What started three years ago as a 21st birthday party for 300 friends has grown into a full-blown festival for 5,000 people - and it’s still run by the same group of friends who care about music, connection and community.

Four days and nights of House, UKG, Jungle, Drum & Bass + more, all set against the stunning backdrop of Charlton Park Estate - rolling fields, lime trees and the historic mansion built in 1607, giving the weekend a unique blend of music, history and atmosphere.

GemFest is fully independent and built with attention to every detail by a small team who actually live and breathe the festival. The festival returns on 11th - 14th June 2026 at Charlton Park Estate, Malmesbury, SN16 9LL. See you in the fields.
