The Sweetwater River Trail in the Sunnyside area east of Bonita was changed considerably when the South Bay Expressway was built through the area.
On June 5, 2008, I road my mountain bike on the Sweetwater River Trail, and some other trails and roads in and near Sweetwater Summit County Park.
To save money, I parked my truck on San Miguel Road. There is a small fee for parking at the county park.
The plotted data do not fit the topographic map very well; I don't know the reason for this. The map may be a little bit off scale.
