Olympic Adventure Trail

The Olympic Adventure Trail (OAT) is a 25 mile alternative to the paved, rail grade ODT route between the Elwha River and Lake Crescent. It was built by the Clallam County Sheriff’s Chain Gang under the direction of Sgt. Jon Beltrami, and by the Thursday Crew of Clallam County volunteers under the direction of Lorrie Mittmann and Jim Mantor.

It is designed for mountain bikers, hikers, and equestrians. It has 25 miles of double and single track riding over very scenic, hilly, forested terrain. The trail is entirely off road except the last 4 miles on the west end, which is on old RR grade along the Lyre River and shared with logging access.
