The day we reached Santorini, we determined that we have to take the Caldera cruise to visit the famous Nea Kameni volcano from close! Our cruise took us from Fira straight to the volcano. My boyfriend and I are avid outdoor enthusiasts and hence, we were determined enough to hike to the volcano. If you haven't enjoyed outdoor activity, I have to warn you because the hike is strenuous. There are no steeps, but the hot sun will surely consume a lot of your energy. It is better to limit your luggage and we carried only water with us. Once we reached volcano top, we realized that we made a worthwhile trip. The view of island from the top was incredible. You can get a nice 360 degree view of the low lying islands, something no one wants to miss. We took a lot of snaps of the island. We didn't take hot springs tour mainly because we didn't want to get wet. However, we saw many people enjoying the springs despite the horrible smell.
