Yes, camping is allowed in Monument Valley. There are several campgrounds in and around the area, including The View Campground, which offers both tent and RV camping with spectacular views of the valley. There are also private campgrounds on Navajo land that offer unique experiences, such as desert and cave camping options. Please note that camping outside of designated campgrounds is not allowed, as most of the land in Monument Valley is part of the Navajo Nation and requires proper permits and permissions.
