Far removed from the bustling summer crowds meandering up the Mount Adams South Route, High Camp offers remarkable views of Mount Adams's glaciated north side and expansive alpine meadows in every direction. Beginning at the popular (and often dusty) Killen Creek Trailhead #113, you’ll quickly find yourself immersed in a subalpine land of summer wildflowers. At around 2.5 miles you’ll cross East Fork Adams Creek and its lush meadows; this is also a good opportunity to fill up on water. Note that in later summer it may be increasingly difficult to source water, so it’s a good idea to bring plenty for your trip. The tree line will begin to thin as you reach the PCT, and a steeper climb begins across rocky terrain to High Camp at the edge of Adams Glacier.
Secluded backcountry camping opportunities are abundant even during busy weekends, and the area rarely feels crowded. In addition to the rugged glaciers at High Camp, there is a good chance you’ll see marmots, herds of mountain goats, and depending on the weather, unimpeded views of nearby Mount St. Helens, Mount Rainier, and Goat Rocks. In early summer the snow levels may make it difficult to locate the trail, so it’s recommended that you hike with both compass and map. If you plan to hike above 7,000 feet you'll need to obtain a Cascade Volcanoes Pass.
