Near the top of the volcano, you could lay sticks across this entrance and the vapors were so hot they caused the sticks to catch fire! After a demonstration, everyone backed slowly away from the ledge. Some groups brought marshmallows and roasted them but our guide wasn't that prepared.
We could enter a cave at one point, which was like being in a dry sauna - the walls were hot to the touch and some rocks on the ground were too hot to touch. I could only stay in there for a few minutes before the heat drove me out.
|You can see the cave entry. And of course some stray dogs.|
