These fee-free days provide a great opportunity to visit a new place or an old favorite, especially one of the national parks that normally charge an entrance fee. The entrance fee waiver for fee-free days does not cover amenity or user fees for activities such as camping, boat launches, transportation, or special tours.
Please check with each park for operating hours and event schedules.
