Lake Mead National Recreation Area offers 1.5 million acres of mountains, canyons and two lakes, Lake Mead and Lake Mohave. Getting out on the water is the main draw here, though biking and hiking trails are also available. More than a dozen national park and concessionaire-run campgrounds offer around 900 tents and RV sites, including the convenient Boulder Beach Campground just minutes from Las Vegas. Campers can also enjoy vehicle, horseback, shoreline, and backcountry camping.
