Lost Lake Group Site is located in Lost Lake Campground which is situated on the northern edge of Lost Lake on the Tonasket Ranger District of the Okanogan-Wenatchee National Forest. Set beneath mixed-conifer forest and surrounded by mountains, this campground offers one group site, suitable for large family and group camping excursions as well as several non-reservable single and double sites.
Lost Lake Campground offers outdoor enthusiasts the opportunity to hike, fish, and enjoy a long list of outdoor recreational activities. Anglers enjoy boat fishing (with an electric motor only) for rainbow and triploid eastern brook are available in abundance. A boat ramp is available in the campground. For an easy, interpretive hike for the whole family, the Big Tree Trail starts across the road from the Lost Lake guard house at the entrance to the campground. This 0.8 mile trail connects with a loop trail that highlights two 600-year old western larch trees. It is particularly beautiful when the wildflowers are out in June. Another great hike is the Strawberry Mt. Trail that starts just outside the Campground entrance and travels 1.5 miles up to Strawberry Mt.
This campground has one designated group site, able to accommodate up to 100 people. The site is equipped with picnic tables, campfire rings, grills, drinking water and flush toilets. Access to Lost Lake beach and Lost Lake Amphitheater are within walking distance.
The Lost Lake area offers a medium sized lake with scenic views, forested mountains, abundant wildlife, and a few hiking trails. Visitors to the area can expect many days of warm, sunny weather in the summer, and winters with clear skies and plenty of snow. The surrounding area has clean streams and diverse forests that support an abundance of wildlife, including deer, porcupine, black bear, cougar, native fish, common loon, bald eagles, and migratory birds. Endangered and threatened species, including gray wolves and Canada lynx, also find havens in nearby ecosystems.
