Spider Rock Campground is located in a wooded area of the Tse Ho Tso Plateau in the park. It's smaller than Cottonwood Campground, with about 30 sites total, so if you're looking for a quieter, more private experience, this is the place to go.
Although this is a dry campground, meaning no hookups, there is potable water, a dump station, and toilets. Additionally, the hosts have installed quite a few new features into this campground - you'll have access to WiFi, a place to buy snacks and cold sodas, and solar showers. Generators are allowed from 7 am to 10 pm. If, for some reason, you're sick of your RV, there are also options to rent tents or a stay in a hogan, a traditional Navajo dwelling.
The campground is located in a flat, grazing area for wildlife, so your pets are welcome only on leash. Because Canyon de Chelly is a sacred and significant area for the Navajo Tribe, hiking and backpacking the canyon is only allowed from Spider Rock Campground. The campground is usually first come, first served, but for the summer months, it would be wise to reserve a spot ahead of time. You can book tours with the campground host or head out on the hike that starts at the campground and leads you along the canyon rim.
