Kayaking into the Lava Tunnels of Vulcano, Three Grades

The sea caves on Vulcano are lava, and the way into them is by kayak or by swimming through. The trips come in three grades, easy, medium and difficult, so the choice gets made before you book rather than out on the water. Someone who has never held a paddle can do the easy one. The harder ones are built for kayakers who want the caves, the tunnels and the rougher stretches of coast. Along the way the water goes warm without warning. Thermal springs come up in the bays and grottoes around the island, and you can swim in them where they surface. The booking is private, so the grade and the pace are set by whoever is in the boat.
