Entrance fees will be waived at all 392 national parks from now through April 25 for National Park Week.
Many parks have organized events, talks, volunteer clean-ups and other projects to encourage the public to visit that week. Details, including a “Find a Park” search option, are at www.nps.gov/npweek.
Some park areas and roads are still off-limits to the public this early in the season, and not all services and concessions are open.
