Sacramento has an average of 270 sunny days per year, and local residents love to take advantage of the nice weather on the city's extensive bike trails.
One trail runs along the Sacramento River, starting in Old Sacramento and continuing down the river (with a couple of places where cyclists have to get off and then back on the levee path). Much of this bike trail is quiet and offers nice river views.
The other, more popular, trail is the Jedediah Smith Memorial Trail. It follows the American River for 32 miles, from the confluence of the American and Sacramento Rivers just north of downtown to Folsom Lake. Due to the varied nature and scenic points, this trail is also a great place for hiking and seeing wildlife.
Bikes can be rented in Old Sacramento and various spots along the American River bikeway.
