Horn Gap Professional Review and Guide
"Ashland is 15 miles north of the California border on Interstate 5. Most of the climbing on the roads is moderately difficult, but there are a number of short, steep sections. These make the climb more demanding, but they quickly give way to less taxing segments. Horn Gap Trail is only 1.3 miles long, but it makes for a fun little climb and an exciting, twisting descent.
Novices may have difficulty with the trail's tight turns and short, moderately steep grades. Views of this ride are limited by the dense forest that lines the roads and trail. You can catch a glimpse of Mt. Ashland from Horn Gap Trail, or take an optional side trip on an old spur road to an open area. Here you get a view of grassy foothills to the north and east of Ashland, forested ridges to the southeast, and Mt. Ashland to the south."
