Guss Mobile Sauna

Guss is a wood-fired mobile sauna that sets up beside the Willamette River in Southeast Portland, most days at Sellwood Riverfront Park by the dock or across the water at Willamette Park by the boat ramp, so bathers can alternate wood-fired heat with a river plunge. Drop-in 60-minute sessions cost $30 for ages 16 and over, five-session punch passes are $120, and private rentals for up to 12 people run $280 per hour. Session dates and the exact spot are confirmed at booking.
