There will be a taxi service waiting for those who need to get to Ensenada. Please walk across the border and there will be a taxi service with a "Boda Nuno" sign. Please refer here for updates on taxis.
If you would like to have a car instead of taking a taxi you can rent a car at any rental place in San Diego. You can take rental cars across the border you would just need to notify the car rental company that you are doing so. Please keep in mind driving back to San Diego from Ensenada/Tijuana on Sundays are difficult. Traffic is the worst all day Sunday getting back into San Diego, so it is advised to head back very early Sunday morning or leave Monday, anytime. Keep in mind we are having a Tornaboda, Sunday 8/28/22!! :)
