Great view of Sweetwater Reservoir, a 960-acre man-made lake formed by the Sweetwater Dam.

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 view from this section of the bikeway is stunning. The vibrant green and blue colors of the water and skyline are breathtaking and worthy of a stop to take some incredible photos.

This is a great place to learn about water safety and operating small watercraft. The bike path goes right past the center, but the path is elevated and fenced off. The easiest way to get to the aquatic center is via the pedestrian tunnel on the other side of the highway. There are tables outside that make for a nice picnic spot.

The Sweetwater River starts high in the Cuyamaca Mountains. The name "Sweetwater" originates from the olden days when people would generally refer to a fresh water river as a sweet water river due to the taste of the water. Along side the river is the Sweetwater Bikeway which is a shared bike path. It can get fairly busy at times, especially on the weekends, so be mindful of other path users.
