Getting there & away
Mexican tourist cards are available 24 hours a day at the San Ysidro–Tijuana border in the Mexican immigration office (682-64-39). They are also available – although less dependably –at a small office in the main bus terminal (Central Camionera, below). You are required to have one as you cross the border, but this is rarely enforced north of Ensenada.
The San Ysidro border crossing, which is a 10-minute walk from downtown Tijuana, is open 24 hours, but motorists may find the Mesa de Otay crossing (also open 24 hours) less congested; it’s 8km to the east of San Ysidro.
Rental agencies in San Diego are the cheapest option, but most of them only allow journeys as far as Ensenada. California Baja Rent-A-Car (619-470-7368; www.cabaja.com), in Spring Valley, California, 32km from downtown San Diego and 24km from San Ysidro, is a pricey option but allows you to continue driving beyond Ensenada.
The Aeropuerto Internacional Abelardo L Rodríguez (683-24-18) is in Mesa de Otay, east of downtown.
