May 26, 2025, Goldilocks Trail

One of the oldest mountain bike trails you'll ever ride, Goldilocks has been a go to spot for Bellingham riders for decades. However, this area is on private land and trail closures are not uncommon due to logging operations, so keep an eye out for trail updates.

Amazing trail. You can really pick up speed quick on this one. Defintely keep yourself controled. Took a super hard crash on this one once because I felt comfortable and just kept picking up speed before a root took me for a ride. Techy at the top with some amazing flow in the middle. Love the ending with the double drop.

Cyrus Gates Overlook is an overlook at the end of a 3.5-mile gravel road. There's a huge collection of stairs that descend to Lost Lake from the overlook if you want to lock up your bike and check out the lake.
