Quick Summary of Travel Cost and Travel Time

🚗 Driving From San Diego to Mexicali

Driving is the most direct way to reach Mexicali. Depart San Diego on Interstate 8 East, passing through the Cuyamaca Mountains and Imperial Valley for approximately 110 miles. Near El Centro, head south on State Route 111 directly into Calexico. Drivers have two border checkpoint choices: the downtown Calexico West Port of Entry (leading straight into historic downtown Mexicali) or Calexico East (primarily used for commercial freight and passenger vehicles seeking less congested crossings).

If you drive your vehicle across, you must purchase a certified Mexican auto liability insurance policy online before departure, as United States policies are invalid in Baja California. Mexicali sits inside the border Free Zone, so no Temporary Vehicle Importation Permit (TIP) is required for local travel.

🚌 Bus Options

Intercity bus carriers such as Greyhound and FlixBus operate direct routes from downtown San Diego to the Calexico bus terminal. Journey times average 2 hours and 45 minutes, with standard one-way fares ranging between $22 and $40 when booked ahead. The Calexico bus depot sits within easy walking distance (under two blocks) of the downtown international pedestrian turnstiles.

Once you disembark, you can simply stroll with your luggage to the border facility, clear Mexican immigration (INM), and exit directly onto the streets of Mexicali, where local taxis are readily available.

🚆 Train + Bus Combo

While there is no direct passenger rail line running from San Diego to Mexicali, transit riders often use a dual-country combination.

Take the San Diego MTS Trolley (UC San Diego Blue Line) south from downtown to San Ysidro for $2.50 to $3.00, walk across into Tijuana, and catch an authorized Mexican coach bus (such as Autobuses ABC or Omnibus de México) directly from the Tijuana border terminal or central bus station to Mexicali. This coach leg travels east along Mexico Federal Highway 2D through the scenic La Rumorosa mountain pass, arriving in Mexicali in about 2.5 to 3 hours for roughly $20 to $35.

🚖 Rideshare / Taxi

Hailing an Uber, Lyft, or traditional taxi from San Diego straight to the Calexico border provides point-to-point convenience without requiring you to navigate mountain highways. Because US rideshare drivers cannot take passengers across the international boundary, set your destination to the Calexico downtown port of entry (along East 1st Street).

The drive takes roughly 2 hours under standard traffic conditions, with standard fares pricing out between $130 and $190. From the drop-off curb, you simply walk through the pedestrian portal into Mexico and hail a local Mexicali taxi on the other side.

🚶 Walking Across the Border

Walking across the border at the Calexico West Port of Entry is simple, highly economical, and avoids the vehicular return lines that can back up for hours. Numerous secure, long-term parking garages and surface lots operate on the Calexico side for $10 to $20 per day. From these lots, follow the pedestrian pathways into the Mexican immigration building.

Foreign travelers must present a valid passport, complete an FMM (Forma Migratoria Múltiple) entry form, and submit bags to X-ray scanning. As soon as you pass through the inspection exit, you are in downtown Mexicali, surrounded by municipal bus stops, city parks, and metered taxis.
