Description

Viewed from the south, it is clear why Castle Peak was named. A massive fortress, Castle Peak stands alone (except for Basin Peak) commanding an awe inspiring view.

The summit has long been a destination for skiers in the Donner Pass area. The scenery from the summit is outrageous — beyond the Donner Summit area you can see north to Sierra Buttes and south to the peaks of Desolation Valley. In addition to the scenery, the bowl to the northwest of the summit attracts telemark skiers. Be aware that this bowl and many of the slopes in the vicinity of Castle Peak are unsafe when unstable snow conditions prevail.

The tour to the summit of Castle Peak is a combination of two distinct parts. First there is the modest climb to Castle Pass and then there is the steep ascent to the peak (1200 feet in 1.2 miles).

Castle Peak is one of several popular destinations for those spending a night or two at nearby Peter Grubb Hut.
