Those vents of steam you see along the water’s edge are evidence of Savusavu’s volcanic activity that simmers below the town’s surface. The main springs are just down from the aptly named Hot Springs Hotel. They are literally boiling: locals come to cook food in them. You’ll scald yourself if you touch them. The Savusavu Medical Centre next door has three therapeutic spa baths (40°C), and welcomes visitors. No appointment necessary.
