Responsible visitation & Leave No Trace
- Know before you go

- Stay on trail
- Many points of interest sit in fragile ecosystems. Stick to marked paths to protect vegetation and prevent erosion.
- Respect wildlife
- Observe from a distance, never feed wildlife, and give nesting birds and denning mammals plenty of space.
- Pack it in, pack it out
- Take all trash, food scraps, and gear back with you. Remote sites often have no trash service.
- Leave what you find
- Don't take rocks, plants, fossils, or artifacts. Federal law protects cultural and natural resources on public land.
