A collection of popular Upper Bidwell Park trails, the North Rim‑B Trail-Middle Trail Loop will both push you and reward you. The North Rim Trail is a slow and rocky climb with great views to B Trail, which descends through many twists and turns among valley oaks and manzanita trees to the previously mentioned Middle Trail. You’ll walk along the Middle Trail for a little bit to get onto North Rim.
Modification: If you’re still building up strength and endurance, hike North Rim and Middle Trail individually over a couple of days — and then then come back to tackle the loop in its entirety. You can also shorten the loop by starting at Horseshoe Lake.
