Free entry to all national parks for National Park Week
Entrance fees will be waived at all 392 national parks April 17-25 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 nps.gov/npweek/.

Events include hikes, wildlife programs and heritage celebrations around the country.
A number of parks have special events for kids scheduled for April 24, which is National Junior Ranger Day. Kids who participate in walks, litter pick-ups, and other activities can earn a junior ranger patch.
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.
But a few hotels and other park concessionaires are offering special promotions in conjunction with National Park Week. Offers for coupons, merchandise discounts, freebies and two nights-for-one lodging deals, are listed at parkpartners.org/Special-Offers-for 2010.html
