If you’ve ever found yourself standing on the southernmost tip of the Iberian Peninsula, staring out across the Strait of Gibraltar toward the misty outline of Morocco, you’ll know it’s a pretty surreal spot. British red telephone boxes sit beneath palm trees, fish and chip shops border tapas bars, and towering over it all is a massive, sheer limestone monolith: the Rock of Gibraltar.

It’s an incredible place for a day trip. But let’s be completely honest about what actually steals the show here. It isn’t the naval history or the duty-free shopping. It’s the furry, tail-free, chaotic locals who rule the high ground.

I’m talking, of course, about the infamous monkeys in Gibraltar.

Why are there monkeys in Gibraltar?

Technically speaking, these creatures aren’t monkeys at all—they are Barbary macaques, a species of wild tail-less apes originally native to the Atlas Mountains of Morocco and Algeria. They also happen to be the only wild monkey population on the entire European continent.

Legend has it that as long as the macaques remain on the Rock, Gibraltar will stay under British rule. Winston Churchill took this so seriously during World War II that when the population dwindled to just seven animals, he ordered an immediate top-up from North Africa.

Today, around 300 of them call the upper Rock home. And trust me, they know they’re protected. They walk around with the absolute swagger of landlord royals who haven’t paid rent since 1704.

The rules of seeing monkeys in Gibraltar

When you head up to the Upper Rock Nature Reserve—whether by foot, cable car, or a winding minibus tour—you’ll bump into the macaques almost immediately. They lounge on stone walls, sunbathe on the hoods of parked cars, and nonchalantly groom each other while tourists snap hundreds of photos.

They look adorable. They look photogenic. But make no mistake: the monkeys in Gibraltar are professional masterminds of petty theft.

If you want to keep your dignity (and your belongings) intact during your visit, keep these golden rules in mind:

• Zips are their love language. The sound of a backpack zipper opening is to a Barbary macaque what a dinner bell is to a Pavlovian dog. The second they hear that zip, they assume peanuts, chips, or a half-eaten sandwich are about to enter the chat. Keep your bags fully closed and strapped to your front.
• Plastic bags are public enemy number one. Carrying a plastic grocery bag or souvenir pouch up the Rock is basically an open invitation for a mugging. They can identify a plastic bag from fifty paces and will snatch it out of your hand with surgical precision.
• Never, ever feed them. Not only is it terrible for their health and illegal (carrying a hefty fine of up to £4,000), but food is what turns a chill primate into an aggressive acrobat.

Expect the unexpected

Even if you follow all the rules, these apes have no concept of personal space. You might be posing for a quiet view of the bay when suddenly, twenty pounds of furry curiosity drops onto your shoulders from an overhead cable.

The trick here is not to panic. Don’t scream, don’t make sudden movements, and definitely don’t try to touch them. (Pro-tip: eye contact can be interpreted as a challenge, and unless you’re prepared to wrestle a wild ape on a cliffside, just look at the scenery instead). Usually, if they realize you aren’t hiding a stash of snacks, they’ll hop off, bored, and move on to their next target.

Are they a little intimidating? Absolutely. Will you hold your breath every time one walks past your camera bag? Without a doubt.

But seeing the monkeys in Gibraltar in their element, against the backdrop of one of the most famous geographical landmarks in the world, is undeniably one of the most memorable experiences you can have in this corner of Europe. Just come in with your eyes open, your pockets empty of snacks, and your camera strap firmly wrapped around your wrist!
