Campbell Tree Grove Campground sits at 1,100 feet in Olympic National Forest's temperate rainforest near Humptulips, offering free camping beneath old-growth Douglas firs and hemlocks. The 10 well-separated sites accommodate tents and small RVs up to 16 feet, with vault toilets, fire rings, and picnic tables. There's no cell service or water on-site.
This rustic campground offers primitive camping options with 10 total sites, including 2 designated tent sites and 8 combined use sites. RV camping is limited to vehicles shorter than 16 feet.
Weather and SeasonsSpring is the sweet spot here. Daytime highs run 45–65°F, offering cooler, drier windows between the region's frequent storms. Waterfalls and creeks peak with snowmelt and winter runoff, wildflowers bloom, and migrating songbirds fill the canopy. Trails are less crowded than summer or fall. Pack rain gear and layers regardless of season. Mosquitoes and horseflies can be heavy; bring repellent.
ElevationSituated at varying elevations throughout the western slopes of the Olympic Mountains, the campground offers diverse perspectives of the rainforest ecosystem. From valley floors where massive Sitka spruces and western red cedars create cathedral-like groves, to hillside perches that reveal the stunning layered canopy stretching toward distant peaks. The gentle elevation changes provide accessible trails for all skill levels while showcasing how the forest transforms with altitude, from lush river valleys to the transition zones where rainforest meets mountain meadow.
Natural Features and SceneryAncient Douglas firs and western hemlocks tower overhead, their trunks wrapped in moss and lichen. The forest floor is thick with sword ferns, and fallen logs nurse new saplings in the damp understory. Streams flow through the area, fed by winter rains and spring snowmelt. Roosevelt elk, black bears, and varied thrush inhabit the surrounding forest. Spring brings waterfalls and creeks to their fullest volume.
