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.

Along the Visitor's Center Loop Trail at Mission Trails Regional Park, you'll come across beautiful views and an exciting journey for mountain bikers. Be sure to wear waterproof shoes as creek crossings can get you slightly wet!

The Steele Canyon Bridge, also known as the Sweetwater River Bridge, is a beautiful landmark crossing the Sweetwater River. It is on the National Register of Historic places, and is no longer used for vehicles but is a great hiking, running or biking spot.

River crossing near the Visitor's Center. Can be nearly dry or full of storm runoff, depending on the season. It's a nice bit of water in an otherwise dry area.
