Modjeska and Santiago Peaks Loop via Maple Springs

This 22.5-mile loop begins at Maple Springs Trailhead and traverses the high ridges of the Santa Ana Mountains, including Modjeska Peak and Santiago Peak, the two tallest summits in Orange County. The route combines singletrack, dirt roads, and fire roads, offering steep climbs, exposed ridges, and expansive views of Orange County, the Pacific Ocean, and inland valleys. This is a strenuous, full-day hike or a multi-day backpack option for experienced hikers or trail runners seeking long mileage and significant elevation gain.

The loop begins on Maple Springs Trailhead, climbing steadily to connect with Silverado Motorway, a wide fire road that carries you higher into the Santa Ana Mountains. From there, continue along North Main Divide Road, which offers open ridges and scenic overlooks.

The trail ascends to Modjeska Peak, providing panoramic views of Santiago Peak to the north, Orange County to the west, and Inland Empire valleys to the east. From Modjeska, follow the ridgeline to Santiago Peak, where the summit offers sweeping vistas of the surrounding mountains, forests, and the Pacific coastline.

The return route descends via Maple Springs Road, reconnecting with Maple Springs Trailhead, completing the loop. Along the way, hikers experience a mix of shaded oak woodlands, chaparral-covered slopes, and exposed ridge lines.

Flora & Fauna

• Flora: Chaparral species such as chamise, manzanita, and scrub oak dominate the slopes. Oak woodlands provide shade in lower areas. Spring wildflowers include lupine, monkeyflower, and poppies.

• Fauna: Mule deer, coyotes, bobcats, red-tailed hawks, and occasional rattlesnakes. Smaller wildlife includes lizards and ground squirrels.

Permits

• No permits are required for day hiking in this section of Cleveland National Forest.

• Fall is also good, with cooler temps and clearer skies.

• Summer is very hot with minimal shade; early starts and plenty of water are essential.

Need to Know

• Total elevation gain is significant; this is a strenuous route requiring good fitness.

• Water is scarce; carry enough for the entire loop.

• Trails and roads are well-marked but a map or GPS is recommended.
