Mount Harwood via Register Ridge

Mount Harwood via Register Ridge is a doozy! This 5.9-mile out-and-back route, located within the San Gabriel Mountains, includes over 3,500 feet of elevation gain, making it an excellent choice for anyone seeking a steep, challenging mountain hike. This rugged trail provides stunning panoramic views, diverse terrain, and a sense of accomplishment upon reaching the summit of Mount Harwood. Although the Mount Baldy area is a popular destination for hikers, trail runners, and backpackers, this route takes the path less traveled and offers opportunities for solitude.

DESCRIPTION
The route begins from the trailhead at Manker Flats Campground, where street parking is available. It starts with a winding dirt road passing the scenic San Antonio Falls. Look for the turnoff on your left for the Baldy Bowl Trail. You’ll begin by climbing the singletrack trail, passing the trail register, and soon start your steep climb up Register Ridge. Make sure to bring a map or familiarize yourself with the route, as the Register Ridge Trail is not well-marked. However, once you begin hiking, the path is fairly obvious.

The Register Ridge provides excellent vantage points to view the surrounding peaks and valleys and offers a chance to take a break from the challenge of the climb.

Eventually, the Register Ridge Trail joins The Devil’s Backbone Trail. Turn left at the junction and continue for a brief section before turning right to ascend the final push to the top of Mount Harwood.

The final ascent to Mount Harwood offers breathtaking panoramic views, including vistas of the San Bernardino Mountains and the distant desert landscapes. The summit of Mount Harwood provides a well-deserved reward with its expansive views and a sense of accomplishment. Be sure to save your energy, as a route this steep is almost as challenging on the way down as it is on the way up.

Flora and Fauna:

• Flora: The lower elevations feature chaparral and mixed forests, including oak, pine, and manzanita. As you climb higher, you’ll encounter alpine flora such as mountain mahogany and various wildflowers, including lupine and Indian paintbrush.

• Fauna: The area is home to a variety of wildlife, including black bears, mule deer, and golden-mantled ground squirrels. If you’re lucky, you may even see the elusive bighorn sheep.

SAFETY AND CONSIDERATIONS

• Some sections involve steeper climbs with rocky terrain and some scrambling.

• The trail is less defined in places, requiring careful navigation.

• Carry plenty of water, as there are limited sources along the trail. Be sure to filter or treat any water collected from natural sources.
