A day in Gibraltar is often a great thing to do with kids as there’s lots to see and do but whatever you do make sure take your passports! You can get across by foot or by car to the top of mountain and explore the caves and medieval castle, admire the magnificent views and spot the monkeys. Off shore you can enjoy boat trips to see dolphins and whales, possibly even the blue whale if you are really lucky. There are many birds on the rock in spring and autumn, great for bird-watchers. It is about an hour’s drive to Gibraltar from Marbella or you can get a bus from Marbella bus station to La Linea which is the town just outside Gibraltar – the bus drops you 5 minutes’ walk from the border. Also remember the currency is in pounds not euros!
