Exciting new activities have been confirmed for St Albans’ Meraki Festival 2018.

Intrepid explorers can squeeze through a multi-layer 90ft caving system which includes stalagmites, sumps, and is not for the claustrophobic.

It is the UKs first above-ground mobile caving experience and allows curious adventurers to try the dangerous sport in a safe and controlled environment.

Building on last year’s swimming pools and hot tub attractions, a giant water slide measuring 50ft tall and 120ft long will be the centrepiece of the Meraki splash park.

There will also be a roller disco with smoke machines, flashing lights and skates to complete the 80s themed entertainment.

On top of these, highlights of the inaugural festival will return for a second year running - laser tag and the silent disco. Meraki Festival 2018 will run from August 10 to 12. More activity announcements are to come.
