Absolutely Amazing
During my 4 months in Ecuador I have visited in a number of locations in and around Quito. La Basilica is one of the absolute must-see sites in Quito.
The entrance fee is low, and certainly worth the price to enter La Basilica. Once inside this gothic cathedral, an elevator can be taken to go up to the upper floors, and from there an impressive view of the inside of the cathedral can be seen. The pews form an impressive site on their own, which is only augmented by the rows of stained glass windows at eye level.
In order to fully appreciate La Basilica one needs to have a certain level of physical fitness, and, preferably, a calmness when in high places. There are a few ladders to climb up, and numerous staircases. However, as someone who only mildly-tolerates heights, I found the "risk" to be well-worth the gain.
Be prepared for some amazing views of the city, and some picturesque photo opportunities from the tower of the cathedral.
Don't miss this opportunity. Even looking at La Basilica from the ground on the outside is amazing and interesting.
