Gifford Pinchot National Forest campground near Trout Lake with 30 sites in a scenic meadow-edge setting, popular for berry picking and Bigfoot Country exploration.
Peterson Prairie Campground sits at 2,900 feet near Trout Lake in the southern Gifford Pinchot National Forest, in an area famously called "Bigfoot Country" by locals. The 30 sites accommodate RVs up to 32 feet in a forested meadow-edge setting. Huckleberry picking in late summer is legendary here, and the area offers hiking to nearby lava tubes and the Indian Heaven Wilderness. Vault toilets and potable water are on site.
Peterson Prairie sits in a high meadow of the Gifford Pinchot National Forest with commanding views of Mount Adams — Washington's second-highest peak at 12,281 feet — and access to the Indian Heaven Wilderness, a high-altitude plateau studded with over 150 huckleberry-ringed lakes. The Indian Heaven area is one of the most significant traditional gathering sites for tribal nations of the Columbia Plateau, who gathered annually to harvest huckleberries that still grow in extraordinary abundance across the volcanic meadows. Ice Cave, just 3 miles from camp, is a lava tube where year-round ice persists in the upper chambers — a remnant of a volcanic eruption that created an underground cave system insulated from summer heat by the thick basalt walls.
Practical guidance assembled from current operator maps, park pages, and clearly identified community observations.
The Guler Ice Cave (1 mile from camp) is the main draw — lava tube ice cave accessible June through September when ice forms naturally. Loop B has pull-through sites for equestrian campers. The meadow setting is beautiful and the huckleberry fields in late summer are exceptional. Book early when the Ice Caves are open. Bring warm layers — the high elevation meadow is cooler than the Columbia River corridor below.
