Getting There -- U.S. 93, which runs between Las Vegas and Kingman and long ran across the top of Hoover Dam, connects Nevada and Arizona via the Colorado River Dam, which opened in late 2010. On either side of the river, small secondary roads lead to various marinas on Lake Mead, and there are also many miles of unpaved roads within the recreation area. If you have a high-clearance or four-wheel-drive vehicle, these roads can take you to some of the least visited shores of the two lakes.

Visitor Information -- For information, contact the Lake Mead National Recreation Area, 601 Nevada Way, Boulder City, NV 89005 (tel. 702/293-8906; www.nps.gov/lame), or stop by the Alan Bible Visitor Center (tel. 702/293-8990), between Hoover Dam and Boulder City.
