Responsible visitation & Leave No Trace

Know before you go
Check the operator's site (BLM, NPS, state agency, or private owner) for access rules, permits, and seasonal closures before driving out.
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.
