On a recommendation fo a german girl at the hostel we ventured about 15-20k north of Quito to the Equator to a place aptly named Mitad del Mundo (Middle of the World). It took 3 buses and about 1 1/2 hours to get there and was probably not worth the effort!
It is the sight of some controversy as some claim the equator is not exactly where the French scientists that came here many years ago claim it is!
We took a few pics in both hemispheres and did a trip to an active volcanic crater nearby called Pululahua. People actually live in this crater! You have to go in the morning because by the afternoon the place is covered in cloud! It was fairly scenic.
