While it's true that October heralds the return of winter, it is still a beautiful month to visit Gibraltar and most of the activities that you can do in the summer can still be done.
There are many sights to see and many places to explore in Gibraltar. Among the most popular sights to see is the Barbary Macaques, a species of tailless primates that roam and live freely throughout Gibraltar. They are the only monkeys in Europe that are 'free-living', meaning that they don't live in a zoo.
There are approximately 160 of these monkeys living in Gibraltar in two main areas: Queens Gate, also known as Ape's Den, and at the Great Siege area. They can and do interact with visitors but you should always use caution as they are still wild animals.
