The Sierra Bike Trail occupies a sliver of land between active Metrolink commuter rail tracks and Sierra Highway, connecting the communities of Palmdale and Lancaster in California's Antelope Valley. The path helps commuters access two Metrolink train stations—one in each city—and also provides a recreational route for residents.
There is a short gap that can be bridged via bike lanes between 6th Street East and Avenue Q around the Palmdale Metrolink station. The trail is landscaped to provide some greenery in the desert surroundings, and some benches can be found along the route. Make sure you bring water, though—the trail is located on the western edge of the Mojave Desert, and the beating sun can be vicious.
Free parking is available at the Palmdale Transportation Center (39000 Clock Tower Plaza Drive) in Palmdale.
