2020 Summer Conditions & Information

Campgrounds and popular trailheads are exceptionally busy this summer.

  • Most campsites are reservable this summer. First-come, first-served sites are limited. Learn more about camping.
  • Popular trailhead parking areas can fill up by mid-morning. This includes Bumpass Hell, Kings Creek Falls, and Hat Creek. Plan to arrive early and have one or more alternative trails if parking is unavailable. Trailheads with limited parking are identified with a [P] on the trail conditions page.
  • Bumpass Hell Trail is open and is extremely busy. Consider an alternative such as Sulphur Works or one of the numerous hikes to hydrothermal areas in the Warner Valley Area.
  • A closure on Manzanita Lake prohibits swimming, wading, and the use of soft-sided flotation devices. Hard-sided boats may be used on the lake except in an area along the eastern shore that is closed to all use.
  • Kayak rentals at Manzanita Lake are unavailable at this time.
  • Backpackers must obtain a free permit and carry a NPS-approved, bear-resistant container. Backpackers are highly encouraged to avoid camping in the Twin and Rainbow Lakes areas (accessed via Summit Lake Trailhead) due to numerous human-bear interactions this summer.
