You can also take a ferry from Tangier.
From Spain: Walk across the border from La Linea de la Concepcion.
Hack: Remember to get your passport stamped by Spain as you walk across. They forgot to stamp our passport and waved us out. As Indian passport holders we are extra cautious and walked back to check again.
WHAT TO DO:
Gibraltar is super expensive. Most people prefer a day trip from Tangier or Spain. But an ideal stay would be 2 to 3 days. We spent 3 days in Gibraltar and fell in love with this quirky, yet quaint place. This country is longish and has one ‘market’ street that stretches along the length. It seems like the 30,000 Gibraltarians know each other. Walk into a bar and they are all on a first name basis with the customers. We managed to walk across the length and breadth of this territory, but plenty of bus options for those who want a ride.
Cost: 18.5 GBP for a one way cable car ride up the rock and entry to few sites. The round trip cable car ride costs around 2.5 GBP more which is not recommended.
Set aside an entire day for the rock. There are two options to climb up – cable car or by foot. Unless you are extremely fit, take the cable car. It’s a long uphill climb and coming down needs a lot of energy. Begin at the top where the cable car stops. There is a taxi tour of the rock which takes about 1.5 hr, unless you absolutely cannot walk this tour isn’t the right way to see the rock. Summit of the rock is super picturesque and you get to take memories.
