Best overall pick
Willoughby's Swimming Hole
Just Outside Downtown Downieville • Iconic Deep River Pool • Local Favorite For A Hot Day
A clear, emerald pool with smooth rocks and just enough room to spread a towel along the North Yuba.
A short drive or bike from town, Willoughby's feels like the classic Downieville swim scene: deep water, rock ledges, and current you can play in but still read. It’s popular on summer afternoons, yet never feels overbuilt—just a pullout, a trail, and the river doing its thing. Bring sturdy sandals for the scramble down and be ready for bracingly cold snowmelt even in midsummer.
02
Easiest in-town access
Downieville Confluence Beach
Downtown Riverfront • Lively In-Town Swimming Beach • Best Without Leaving Town
Where the Downie and North Yuba rivers meet, you get a pocket of small gravel bars, eddies, and quick dunk spots right in the heart of town.
If you want a swim without starting the car, head to the confluence area near the bridges and riverside paths. Small beaches and rock shelves give you options, from shallow kid-friendly splashing to deeper pockets where locals jump in after a ride. Expect company on hot weekends, along with the bonus of easy access to coffee, food, and restrooms just a short walk away.
03
Best for campers
Union Flat Campground River Bar
East Along Highway 49 • Shady Campground Gravel Bar • Perfect For Lingering Between Adventures
Below the pines at Union Flat Campground, a broad gravel bar steps right into a mellow stretch of the North Yuba.
Campers at Union Flat get a built-in beach, with easy access from the sites down to the river’s edge. The current tends to feel a little softer here than in some of the canyon sections, and the mix of sun patches and shade makes it comfortable for long afternoons. It’s a great choice if you want to set up chairs, let the day drift by, and wander back to camp when the air cools off.
04
Best roadside stop
Loganville Day-Use Beach
Highway 49 Toward Sierra City • Sunny Roadside River Cove • Ideal For Picnics And Quick Dips
Just off Highway 49, Loganville offers a small riverside cove with easy parking, picnic tables, and straightforward access to the water.
Loganville is the kind of place you pull into “just for a minute” and end up staying for hours. The river pinches into a bright, sunlit bend here, with enough flat shoreline for blankets and a cooler. It’s an easy add-on to a scenic drive, giving you a quick, refreshing plunge without a long hike or complicated directions.
05
Best for mountain views
Sierra City Bridge River Beach
Sierra City Village • Alpine Village Swimming Hole • Great For A Full-Day Outing
Tucked below the historic bridge in Sierra City, this river beach pairs cold, clear water with postcard views of the surrounding peaks.
A short drive upriver from Downieville, Sierra City’s bridge area feels like a high-country backdrop to your swim day. Small sand-and-gravel pockets line the banks, with deeper channels under the bridge where confident swimmers can really immerse in the snowmelt. Pair a few hours here with a stroll through the tiny main street or a stop for ice cream to make it a full outing.
