Not ready for 6,000-foot climbs? Explore Quito’s volcanoes and valleys from dozens of lodges, boutique hotels, or hostels. Base yourself at historic La Casona de la Ronda (doubles from $140), and rent a front-suspension Trek 3500 from Biking Dutchman (from $15 per day). Jan, the owner, can put you on trails suited to your skill, whether you want to tour the old city or find your own singletrack. After the ride, catch a bus south to Baños, where you can splash under waterfalls and soak in hot springs in Ecuador’s famed gateway to the Amazon.
