The best running trails in San Bernardino National Forest

The San Jacinto Peak via Round Valley Trail offers an unforgettable jogging experience, taking you through diverse terrain from lush pine forests and meadows to exposed alpine environments. You'll start with a gentle climb towards Round Valley, then tackle the steep ascent to Wellman Divide, before reaching the 10,834-foot San Jacinto Peak summit. From the top, prepare for truly spectacular 360-degree panoramic views that stretch across the Pacific Ocean, the Los Angeles Basin, and even parts of Mexico and Arizona on a clear day.

This difficult 10.0-mile (16.0 km) route, with its 2407 feet (734 metres) of elevation gain, is typically completed in about 2 hours and 21 minutes, making it a serious workout for experienced joggers. Access is primarily via the Palm Springs Aerial Tramway, which quickly transports you from the desert floor to an alpine setting. Remember that free day-use wilderness permits are required from the Long Valley Ranger Station, and you should be prepared for high altitude conditions and potentially much colder weather at the summit.

What makes this one of the popular jogging routes in San Jacinto State Park is its dramatic elevation change and the unique "Island in the Sky" experience, rapidly ascending from desert to alpine. The region is a lofty haven of forests and meadows, offering a stark contrast to the desert below. Just be mindful of the Mount San Jacinto State Park permits required and the potential for heavy snow and harsh conditions during winter months.

If you're seeking a truly rewarding challenge, the Suicide Rock via Deer Springs Trail delivers a difficult 6.7-mile (10.8 km) jogging experience, climbing 1850 feet (564 metres) in roughly 1 hour and 33 minutes. The route begins among oak trees, quickly transitioning to diverse pine forests and massive Manzanita bushes as you ascend. You'll navigate varied terrain, from dirt paths to rocky sections and even soft pine needle cushioned single track, all leading to the spectacular panoramic views from Suicide Rock itself.

Planning your visit requires a bit of foresight; you'll need to secure a free wilderness permit from a ranger station before you start. Be aware that dogs are not permitted on this trail, as it crosses into Mount San Jacinto State Park Wilderness. Given the strenuous nature and significant elevation gain, ensure you're well-prepared with water and appropriate gear, especially if you're tackling this popular trail in the Idyllwild area.

Beyond the physical challenge and stunning vistas, Suicide Rock holds a rich history, tied to a Cahuilla Native American legend about two lovers. The area is also a hotspot for rock climbing and offers excellent opportunities for wildlife and bird viewing within the San Bernardino National Forest. It's a fantastic option for experienced joggers looking for a trail with both natural beauty and cultural significance.

The Ernie Maxwell Scenic Trail offers a dynamic jogging experience through diverse forest types, from oak and pine to manzanita, providing a shaded escape. As you navigate the singletrack dirt path, which can be narrow and rocky in places, you'll be treated to stunning vistas of the San Jacinto Mountains, including iconic formations like Tahquitz Peak and Suicide Rock. This route is a rewarding challenge for those who appreciate mountain scenery and varied terrain.

To access the trail, head to Humber Park, which serves as the main trailhead and parking area. While the trail is generally accessible year-round, spring and early summer are ideal for spotting wildflowers, and fall offers beautiful foliage. Be aware that winter conditions may bring snow, and always plan to carry sufficient water for this demanding route.

Beyond its natural beauty, the Ernie Maxwell Scenic Trail holds historical significance, named after Ernie Maxwell, an advocate for the outdoors and founder of the Idyllwild Town Crier. It's a popular choice not just for jogging, but also for hiking and horseback riding, known for its well-maintained conditions and dog-friendly policy, making it a beloved local gem.
