If you're looking for a hike that showcases the best of Upper Bidwell Park, the North Rim, B Trail, and Middle Trail Loop is a fantastic choice. This 9.9-mile (16.0 km) moderate loop takes about 4 hours and 27 minutes to complete, offering a journey through varied landscapes. You'll experience rocky climbs on the North Rim Trail with expansive views of the Sacramento Valley, then descend through winding paths on the B Trail, and finally navigate the rolling terrain of the Middle Trail, passing through areas dotted with valley oaks and manzanita trees.
Planning your visit is straightforward, as the trail is accessible year-round. However, for the most vibrant scenery, aim for spring when the hills are lush and wildflowers bloom. Be prepared for sun exposure on the North Rim Trail, as it offers little shade, so pack water and sun protection. While the B Trail is popular with mountain bikers, the intersections are generally marked, and dogs are permitted on a leash.
This loop is considered a Chico classic, encapsulating the diverse natural beauty of Bidwell Park. Beyond the scenic vistas, the area is known for its volcanic rock formations and opportunities for summer dips in swimming holes nearby. It's a great option for those seeking a substantial half-day hike with a mix of challenging ascents and enjoyable descents.
