One good thing about a town that’s as flat as a tortilla: It’s perfect for exploring on a bike. One of the best places to ride is along the paved 32-mile American River Parkway that starts near Old Sacramento and heads upriver all the way to Folsom lake. If you didn’t bring your own wheels, the friendly crew at City Bicycle Works (2419 K St. at 24th Street; 916/447-2453; www.citybicycleworks.com), will rent you one for about $15 a day.
