I've been to San Diego a few times and this time I'm thinking of a daytrip to Tijuana.
Is it worth to go there?
I know that I'm not allowed to cross the border with my rental car.
I heard that I can take a tram to the border an walk the to Tijuana?
What can I see there?
Is ist really a shopping paradise, like my travellguide is telling?
IS IT SAFE?
I'm thankful for any recomandation or any tips.
