A dirt pull-off area on the south side of E. Lake Mead Blvd (NV 147) provides access to an overlook. The path is badly littered, the interpretative geology signs vandalized, and the smog makes for challenging photography, but maybe worth a stop if you're heading east early in the morning.

Las Vegas from Sunrise Mountain
White Rock Canyon, a moderate hike to the Colorado River south of Hoover Dam, is also the land access to Arizona Hot Springs.

Colorado River at the Mouth of White Rock Canyon
The mouth of Arizona Hot Springs canyon is a short but obscure hike southward along the Colorado River from the mouth of White Rock Canyon. (Boaters have a sandy beach right at the mouth of the Springs canyon.) The hike up canyon is also short, but more physically challenging. You'll get wetter, but warmer, as you proceed to the hot pools.

The mouth of Grapevine Canyon, a dirt road drive from the highway and a short hike in, contains the densest petroglyth panels I have seen.

Petroglyths at Grapevine Canyon
Mojave National Preserve, about 1.5 hours southwest of LV, features a rich variety of desert environments. Paved and bladed roads make much of the hiking, camping, sightseeing, and wildlife accessible without an SUV. At this time of year, I found the desert in bloom, the Joshua trees in flower, and the desert tortoises active.

Kelso Dunes
Desert National Wildlife Refuge is located in the Mojave north of LV, with three 4WD access points off Highways 93 and 95. Visitors are on their own and should be well researched and equipped for the backcountry. This year's forays were scouting trips for future expeditions.

Recovering Yucca Forest - Mormon Well Road
Pahranagat National Wildlife Refuge is an oasis of lakes along Highway 93 about 80 miles north of LV. Birding, camping, and native rock art are its principal offerings, but it also contains a 4WD access into the Desert National Wildlife Refuge.

Upper Lake
The "Dunes" are more like badlands and the "Recreation Area" is a power toy playground.

Power Toy Tracks
Red Rock Canyon National Conservation Area is <1 hr. outside of Las Vegas. It features a scenic loop drive and hikes of various lengths and challenges.

View Coming Out of Icebox Canyon
Valley of Fire State Park is ~1 hr. outside of LV, with scenic drives and short hikes featuring unique scenery and native American petroglyphs. Popular Hollywood 'alien planet' landscape. Spectacular at sunrise/sunset.
