Staying near the Grand Canyon is easy. Staying in the Grand Canyon? Not so much. In fact, Phantom Ranch is the only lodging available below the canyon rim. This unique accommodation can trace its roots back to Native American pit houses dating back nearly 1,000 years that were found on the site, which more recently served as a camp for President Theodore Roosevelt during a hunting expedition. Currently, it offers cabins, dorm-style rooms — separated by gender — a restaurant, a ranger station, and a beach, as well as classic native stone and wood architecture. You can only get there by mule, on foot, or in a raft, but not to worry — you need to make reservations up to a year in advance, so it's not like you'd be randomly dropping in, anyway.
