The 5.8-mile trek along the Pacific Crest Trail into Jefferson Park is one of Oregon’s most coveted hikes. Both the journey and the destination are truly spectacular.
Jefferson Park is a flat basin at the bottom of Mount Jefferson’s north side. It’s a lush valley situated in a protected bowl with the glaciated stratovolcano on one side and the 6,900-foot Jefferson Ridge on the other. Known for its stunning display of wildflowers in late summer and its numerous subalpine lakes, the park captivates outdoor enthusiasts of all types, be they PCT through-hikers, casual explorers, or photographers hoping to snap the perfect shot.
Access into Jefferson Park can be gained either from the north via Jefferson Ridge, the trailhead at Breitenbush Lake, or from the west via Sentinel Hills and NF-2243 (also roughly 5.8 miles one-way).
When accessing the park from the north there are basically two schools of thought:
As an alternate route, consider the roughly 2-mile detour that ascends to the top of 6,095-foot Pyramid Butte. The old Skyline Trail can be difficult to find, but views from the top of this jagged outcropping are worth the additional mileage. When considered independently, the climb to the top of Pyramid Butte makes for a relatively easy, 3.4 mile round-trip day hike.
Note: If you are driving in from Olallie Lake, note that the section of road between Horseshoe and Breitenbush Lake (roughly 2 miles) is very rough, and a high clearance, four-wheel drive vehicle is recommend. Further, backcountry camping within 250 feet of Jefferson Park’s lakes is only permitted at signed, designated campsites.
