San Juan Hill

Embark on a challenging hike through Chino Hills State Park, combining San Juan Hill, Faultline Trail, North Ridge Trail, and Gilman Peak. This difficult route spans 13.9 miles (22.4 km) and involves a significant elevation gain of 2223 feet (678 metres). You can expect to spend around 6 hours and 38 minutes traversing varied terrain, from rolling hills to open fields, with panoramic 360-degree views from the summits of San Juan Hill and Gilman Peak that can stretch to Catalina Island and Big Bear on clear days.

When planning your visit, be aware that the trails are largely exposed, offering minimal shade, especially during warmer months. The high clay content in the soil means paths can become slippery after rain, so check conditions before you go. The park may also close trails during periods of extreme fire danger, making it essential to verify current access and safety information.

This extensive loop offers a deep dive into the natural beauty of the region. In spring, the landscape often bursts with vibrant wildflowers and mustard blooms, adding a colorful dimension to your journey. The route provides a unique opportunity to experience the diverse ecosystems and expansive vistas that make Chino Hills State Park a notable destination for hikers seeking a demanding and rewarding outdoor adventure.
