Official Quito Travel Site Quito was named a UNESCO World Heritage Site in 1978 and has appropriately well-documented tourism and visitor sites on the internet and in the city. Perhaps the best place to start, Official Quito Site offers tourism information in both English and Spanish, as well as thorough introductions to the entire city: lodging, eating out, getting to/from Quito, top attractions, shopping, nightlife, history and culture. It also has an searchable, interactive map of all the main sights in the city.

Tourist information centers (which sponsor this site) are located all over the city: the Mariscal Sucre Airport international arrivals, Historic Center (on the main square, Plaza Grande, on the ground floor of the Palacio Municipal), in the Mariscal quarter on Parque Gabriela Mistral (Reina Victoria y Luís Cordero), the Museo Nacional del Banco Central (Avenida Patria y 6 de Diciembre). Visit any for maps, brochures, and helpful guides to direct you around the region and off the beaten track. The visitor centre in the Historic Centre also has lockers for leaving bags, a beautiful shop, bookshop. This office offers free guided tours of the Old Town and beyond, where visitors only pay the entrances to sights, etc. 

The Official Quito Site suggests several links for visitors, one being the region's website.  The Official site also suggests several hotel booking services and ViveEcuador , the official Ministry of Tourism website about Ecuador and its various regions.

Also, the website Ecuadorial has a ton of links for tourism outside and around the Quito region, as well as through all of Ecuador.
