I'm looking to spend a week in Ecuador - splitting my time between Quito and 'volcano alley.' I'd like to hike (day hikes only) perhaps around Volcan Cotopaxi, Volcan Corazon, Quilotoa lagoon, etc but minimize my driving time. Ideally, I'd love a place with several trails (between 3 and 6 hours each) right from my doorstep, no driving required. (I know that's asking a lot.) Any suggestions? Many thanks!!
