This day , we decided to see active volcano and hot water springs. This was a bit of disappoiment for us. We booked a group tour. We took a cable car to get to ferry point. There was some time for ferry to start. So we decided to take souvenirs of Santorini. Then ferry started and we were in middle of nowhere after some time. After about half hour, we saw rocks which were jet black in color. Our guide asked us to get down there. It was very windy the day we went and we had to apply force to walk. And added to it, we were walking on a mountain upward. We walked and walked hoping to see an active volcano but in vein. There were some black ash like things and there was smoke long ago it seems. Everything seemed normal to us. Views of ocean were great though. While decending, air pushed us so hard that we even fell down at some places. Then they took us to hot springs. Boat was stopped at 30 feet in water and we were asked to dive and swim till hot springs. We didnot know how to swim so we decided to see people doing. Many told water was very hot and going was worth it.
Then we tried roaming around Santorini. If anyone is interested in biking, take Indian licence. They asked for Indian licence for bikes and we didnot take it. So had to roam around in cabs and shared cabs.
