A short 5.18 miles connector trail between the Gibraltar Resivour and the Cold Spring Trail. This trail makes for a great mountain bike ride or day hike. A very large rock formation of Temblor Sandstone was called The Rock of Gibraltar. When Santa Barbara needed more drinking water, they constructed the dam backing up the river water to form the Gibraltar Reservoir. A short distance down stream from the dam a tunnel was dug under the Santa Ynez Mountains to Mission Canyon to provide river water to the city. Over the years a large part of the upper portion of the reservoir has filled in with sand and silt. It now supports a dense stand of willow and cottonwood trees..
The dam was raised to increase its holding capacity and was recently strengthened to protect it from a possible earthquake action. It is located just south of the Little Pine Fault that crosses the center portion of the lake.
