Spanning 1.3 million acres along the western slopes of Washington’s Cascade Range, Gifford Pinchot National Forest offers a dramatic volcanic landscape shaped by fire and ice. Established in 1908 and named for America’s first professional forester, this protected wilderness stretches 72 miles from Mount Rainier National Park south to the Columbia River, encompassing two of the Pacific Northwest’s most iconic peaks: Mount Adams (12,276 feet) and Mount St. Helens.
The forest’s diverse terrain includes ancient old-growth groves, alpine meadows blanketed in wildflowers, active glaciers, and the stark, regenerating blast zone around Mount St. Helens. Hikers can explore hundreds of miles of trails, from easy riverside walks to challenging summit climbs. Anglers will find excellent opportunities in the forest’s many streams and lakes, while 35 developed campgrounds—including Blue Lake Creek, Horseshoe Lake, and Tillicum—provide bases for extended exploration.
The main access point is near Amboy, Washington, with Forest Road 25 and other scenic byways penetrating deep into the backcountry. Summer months (June through September) offer the most accessible conditions, with snow-free trails and open campgrounds. Spring brings rushing waterfalls and emerging wildflowers, while fall showcases brilliant foliage against volcanic peaks.
Winter transforms the forest into a snow-covered wilderness, closing many roads but opening possibilities for snowshoeing and cross-country skiing. Rangers recommend checking current conditions before visiting, as volcanic terrain and seasonal weather can affect trail access.
