The trails bordering Sweetwater Reservoir are mostly smooth dirt paths. Most of the intersections are marked, but the lesser used trails get overgrown at times. As you run closer to San Miguel Mountain, the trails get progressively rockier, steeper, and much more technical. All of the trails are pretty open with views of the reservoir and foothills nearly the entire time.

There is a small network of dirt and wood chip trails and gravel service roads circling around the Upper Otay Reservoir. This little lake is much smaller than its lower counterpart, but it is no less beautiful. A lot of the trails are in the trees, but some sections open up in meadows and have views across the water and of nearby mountains. This is a really runnable trail when there hasn't been recent heavy rains.
