The National Park Service manages the Lake Mead National Recreation Area where visitors will find a plethora of outdoor activities including hiking, fishing, boating, diving, and swimming, as well as biking, and four-wheel driving. The Lake Mead National Recreation Area is well serviced by marinas and tour companies. The large paddle wheel boat, Desert Princess, cruises the lake daily. At 112 miles long, the lake is the largest reservoir in the United States. It doesn’t take long to get here; head east about 30 miles from the center of Las Vegas through Henderson. If you plan on boating, be sure to check the water depth levels as they fluctuate throughout the year and can change dramatically year over year. The Lake Mead National Recreation Area is open all year round.
