The Clark County Shooting Complex, located on the northern outskirts of the Las Vegas–North Las Vegas line in Nevada, is the largest shooting facility in the United States at 2,900 acres (1,200 ha). At full build out is anticipated that only 900 acres (360 ha) will be developed with the rest of the site serving as a buffer for the surrounding community. The park is located at the northern end of Decatur Boulevard at a traffic circle in unincorporated Clark County, just north of the City of Las Vegas boundary.

Skate and BMX park, sports fields and dog park. Includes the AMP, an outdoor amphitheater/ concert venue.
Though not regularly visited, this is actually the largest national wildlife refuge in the lower 48 states. Coincidentally, it overlies part of the Nevada Test Site, so you can't just wander too willy-nilly, although the latter is quite distant. But this refuge's visitor center and trails will introduce you to aspects of the Mojave Desert ecosystem that are framed by some rather tall desert peaks, with a chance to see bighorn sheep and other species and even a yucca forest if you hike far enough.
If time permits, and you don't mind watching a movie on your vacation, consider a visit to West Wind Drive-in; especially if visiting from out of the country where drive-ins are infrequent. And for an added bonus; it's normally a double-feature, so you get two movies for the price of one.
