At Yosemite National Park, pets on a leash no longer than 6 feet are only allowed in developed areas; on fully paved roads, sidewalks, and bicycle paths (except when signed as not allowing pets); and in all campgrounds except walk-in campgrounds (e.g., Camp 4) and in group campsites. There are a few additional (very obscure and unsigned) places where pets are allowed: Wawona – Wawona Meadow Loop, Chowchilla Mountain Road, and Four Mile and Eleven Mile fire roads (but not the Four Mile Trail in Yosemite Valley); Hodgdon Meadow – Carlon Road from the trailhead to Hodgdon Meadow and on the Old Big Oak Flat Road from Hodgdon Meadow to Tuolumne Grove parking lot. Pets are not permitted on trails, including the trail to Vernal Fall (however, pets are allowed on the Wawona Meadow Loop); on unplowed roads covered in snow; in undeveloped and wilderness areas; in public buildings; on shuttle buses; in lodging areas; in all walk-in and group campgrounds/campsites, including Camp 4; and in any other areas, as signed. There are no exceptions to these pet regulations for carried pets (in arms, carriers, strollers, backpacks, etc.) in the areas of the park where pets are not allowed.
