"An ascent of Charleston Peak is considered to be the ultimate experience in the Spring Mountains by many. The well-engineered and well-maintained 20-mile Mt. Charleston National Recreation Trail, divided into the North Loop and South Loop trails, provides an excellent route to the 11,918-foot summit, which towers over the surrounding terrain by as much as 10,000 feet, offering extraordinary views across southern Nevada, southeastern California, and northwestern Arizona. The route as described below begins from the North Loop trailhead with a steep, nearly 3-mile ascent, followed by a lengthy journey along the crest of the range, and then a steep 4-mile descent to the South Loop trailhead.
On the upper slopes of Charleston Peak, summiteers pass above timberline into an alpine-like zone, where only ground-hugging plants can survive the arid, windy conditions. The vegetation within the Spring Mountains is unique, as the range contains nearly forty endemic species, the highest number of any range in the entire Great Basin."
