A good place to start is the Quito Visitors' Bureau. It has several information centres around the city. These include at the International and Domestic Arrivals terminals at the airport; the Parque Gabriela Mistral in the Mariscal District (just north of Plaza Foch); the Banco Central Museum in the Masiscal District; and finally, in the Old Town, on the ground floor of the Palacio Municipal on one side of Plaza Grande - their main centre.
The main centre includes helpful English-speaking staff, lockers for leaving bags, maps, leaflets and books for sale, a store of Ecuadorian crafts. This centre also offers free guided tours of the Old Town, where visitors only pay the admission fees to sights. The contacts for the main office are: (+593 2) 2570 - 786 / 2586 - 591, email@example.com
The main iTur (national tourist information offices, ) is located in northern Quito, close to La Carolina park and El Jardin malls, to one side of the Ministry of Tourism, Av. Eloy Alfaro y Carlos Tobar.
