I think monkeys of Gibraltar are actually the biggest attraction of Gibraltar. Of course tourists come here to see the rock of Gibraltar, Gibraltor strait and take a peak at Africa (Morocco to be precise). However I think monkeys make this place popular, memorable and different. Not in too many other places you can see huge monkeys so close - close enough for a selfie. I really enjoyed walking up the trails but I was constantly looking around since one monkey jumped right in front of me and scared me. There are everywhere - in the trees , on the fences, on the walking paths constantly looking at you.
