This starts as Upper Santa Ysabel Truck trail, after 1.5 miles it forks. The left fork is Black Mountain Truck Trail. It leads to the summit of Black Mountain. Long ago there was a forest fire lookout tower at the summit. That has been removed, but the road remains. It is occasionally maintained, but generally requires a truck, jeep, bicycle, or a lot of walking to reach the top. From valley floor to end of tail is about a three thousand foot climb---with almost no descending (maybe 10 feet down) along the way---a real, unrelenting workout. The grade is mostly moderate, eight to ten percent. But a little more than a mile from top is a section locals refer to as "the wall", because after almost six miles of unrelenting climb you are faced with a quarter mile of 15-25% grade! After which there is a small semi-shaded area where you can rest (or ride slow circles if you want to claim a nonstop climb) before climbing another fairly steep (10-15%) over the last mile. On a clear afternoon, you can see: the sun reflecting off the ocean 30 miles to the west; the Palomar Observatory dome to the northwest, San Jacinto Mountains to the north, Cuyamaca Peak to the east, and Ramona to the south. And more reward for the climb---three thousand feet uninterrupted descending in seven miles.
