How to Hike This Trail Safely
Hiking the Bumpass Hell Trail involves risk. Learn more about general hiking safely in this high-elevation and remote park. Special considerations for this trail include:
- Shade is limited on this trail. Hikers are encouraged to wear or bring a hat and carry water.
- Winter conditions can persist through the summer months, especially in the forested sections of the trail. Wear proper footwear (good tread, ankle support, closed toe) and consider using trekking poles to help maintain balance. Knee and ankle injuries are the most common visitor injury in the park.
- Stay on established trails and boardwalks in/around the basin. Ground in hydrothermal areas can look solid but may actually be a thin crust hiding pools of acidic boiling water or mud. Visitors have been severely injured by traveling off-trail in these areas.
- Water and mud in hydrothermal areas is acidic. Do not put water or mud from park hydrothermal areas on your skin. Even water that is cool to the touch is acidic and can irritate or burn your skin with prolonged exposure.
- Hiking at high elevation can aggravate preexisting medical conditions. Know the effects of altitude. Carry plenty of water, take often, and do not exceed your abilities.
