The cone at the head of the UNESCO-listed lava tube system. Walks leave every 30 minutes with a guide, and daily numbers are capped. Inside the crater the forest is damp and cool, a different air from the coast. From the rim, other oreum roll away in waves. You cannot walk in without a booking, so reserve first.
