The Bayview Trail Observation Deck β Red Hill Trailhead loop from Newark offers a dynamic gravel biking experience, blending flat, paved sections with challenging mixed-surface climbs. You'll pedal through marshlands and along creek-side paths, enjoying expansive views of the San Francisco Bay and surrounding hills. The highlight is undoubtedly the Bayview Trail Observation Deck, a perfect spot to pause and take in the scenery, before tackling the notable steep ups and downs of the Red Hill portion.
This moderate 15.6-mile (25.0 km) route, with 524 feet (160 metres) of elevation gain, typically takes about 1 hour and 23 minutes to complete. While much of the trail is accessible, the Red Hill section requires good fitness due to its challenging pitches on red sandstone and clay dirt. The loop is enjoyable year-round, but spring brings vibrant wildflowers to Coyote Hills Regional Park, enhancing the already beautiful landscape.
Part of the larger Coyote Hills Regional Park, this route immerses you in a diverse natural environment. Beyond the bay views, you might spot monarch butterflies during migration season, adding to the trail's appeal. The park's well-maintained paths and designated observation points make it a rewarding destination for those seeking a blend of natural beauty and a good workout on their gravel bike.
