Cotopaxi volcano is the second highest peak in Ecuador and btw, at the summit of this volcanic peak, you are closer to sun than from any other point on earth. Yep, closer than the peak of Mount Everest. How? This is because of the slight bulged (oblate ellipsoid) shape of earth along the equator. Hike up the peak for 40$, which includes transportation and guided trekking. You will have to leave really early in the morning to get there on time.
