## Overview

Sauna Moon parks a mobile wood-fired cedar barrel on Alki Beach Park in West Seattle. Heat is communal (about 12 to 14 seats). Cold is open-water plunges in Puget Sound, not a filtered tub. The operator runs Thursday, Friday, and Saturday sessions; your booking confirmation names which of two Alki permit pins to use.
