Melungtse was off limits to climbing until quite recently. The first attempt was made in Oct 1982 when Bill Denz made a strictly illegal attempt on the southeast ridge, after sneaking over the border from Nepal's Rolwaling Valley. However he turned back while still low on the route. In 1987 and 1988 Chris Bonington led two expeditions, with the second one succeeding in putting Andy Fanshawe and Alan Hinkes on the west summit, but did not climb the main summit. Another attempt in 1990, this time on the East Ridge of the main summit, failed well below the top.
