Lost Valley is a mountain biking route in Washington, managed by the State Department of Natural Resources and located about a mile from the nearest town. The ride is an out-and-back that covers roughly 2 miles, with a low point of about 950 feet and a high of about 1,100 feet. The climb is gentle, with a total elevation gain of about 120 feet. Summer is the most comfortable time to ride. Typical averages from a nearby weather station in Olympia show July and August highs around 78°F with only about five wet days a month, while winter brings highs in the mid-40s and rain on about 20 days a month. That station sits well below the route, so temperatures on the trail run cooler. Mima Falls West is just 0.1 mile away, and McKenny is about 0.4 mile off. For paddling, Sherman Creek and the MnM Trail are both about 0.9 mile away.
