Before crossing the Straight of Gibraltar from southern Spain into Morocco, Ben and I decided that we would go and explore the actual Rock of Gibraltar.
The entire country (technically UK territory) could be explored in a number of hours. We walked about 2/3rd the way across the entire country in a matter of 20 - 30 minutes.
There is a gondola station at the base of the rock and it was entirely empty. We paid for a ride to the top and had the entire gondola to ourselves (and the gondola operator).
The top of the rock offers some of the most spectacular views you could imagine. There was a huge cloud that moved in from the north side and it was surreal actually walking through the cloud. To the south you can see the sun glistening far out into the Mediterranean Sea.
Another surprise was that the top is full of apes. There are signs posted everywhere informing you that you'll be fined $2,000 for feeding them. It was pretty hard walking around up there without them crossing your path.
We assumed that they were all peaceful apes, but it definitely makes one feel a little uneasy walking by an entire family of them.
