Checking hours and using the appropriate lanes can streamline the process. If you plan to cross the Tijuana border on foot, ensure you use the designated pedestrian lanes.

6. Follow customs and security procedures: When going through the border crossing, be prepared for customs and security inspections. This may include presenting identification and travel documents, answering questions about your travel plans, and possibly having your bags or vehicle searched.
