Several trails on Laboratory property will remain closed due to safety or environmental reasons:
- Hidden Canyon Trail
- Deadman Crossing Trail
- Devaney/Longmire Trail
- Mortendad Bench Trail
- Mortendad Canyon Trail
Some Laboratory trails are open to the public whereas others are only open to Laboratory badge holders. Some trails allow dogs, horses, and bicycles while these are prohibited on other trails. It is your responsibility to understand the rules of a particular trail.
Trails are open from dawn to dusk, however trails and trail segments shown in red on trail maps are closed to all entry.
Hike open trails at your own risk; carry water, and beware of weather conditions, hazards, and wildlife.
Please leave no trace and pack out your trash.
