Sauna Bobor is a floating sauna club moored on the Danube at Dvořákovo nábrežie. It runs as a members' association: a season membership is €10 and each entry €12, or €15 for a single visit with day membership. The Finnish sauna takes 8 to 10 people, and you cool off in a tub of Danube water or down a ladder into the river. No reservations and no time limit. The season runs September to May: Tuesday and Thursday to Saturday 16:00–22:00, Sunday 14:00–22:00.
