Nearly every year, thousands of music lovers around the world flock to the iconic Glastonbury Festival. It’s a chance to see some of the best up-and-coming acts, and to be part of one of the world’s most famous festivals.

But for those who don’t have tickets (or can’t afford them), there is one last resort—trying to break in. Here’s what you need to know if you’re thinking about taking a shot at breaking into Glastonbury.

It’s bloody hard. Near impossible

It didn’t use to be though. In fact prior to 2000 it was common place for break-ins and not just a few. Poor fences, bent security and the sheer number of people milling around the site made it difficult to police.

Michael Eavis, the festival’s founder, even encouraged it in the past by forklifting a fence allowing two thousand revellers into the festival for free.

In the late 90s it was believed that as many people sneaked in as bought tickets. Swelling numbers from 80,000 to nearer 160,000. But 2000 was a turning point, Eavis was fined for breaching licensing conditions and the mood had (finally) turned sour on the fence jumpers.

The festival took a year off in 2001 due to safety fears, but bounced back with the now lauded ‘super fence’. The super fence is a large, multi-layered security barrier that surrounds the festival site at Worthy Farm.

The security measures are tough

The super fence is made up of several layers of fencing, including chain link and metal barriers, as well as security personnel and cameras to monitor activity. It is also regularly patrolled by security personnel, dogs and CCTV cameras. It has been a huge success in keeping those out without tickets.

Firstly, it’s important to understand that the security measures at Glastonbury are incredibly tough. There are CCTV cameras everywhere, and security guards patrol both inside and outside of the festival grounds.

If you do manage to make it onto the site, chances are you won’t stay for long – and if you do get caught, you’ll likely find yourself in a sticky situation with local law enforcement. So before you even think about trying to sneak in, consider how much trouble could come from getting caught!

But is it possible?

Of course it is, but you need some balls. Queue Zac Alsop. Zac has hitched on private jets, snuck into the ring at an Anthony Joshua fight and even managed to blag his way onto the Team GB Olympic parade float.

Piecing together clips from previous break-ins at the festival Zac located one of the many waterways that flow through the site. The muddy ditches provided a weak point that were difficult to fence and harder to police.

Zac waded through the grime to prove that even the world’s hardest festival to break into is penetrable, check out his adventures below.
