Annual Pass Regulations Discovery Park Welcome Discovery Park is where the American River meets the Sacramento River. One of Sacramento County's best boat launches gives recreational boaters a chance to explore both of Sacramento's wild and scenic rivers, while area fishing enthusiasts will admit that this is a favorite spot to find trout and salmon.
Families can dine in beachside picnic areas and watch the river flow by.
The park is located beside I-5 in downtown Sacramento. Signs denote the park's location from I-5. The park forms one end of the 32-mile Jedediah Smith Bike Trail, so bicycle riders will find a place to rest in the shade by the river. Amateur naturalists and horseback riders will find trails to enjoy, while picnickers can barbeque a group meal in the reservable picnic areas. Adults and big kids can play softball or horseshoes, while playground equipment will be just fine for smaller kids.
