Manaslu trekking was officially opened to tourists in 1991, but mountaineering expeditions have long had access to the area. In 1950 a party led by HW Tilman trekked from Thonje to Bimtang and Colonel Jimmy Roberts crossed the Larkya La looking for an interesting mountain to climb. Manaslu (8156m.) was attempted by Japanese expeditions every year from 1952 until 1956, when the first ascent was made. It thus became known as a 'Japanese mountain', and much of the information about the area was available only in Japanese. The Japanese continued to dominate the climbing scene on Manaslu until 1971.
Though the Larkya La is a difficult pass, the trek around Manaslu is one of the harder in Nepal. In many places the walls of the Budhi Gandaki valley are perpendicular, so you cannot walk along the bottom of the valley. There is a huge amount of wasted climbing involved during the first part of the trek as you climb up and down over ridges or onto shelves to bypass cliffs. The trail is rough and steep and it often literally hangs on a bluff high above the river. The trek is remote and has no rescue facilities or opportunities to bail out if you are tired. There is only one facility that might conceivably be called a trekkers' hotel, and there are few English signboards between Arughat and Tilje.
