The Gales Creek Trail from the Gales Creek Trailhead and Campground area to its peak at Bell Camp Road offers a steady climb on great singletrack through a classic Pacific Coast forest. The climb is never too steep to be enjoyable except for maybe the last meters near the top. The return back to trailhead offers a fun and fast descent. Also, when the other MTB trails in the area are too wet to be enjoyable this trail is popular almost year-round as it drains well and dries out fast.
