The paths around Sweetwater Reservoir are primarily well-worn dirt, with most junctions clearly signed, though some of the less frequented routes can become overgrown. As you near San Miguel Mountain, the terrain becomes increasingly rugged and challenging, while open views of the reservoir and surrounding hills remain a constant backdrop.

The Sweetwater River Trail is an 8-mile loop trail that runs along both sides of the river. The trail has some elevation gain, but this gives you nice views of the nearby mountains.
