Alva, a serene town in northwest Oklahoma, offers quiet camping retreats next to unique state-park landscapes. Salt Plains State Park is 40 minutes from town and made up of salt-crusted plains—campers can dig for selenite crystals while here. The park's campgrounds, located near Salt Fork River, provide water and electric hookups for RVs as well as tent sites with access to fishing and birdwatching areas—look out for the rare whooping crane. Alabaster Caverns State Park, the largest natural gypsum cave in the world that’s open to the public, invites adventurers to explore more underground marvels. Above ground, camping options include RV sites with electrical hookups and primitive tent sites set amid the rugged landscape. Little Sahara State Park, known for its vast dunes resembling a miniature desert, offers an unparalleled off-roading experience. Stay nearby at a local RV park with pull-through sites and full hookups as well as three cabin rentals and a few motorhome rentals too. The campground also has direct access to the park’s ATV trails.
