This was the CRAZIEST day of our entire trip.
We left at 7.30am to drive down to Gibraltar (a three hour drive away, located at the very bottom of Spain), and we arrived at about 10.30am.
Following the advice from the Internet (always a risk) we parked in Spain and crossed the border into Gibraltar by foot. This was a super smart decision, because by the time we made it back from the rock to border control we were in a mad rush, and the car queue to get out was so long. The internet told me that Spanish border control authorities can stop and fully search your car if they just decide they want to, and that they regularly do this - and boy, the internet was not wrong! The car park was a five/ten minute walk from border control, but it saved us hours and avoided us a lot of stress about potentially missing our train to Madrid.
It took us almost two hours to get from border control to the top of the rock in Gibraltar, the buses were really slow and silly me didn't pre-book tickets for the cable car to get to the top.
The biggest reason we wanted to come here??
They were waiting for us the second we got off the cable car, and one even jumped from the window, off Dan's head and onto the girl in front of us. It opened her bag (using the zipper) and had pulled our a bag of nuts and jumped away again before any of us could really do anything about it!
