In Oroville, relax at Riverbend Park. Check the flows first, but typically the Feather River moseys by the park, which itself is a clean, well-maintained place to play for families. Shallower spots near the park will allow you to wade in and cool off from a grassy shore; there are also several spots locals use for diving where the river is deeper. It’s a great spot for a swim if you’re also planning a picnic or a game of fetch with a furry friend.
If you’ve got a boat, the deep, cool waters of Lake Oroville—the city’s top recreational site — are tough to beat for local watersports. But it would be a mistake to discount it as a great swimming spot, too. Hundreds of coves, especially on the deeper north branch, make a day in the water just a short watercraft ride away — and many others still are within short hiking distance.
