King-Castle Trail #4326


Beginning at King's Castle Trailhead, King Castle Trail #4326 travels south and east up the northern and eastern side of Castle Rock. The trail meanders uphill over several streams and through an old growth coniferous rainforest. The trail switches back in some steep sections, climbing to and crossing Forest Road 480 before heading west and ending at Castle Rock Trail #3506.

When combined with other trails in the area, the O’Leary Trail Complex makes for a world class mountain biking trail. The trail is a 22 mile, single-track loop with an intense backcountry feel. The IMBA has designated it an ‘Epic Ride,’ a ride that is “technically and physically challenging, more than 80 percent single track and at least 20 miles in length.”
