Old Growth Lane

Old Growth Lane is a short mountain biking route in Millersylvania Memorial State Park in Washington, managed by State Park and Recreation. The route is an out-and-back that starts and ends at nearly the same elevation, with a high point of 258 feet and a low of 248 feet. It is about 0.44 miles long and has no elevation gain, so it works as a quick stop or a warm-up before heading to other trails in the park. 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 roughly 20 days a month. Fen Way Boardwalk, a mountain biking route, is just 0.1 mile away, and the Maple Hollow Loop and The Loop hikes are both within a third of a mile. For more riding, Bentley Trail is about 0.6 mile off.
