Johnson’s Beach in Guerneville is the quintessential Russian River summer spot — a sandy beach on the river itself, with rentable canoes, kayaks, and inner tubes, plus a snack bar for when you need a break from the water. It’s about 45 minutes from Sebastopol, an easy day trip when temperatures climb and the coast feels like too far a drive. The water is calm and slow-moving through this stretch of the river, making it a good option for kids and casual swimmers alike. Summer weekends draw a lively, festive crowd, so go on a weekday if you’re after something quieter. It’s a seasonal operation, so it’s worth confirming it’s open before making the trip outside of summer months.
