This is a strenuous and very technical 16.2 mile loop with a 1500' gain/loss. It is a long climb on a good fire road; with some of the best single track in the range. There is no water, and the area is popular with hunters, so come prepared. Getting there: Take Ave D (Hwy 138) west approximately 25 miles from Hwy 14. Look for the Old Ridge Route Road (about 5 miles east of the Hwy 138/ Interstate 5 junction) and turn left on Old Ridge Route Rd. Drive uphill on 8N04, a paved road for 2.6 miles to the ruins of Sandbergs Resort on the right and park here. Route: Proceed south on 8N04 Rd 2.6 miles where you intersect with 7N23. The sign on the left reads Castaic 25 mi., Sawmill Campground 14 mi. Turn hard left on 7N23. The first mile is the toughest uphill but it gets easier after that! At 3.2 miles keep left bypassing 7N22. At 6.5 mL you reach a summit and it flattens out for a while. At 7.8 miles a short rocky climb brings you over the top. At 9.8 miles a double track takes off to the left. This path leads to Horse Camp Cyn 17W01. Down this jeep road 0.1 mile is a fence and a sign that reads Bear Camp 2 mi., Burnt Peak Junction 10 mi., Wilderness Camp 1.0 mi, Oakdale Cyn Rd. 5 mi. (The Pacific Crest Trail, which incorporates 17W01 from here to Horse Camp Cyn is closed to bicycle traffic). To pick out Golden Eagle Trail, follow the fence line to the left and it will open to a good trail. The trail will cross 7N23 at 10.6 mi., 11.8 mi, and 13.7 mi. If the trail gets too bushy you can exit onto 7N23 at any of these crossings and enjoy the downhill back to the parking spot!
