Wellman Divide

Embark on a dramatic journey through multiple climate zones on the San Jacinto Peak and Round Valley Loop. You'll traverse dense pine forests and meadows in Round Valley, where wildflowers bloom in spring, before ascending to exposed, rocky terrain. The highlight is undoubtedly the summit of San Jacinto Peak, offering spectacular 360-degree panoramic views of the Coachella Valley, Salton Sea, and distant mountain ranges.

This difficult 7.6-mile (12.2 km) hike involves a substantial 2433 feet (741 metres) of elevation gain, taking approximately 3 hours and 58 minutes. Access is typically via the Palm Springs Aerial Tramway, which significantly reduces the initial climb. Remember that a free day-use wilderness permit is required beyond the Long Valley Ranger Station, and high altitude can be a factor, so plan accordingly.

What makes this trail truly notable is the dramatic transition from desert landscapes to alpine wilderness in a single day, especially when using the tram. The area is part of the Mount San Jacinto State Park, a high-elevation wilderness offering a cool escape from the desert heat. Keep an eye out for wildlife like mule deer and mountain chickadees, and appreciate the historical significance of the CCC-built cabin near the peak.

The San Jacinto Peak via Devil's Slide Trail offers a dramatic ascent into the San Jacinto Wilderness, starting amidst dense pine forests and transitioning to rugged, rocky terrain. You'll navigate numerous switchbacks on the Devil's Slide Trail, eventually reaching Saddle Junction before the final, boulder-strewn push to the 10,834-foot summit. The reward for this difficult 7.5-mile (12.0 km) hike, with its 4221 feet (1286 metres) of elevation gain, is an expansive panorama that can stretch all the way to the Pacific Ocean and Catalina Island.

To tackle this approximately 4-hour and 30-minute journey, you'll need a day-use permit from the Idyllwild Ranger Station, especially if you're hiking on a weekend between Memorial Day and Labor Day when permits for the Devil's Slide Trail are limited. Parking at Humber Park also requires an Adventure Pass. Always check for seasonal conditions, as snow and ice can persist at higher elevations, making winter hiking on San Jacinto Peak via Devil's Slide Trail a different challenge.

This route is a significant access point into the San Jacinto Wilderness from Idyllwild, offering a prime way to experience Southern California's alpine beauty. Along the way, you'll intersect with the iconic Pacific Crest Trail, and near the summit, an emergency hut provides shelter. It's considered a good first major mountain for those with solid fitness, showcasing a unique blend of forest, meadows, and dramatic granite topography.
