Toy Pass [A](3) pages 346-347]
Southeast Ridge from Toy Pass, Class 1-2
At the top of Toy Pass, just south of the cattleguard, a 4WD/ATV road leaves the main road and heads west through the junipers. Follow this road west as it quickly contours to a ridge above the next drainage where there is a gate. Cross through the gate. From this point, the road swings around the drainage to saddle on the main crest. After this point the road drops downhill heading to God knows where. There is a range fence in the saddle. This fence leads along the ridge to Peak 6499. You can cross through a gate at the saddle and follow the ridge toward Peak 6499 or you can follow the fence line on its south side. Eventually, if you stay south of the fence, you will come to an ATV trail designated C310. This ATV trail runs nearly over the summit of Peak 6499. The ATV trail has several ups and downs that will lengthen the ordeal.
Alternatively, if you go through the gate you can stay near the ridge top following the occasional cattle trail and avoid a few ups and downs but you will need to cross the fence without a gate before reaching Peak 6499. My route measured 3.4 miles with 483 feet of gain. If you start at Toy Pass add another mile and 200 feet of gain.
