The park is located exactly where the American River flows into the larger Sacramento River.
It marks the western terminus of the Jedediah Smith Memorial Trail, one of the longest paved bike trails in the region.
The park grounds are situated in a designated floodplain, necessitating periodic closures during high-water seasons.
The boat ramp area is a popular departure point for anglers targeting Chinook salmon and steelhead trout.
The park's topography is largely composed of river-deposited sediment, creating a flat, low-lying basin environment.
Discovery Park is a 302-acre regional park situated at the confluence of the American and Sacramento Rivers. It serves as the primary trailhead for the 32-mile Jedediah Smith Memorial Trail, which connects Sacramento to Folsom. The park provides boat launch facilities with access to both major river systems. Recreational infrastructure includes designated picnic areas, multi-use turf fields, and extensive open space for cycling and walking. The landscape consists of riparian woodland and floodplains, periodically affected by seasonal water level fluctuations. It frequently hosts large-scale outdoor festivals and community events due to its expansive staging areas. Fishing is a common activity along the riverbanks, particularly near the confluence point. The site is managed by the Sacramento County Department of Regional Parks.
