Mount Mars
About
Mount Mars is a summit of 2,665 feet in the Silver Peak Wilderness, part of the Monterey Ranger District of Los Padres National Forest in California. The nearest town is Fort Hunter Liggett, about 14 miles away. Summer and early fall are the most comfortable times to go. Typical averages from a nearby weather station at Hearst Castle show highs around 75 to 78°F from July through September, with almost no wet days. That station sits well below the summit, so temperatures up high run cooler. The Mount Mars Southeast Ridge Usetrail starts just 0.1 mile from the summit. Salmon Creek and Spruce Creek are each about 0.9 mile away, and the Nacimiento River, a paddling route, lies roughly 8 miles off.
