Free
No entrance pass required
An entrance pass is not required to access Fossil Butte National Monument. Other National Park Service sites may require an entrance pass or fee. Depending on your trip plans, an interagency pass may save you money. 2026 Free Entrance Days in the National ParksCome experience the national parks! All National Park Service sites that charge an entrance fee will offer free admission to everyone (other fees, including timed entry or reservation fees, may apply). Mark your calendar for these entrance fee-free dates:
Beginning in 2026, free entrance on these days will be for US citizens and residents only. Nonresidents will pay the regular entrance fee and any applicable nonresident fees.
Fossil Butte National Monument no longer issues the free interagency passes. The Bureau of Land Management (BLM) office in Kemmerer, WY issues these passes.
