Jimbilnan Wilderness, wilderness area in Nevada
Jimbilnan Wilderness is a large protected area in southern Nevada with volcanic mountains, deep canyons, and wide open spaces. The terrain varies between rocky slopes, gentler rolling hills, and white gypsum hillsides that slope gradually toward nearby Lake Mead.
Volcanic eruptions millions of years ago shaped the mountains and rocks, creating black basalt flows and colored volcanic stone. The Hamblin-Cleopatra Volcano was split apart by tectonic forces, with its pieces now sitting miles away from each other.
Jimbilnan Wilderness is mainly a place for outdoor activities with few human-made structures, where visitors experience quiet and observe wildlife in their natural state. The small nearby town of Overton serves as a starting point for excursions into this untouched landscape.
There are no visitor centers or developed facilities, so bring water, sturdy shoes, and a map. The area is accessible by boat from Lake Mead or by high-clearance vehicle via Boathouse Cove Road, roughly 40 miles from Las Vegas.
The name Jimbilnan comes from a local Native American language and likely means 'the place where the wind blows strongly', which visitors experience through constant breezes. The area hosts unique plants like Palmer's Phacelia and desert trumpet adapted to salty gypsum soils found nowhere else in the region.
