About Monte Rio Recreation & Park District
Monte Rio Beach, operated by the Monte Rio Recreation & Park District, is the largest public beach on the lower Russian River in Sonoma County, California, located along Highway 116 near the Monte Rio Bridge. It is a seasonal, ADA-accessible river beach and swimming hole with boat rentals, a food concession, and recreational facilities, and the county officially monitors the water for safe swimming, which makes this a dependable stretch of river to swim in.
The beach sits on the lower Russian River surrounded by redwood-covered hills, described by the county tourism board as offering 'river and redwood views' from its picnic and barbecue areas near the Monte Rio Bridge.
Swimming at Monte Rio Recreation & Park District
The beach (locally called 'Big Rocky Beach') is a rocky/sandy river beach used for swimming and wading, with canoe, paddleboard, and kayak rentals available for those wanting to get further out on the water; the managing district explicitly advises against swimming in the stretch west of the Monte Rio Bridge, so swimming is concentrated in the beach area east/at the bridge. County health officials weekly test the water for bacterial contamination during the summer season, indicating it is treated as an active, official swimming site rather than an informal spot.
How to get to this swimming hole
The beach is at 20488 Highway 116 in Monte Rio, just east of the Monte Rio Bridge. An upper parking lot off Highway 116 is open year-round; a steep road/path leads down to the beach. A lower, seasonal parking lot (open mid-May through mid-September, closing at 8pm) sits closer to the sand via a wooden ADA-accessible pathway.
Parking: Two lots: an upper lot open year-round, and a lower lot open seasonally (mid-May to mid-September) that closes at 8pm; the lower lot has some compacted dirt/gravel spaces without standard striping.
The walk in
No real hike here. The water is a short walk from where you park. This is a drive-up beach, not a hike-in spot. From the lower seasonal parking lot it's a short walk (well under 5 minutes) down a steep access road/path to the sand; a wooden ADA-accessible pathway also connects the lot to the beach. From the year-round upper lot the walk down is longer and steeper but still well short of a hike (no formal trail or mileage is published).
Plan your visit
Bringing kids
OK with supervision
Sandy/rocky river beach with a gentle shoreline for wading, and the district explicitly markets the annual 'Big Rocky Games' as a children's event, suggesting family use is normal. However, no lifeguards are mentioned anywhere in official sources, the managing district itself warns swimming west of the Monte Rio Bridge is not recommended (implying current/depth risk there), and Sonoma County posts periodic 'check for algae' blue-green algae advisories at this beach. Supervise kids closely and stay on the main beach side of the bridge.
Parking
Lot
Two lots: an upper lot open year-round, and a lower lot open seasonally (mid-May to mid-September) that locks at 8:00 PM (visitors already on the beach after 8pm are told to move vehicles to the upper lot beforehand). Lower lot has some compacted dirt/gravel spaces without standard striping. No fee amount is published in official sources; access from the lower lot to the sand is a short but steep road/path.
Restrooms
Yes
Two accessible, all-gender restrooms located uphill from the beach near the parking area (type - vault vs. flush - not specified in official sources).
Water clarity
Varies with season and flow
No first-hand clarity description (murky/clear) was found in official or visitor sources. Sonoma County Environmental Health lists Monte Rio Beach among lower Russian River sites where seasonal blue-green algae 'check for algae' advisories are posted, and the lower Russian River in this reach is slow-moving and warm by late summer, which typically reduces clarity and can bring algae blooms in warm months. The county's weekly bacterial (E. coli/coliform) testing as of July 20, 2026 rated the beach 'low health risk,' which speaks to bacterial safety, not visual clarity.
Hours
Beach and boat-rental operations run seasonally from Memorial Day weekend through the last weekend in September; food concession and boat rentals operate Thursday-Sunday and Monday holidays, 10 AM-6 PM (no boat rentals issued after 4:30 PM); county water-quality (bacterial) monitoring runs Memorial Day through Labor Day.
On the water
Restrictions: No boat launch or motorized-boat/jet-ski access is mentioned in any official source; the district's own on-site rental fleet is entirely non-motorized (canoes, kayaks, paddleboards, a 2-hour-limit pedal boat, and tubes). The managing district advises against swimming (and by extension likely boating) west of the Monte Rio Bridge.
Life vests are provided free of charge with rentals.
