Phou Khao Khouay National Protected Area (NPA) covers an area of 2.000 km2 in Bolikhamxay and Vientiane Province has excellent evergreen, mixed decidous and coniferous forests in addition to extensive fire-clima grasslands which support key species that include wild elephants, white-cheeked gibbons and green peafowl. A commuity managed elephant watching tower in Ban Na provides one of the best opportunities to view large wildlife in Laos. One can take nature walks with village guides through the park's old growth forests and well-known waterfalls-Tad Leu, Tad Xay and Tad Xang. Self-guided walks are also available from the visitor center at Tad Leuk which has camping facilities and tents for rent. Nam Kading NPA is abundant with wildlife dueits low population density and biologically diverse forest ecology. Elephant, gaur, giant muntjac, gibbon, the sooty babbler, rufous-throated fulvetta, river lapwing, wreathed and great hombills and large otters are just some of the many species that inhabit the area. One of the country's most extensive wetland systems is located southwest of Pakxan town and is known to have a very unique and abundant population of migratory birds. The wetlands can be reached by motorbike or truck via a number of dirt trails leaving town. Also of interest is the natural cool springs along the Nam Mang River, a pleasant site for swimming and picnicking.
