Overview

Lost Lake Campground is adjacent to Highway 20 near the summit of Santiam Pass in the Willamette National Forest. This campground is not Lost Lake Resort in the Mt. Hood National Forest. This rustic campground is located on the west shore of shallow Lost Lake. The water level of the lake fluctuates seasonally and is quite low in summer with water loving willows crowding the marshy shallows of the lake. This is a popular spot during fishing and hunting seasons.

This campground has 15 single campsites. Trailers are not recommended at this location. There are picnic tables, fire rings, and three single vault toilets. No drinking water is available.

Campfires allowed until and unless otherwise posted. Fire bans are common during summer months. Please plan accordingly.
