Tadeo was the best tour guide! Due to COVID restrictions we were unable to meet at the original starting point (McDonald's), so we had to cross ourselves. The process was super easy and Tadeo was waiting right on the other side where we could not miss him. On the way back, he walked with us right to the border where we lined up to re-enter the US. No confusion or issues with safety at all.
The experience was very personable and provided a great taste of Tijuana for those looking for a good day trip. Expect the trip to run about 4-5 hours with a fair amount of walking. The border is a busy place which may seem stressful at first, but we did not feel unsafe at any point.
