A Chico classic, the North Rim Loop (sometimes referred to as Upper Bidwell Trail)—traversing North Rim Trail, B-Trail, and Yahi Trail—offers a little bit of everything that makes Bidwell Park so special: swimming holes for summer dips, springtime wildflowers, wild animals, and more. The length, rocky terrain, and elevation loss and gain make this a difficult trail, but first-timers to Chico should still put this on their “Must Visit” list. (Just keep an eye out for mountain bikers racing down B-Trail!). To get from B-Trail to Yahi Trail, you’ll need to briefly follow Upper Park Road.
Those still working on building their mileage can shave off a little time and distance by starting at Horseshoe Lake instead of Lot B. You can also shave off the end of the Yahi Trail by cutting over to Upper Park Road closer to the B-Trail at Lot S near Browns Hole.
