Azerbaijan offers some of the most unusual wellness experiences in the world — from Naftalan's famous therapeutic crude oil baths (medically supervised, used since the 13th century) to mountain spring waters, traditional Azerbaijani hammam (bathhouse), and world-class spa facilities at the Four Seasons and Fairmont hotels in Baku. Our wellness experiences range from a single spa afternoon in Baku to a multi-day Naftalan oil bath retreat.
