Dogpatch Paddle runs a waterfront barrel sauna and cold plunge at Crane Cove Park on San Francisco's Dogpatch shoreline, alongside its kayak and paddleboard rentals. The barrel sauna is kept around 190°F and seats up to four, and the cold plunge sits near 49°F. One-hour public sessions start at $25 for sauna only or $35 with the plunge; a private booking reserves the whole sauna for a group of up to four. Public sessions run daily from 9 AM with the last at 4 PM, and members have longer hours.
