Andres and Tadeo were both lovely tour guides. Please note that you do have to pay for parking close to the border. Once you park, walk over to the Mexican side of the border and meet your tour guide there. A very detailed email with meeting details is sent over Border Tours the day before or morning of your trip. My brother and I felt safe the whole time on this group tour of about 12 people. We got to see a local candy shop, walked through some local markets, and learned about Tijuana's history. We also got some nice picture stops, lunch (and a margarita) was paid for, and ended the tour with a tequila tasting. Andres and Tadeo were super friendly and made sure the group stayed together throughout the tour. I would definitely recommend this tour if this is your first time in Tijuana!
