This is the only time I've visited an active volcano. You can't get too close or the fumes could kill you. There's a very pungent smell. This was one of the hottest days of my life, but luckily it was dry heat. My husband and I had hats and big bottles of water with us and were shocked that many of the tourists came without hats and with nothing to drink. One British man - who was as red as a lobster - looked like he was going to have a heart attack. This was taken on our honeymoon in 2008 on the Greek Island of Santorini.
