A TikTok user has issued a stark warning to the public about visiting Benidorm beach at night.

The viral post, which has amassed over 150,000 likes and thousands of shares, reveals why the dunes of the popular tourist spot should be avoided after dark. User @frankthestagman cautioned that you could face hefty fines for evening beach walks.

Despite admitting he had never witnessed anyone being fined for nighttime beach activities, the TikTok creator highlighted another crucial reason to steer clear of the sandy shores.

Frank, also known as Frank the Stag Man, revealed: “You’d be amazed at what happens down towards the front there. Lots of people come down here at night and get up to stuff that’s kind of like, how can I put it, naughty.”

“If you come down to the beach at night and you find a little corner down there or between the deck chairs or put them together so you can do what you wanna do, please bear in mind there are people who are called the Serpientes [the serpents]. What they do is they crawl down underneath these deck chairs and they can relieve you of your handbags, your phone, your wallets.”

The TikTok creator also warned those who were skinny dipping in the ocean were also at risk of being accosted by the group.

“There’s a very big chance that you will lose your belongings,” he said. “The people who do that sort of stuff target people that are going down onto the beaches at night for fun”.

Holidaymakers bound for or returning from the popular resort expressed their dismay upon hearing such warnings. One concerned traveller posted online: “I’m only hearing negative things and going in a month getting worried never been to Benidorm before.”

Another shared a personal incident: “My sister got robbed on this beach, yes at night… Not saying what she was up to.”

Meanwhile, a third expected something less sinister: “I was expecting you to say the Benidorm sea monster comes out lol.”

Visitors should note that breaking local rules could result in hefty penalties. Engaging in sexual activities on the beach might land you a £641 fine, while failing to cover up swimwear appropriately can lead to a £256 charge.

Additionally, an odd regulation penalises nocturnal swimmersif caught in the sea from midnight to 7am, fines range from £640 to £1,026.
