As Gibraltar is built on and around a big rock, things tend to rise up pretty rapidly. Therefore although it may only appear to be a short distance between places (as the crow flies), it can actually be quite a long way when you go by road due to the zig-zag approach to road building here.
It is therefore to have another mode of transport other than just feet to get around. Do note however that parking is not especially easy.
Also if you cross the border, you can be liable to fairly sever delays either from Spanish customs (who sometimes like to give a bit of grief to people who are leaving Gibraltar due to the politics). Also, the runway crosses the road that comes in to Gibraltar, and guess who gets priority in thse situations! If you time your border crossing, you will find yourself in a queue of cars as you watch an airplane land right in front of you. (It's actually quite interesting the first time you see it!).
Best way into Gibraltar is by foot as the queues in and out by car can be a bit long. You can park in La Linea de la Concepcion in Spain and just walk 5 minutes across to Gibraltar. Then take the bus (every 15 mins)for 1 euro or 60p to the main parts of Gibraltar.
Spain and UK do not really agree about the Gibraltar status. Border crossing can be really time consuming (more than 2 hours for me) when exiting Gibraltar, as spanish border police control every car. Be prepared to a long wait, that is really stressful in the summer heat.
Do not take your car across the border!!! The line of cars to get in is very long. It might take hours.
As you approach the border, keep in the left lane. Turn to the left as you pass the control point and you will find parking on the Spanish side. Walk through the checkpoint and take a bus down town.
The easiest way to enter Gibraltar is by car from Spain. Entry is straightforward, just drive across the border into the town, but leaving can be a little more difficult. Because of Gibraltars tax free status, the Spanish customs are likely to search vehicles to check for goods bought there. This can lead to long delays, an hour is not unusual. Try to avoid rush hours times. Also periodically, depending on the political climate, even longer delays can occur.
Maby it's a good idea to leave your car to the spanish side (La Linea). This way you will find an parking place and go fast trough the border. Crossing the border by foot is usually much faster than by car or bus.
Flights from the UK direct. If arriving by car the lines at the border crossing look horrendous - leave your car in La Linea, theres a good underground carpark nearby and then walk into Gib. Beware of passing aeroplanes though, you walk across the middle of the runway, could this be a security hazard?
