Getting there & away
The small Central de Autobuses is on Canal (Calzada de la Estación), 3km west of the center. Tickets can be purchased at the station. Primera Plus (and Flecha Amarilla) tickets can be bought at Transportadora Turística Imperial (154 5408; www.transtur-imperial.com; Plaza Principal 18, 1st fl; 9am-8pm). Tickets for ETN and Primera Plus can be purchased from larger hotels.
If you need a car for more than a few days, it may be worth organizing one through rental agencies in Querétaro. The only San Miguel-based agency is Hola Rent-a-Car (152-01-98; www.holarentacar.com; Hotel San Francisco; 9am-2pm & 4-7pm), inside Posada San Francisco. Prices start around M$620 per day including insurance. Reserve at least a week ahead, especially during the high season.
The nearest tarmac is the Aeropuerto Internacional del Bajío, between León and Silao, around 1½ hours away by car.
