Trail Conditions

Season for Summer/Fall Hiking Trails: June - October

This page is updated as snow begins to melt from trails, generally starting as early as April or as late as June.

If looking to explore the park during the months of November - May, which usually involves winter conditions, please refer to the Oversnow Route Conditions page, which gives ideas for recreation in winter or spring. Most hiking trails remain snow-covered into May/June and sometimes July. Trails are not cleared of winter snow accumulation. Trails melt out naturally.

When selecting a trail, please consider:

  • Pets are not permitted on park trails, including in carriers.
  • Trail conditions are updated when available. We welcome your trail reports by email to lavo_information@nps.gov.
  • Many trails are not accessible until the highway or road is cleared of snow in the spring. View the status of roads or spring road clearing operations (March - June).
  • Hiking in the park involves risk. Learn more about reducing risk when hiking at high-elevation in a remote area.
  • View oversnow route conditions for recreation in winter or spring. Snow recreation is best approximately November through April.
  • Bumpass Hell Trail is closed each winter and typically does not open for hiking until June/July.
