Tecate is on a spur of Mexican Federal Highway 2 that connects Tijuana with Mexicali via the central Sierra mountains. It is on the older, two-lane, east-west road which is toll-free.
A train from Campo, California, called the Tecate Ticket, travels to Tecate on a monthly basis (currently suspended due to a tunnel fire along the route). The train is run by the Pacific Southwest Railway Museum.
The city is the location of the Tecate Airport, which no longer operates due to low traffic. Instead, Tecate residents are served by nearby Tijuana International Airport (TIJ), with flights to most major Mexican cities and Shanghai and Tokyo. TIJ is closer to Tecate than Mexicali International Airport and thus used more frequently by Tecate residents
