2. Yosemite National Park (California)
Spanning nearly 1,200 square miles of gorgeous deep valleys, beautiful meadows, giant sequoias, unusual rock formations, and breathe-taking waterfalls, Yosemite is a nature-lover’s paradise. Dogs are allowed in developed areas, on fully paved roads, sidewalks, along bike paths (except for when signed), and in campgrounds (except for walk-in campgrounds). Your pup must be on a leash no more than six feet long at all times and may not be left unattended. Pets are not allowed on trails, in undeveloped wilderness areas, in public buildings, on shuttle buses, in lodging areas, and in other areas as signed. Yosemite offers a kennel from late June through Labor Day weekend.
