Sip a passion fruit punch at this small beach hut beside Saint Mark Parish—Soufrière’s splendid Roman Catholic church, built in 1880—then hop in the homespun sulfur soaking pools on the shoreline. Here, a fumarole warms the sea water and injects bubbles into this natural volcanic spa. For an even more indulgent experience, rent a sun lounger, book a session with the massage therapist, or visit for a Sunday barbecue, when live music creates a festive vibe.
