The Manaslu region offers a variety of trekking options. The popular Manaslu trekking route of 177 kilometres, skirts the Manaslu massif over the pass down to Annapurna. The Nepalese Government only permitted trekking of this circuit in 1991. The trekking trail follows an ancient salt-trading route along the Burhi Gandak River. En route, 10 peaks over 6,500 metres (21,300 ft) are visible, including a few over 7,000 metres (23,000 ft). The highest point reached along the trek route is the Larkya La at an elevation of 5,106 metres (16,752 ft). As of May 2008, the mountain has been climbed 297 times with 53 fatalities. The Manaslu Conservation Area has been established with the primary objective of achieving conservation and sustainable management of the delimited area, which includes Manaslu.
