Entrance fees and passes

The National Park Service lists no entrance fee for Civil War Defenses of Washington[1]. Some tours, campgrounds or permits inside a park can still have their own fees.

When to visit and hours

Hours depend on which site you visit, because different NPS parks manage the grounds. The sites run by Rock Creek Park, such as Fort Stevens and Fort Reno, are open daily from dawn to dusk[3]. The sites run by National Capital Parks East, such as Fort Dupont and Fort Foote, open at 6:00 am and close at 10:00 pm each day[4]. George Washington Memorial Parkway manages Fort Marcy, which keeps hours of 6 am to 10 pm each day[5]. NPS suggests checking the weather forecast for each individual site[6].

Pets and dogs

Under the NPS pet rule, a pet in an area where pets are permitted has to stay in a crate or cage or on a leash of six feet or less[7]. The rule keeps pets out of public buildings, public transportation and designated swimming beaches, and service animals are excepted[7]. NPS marks pets as permitted on 4 of the 5 things to do it lists for this park[8]. Each park can close more areas to pets[7].

Fees and hours are what NPS lists in its data at the snapshot date. They change: tell readers to confirm on the official park page before a trip. Visits are NPS recreation visits (counted entries, not unique people). Use them only for this park's own months and years, never to rank parks. Campground list and site counts come from NPS and Recreation.gov records. Count fields can differ slightly between the two. The pet rule is the national baseline (36 CFR 2.15). The park may close more areas to pets. Do not claim specific trails allow dogs unless a fact says so.
