But guests at the five-star Heritance Kandalama​, designed by architect Geoffrey Bawa, should be wary of unwelcome intruders as a sticker on the sliding balcony door makes clear in four languages.

Beneath a picture of three monkeys, the sticker warns: "Please Do not Feed Us! We can be a real nuisance."

Guests are also asked to keep the door to the balcony, which is covered in vines that appear to merge with the surrounding jungle, closed and locked.

In a secluded area surrounded by world heritage sites including the stunning rock fortress of Sigiriya, such precautions seem excessive. After all, the whiskery grey langurs are far from threatening as they play fight along the open-air corridors and splash in the swimming pool at sunrise.

However, it is a different story with the hotel's other resident monkeys, the long-nippled macaques with their sharp teeth and Friar Tuck haircuts.

Several species of macaques are apparently used in animal testing so they have good reason to declare war on humans. However, the cranky alpha male who bares his teeth and charges me while I'm nursing a gin-and-tonic could have just asked if I'd pour him a glass of Mother's Ruin.

Admittedly, I have a bad track record with primates – a monkey once tried to steal a banana from my pocket during a wedding in India (no, that's not a euphemism). An orangutan in a safari park in Indonesia once had to delicately remove my hand that had accidentally slipped onto her backside.

Back on the balcony, glass and I both go flying, but there is no escape thanks to my thoughtful friend Trish who closes the balcony door and laughs herself a hernia from inside the safety of the room.

Eventually, she stops cackling long enough to let me inside as my monkey nemesis bares his teeth, charges again and thumps on the sliding door until he notices my half-empty glass of gin.

It's a glass half-full for the cranky macaque and his gang of droopy-nippled alcoholics who slurp up the spilt gin.

Macaques turn out to be two-pot screamers; it certainly does not take long for this barrel of monkeys to start squawking like teenage girls, scurrying back and forth, staring at their reflections in the window.

The next morning we're awoken with a scream after Trish ventures on to her balcony for a coffee, only to be met by Papa Monkey.

Disappointed by the lack of alcohol in her mug, he breaks it and then disgraces himself by urinating on her balcony table and chairs. That's the type of monkey business that's unlikely to win a second date, she tells the bemused hotel staff later.

Monkey 2, Humans 0.

Not all of Sri Lanka's wildlife are as ill-mannered as the macaques of Kandalama. That afternoon, we take a bum-numbing ride along pot-holed, muddy roads in nearby Minneriya​ Wildlife Sanctuary in search of its elephant population.

Angry storm clouds gather overhead, and heavy raindrops cool the stifling air, as we drive deeper into the park, which is also home to the friendly langur and menacing macaque, crocodiles, monitors and pythons as well as a number of threatened bird species.

Eventually, we find a small herd of elephants, including heavily pregnant mothers, shy babies and inquisitive juveniles, munching contentedly on grass and occasionally looking up to pose for our cameras.

That evening, we discover a new front has opened in the monkey's war on humans after one of our travelling companions tells of how she was sheltering from the burning sun under a tree when she felt a raindrop land on her head.

Looking up to a cloudless sky, she sees the "raindrops" falling around her are courtesy of a monkey perched on a branch.
