I will be in San Diego for a few days in March and considering crossing into Tijuana on foot for a few hours during the daytime. I am an experienced solo female traveller and will be traveling mostly by foot just to poke around the area a bit. Should I be very concerned about safety? Just to be clear, I have done my share of slumming in various corners of the world, but not sure if Tijuana is particularly dangerous or off limits right now even in the tourist area.
I have a global entry card which can be used for SENTRI lanes. What kind of crossing and return time should I expect if I were to do the trip on a Thursday or Friday? Thank you for any advice.
