Notes

On June 20, 2025, the Washington State Department of Natural Resources announced the opening of new trails at the Olsen Creek State Forest in Whatcom County. There are now seven miles of trails for hiking, mountain biking, and horseback riding.

The DNR says the trails offer stunning views of Lake Whatcom, Bellingham Bay, and the Canadian Cascades on clear days. Parking is limited at the Y Road Trailhead, and you don’t need a Discover Pass here. But keep in mind that this is a new DNR trail system, so a future trailhead parking location might require the pass.

Safety Tip

Hiking with Children

Teach kids what to do if they get lost or separated from the group. They should hug a tree near an open area and stay put. They should also know how to signal for help. And more!
