Porcupine Flat Campground, situated at 8,100 feet in Yosemite National Park, offers a primitive camping experience along Tioga Road. It provides access to hiking and backpacking trails such as Lukens Lake and the Grand Canyon of the Tuolumne, with Porcupine Creek serving as the only water source. Due to narrow roads and primitive conditions, RVs and trailers are not recommended, and reservations are required when open, typically from late June to mid-October.
