Jack Johnson and Ben Howard will headline a new North Devon festival this July, with more big acts expected to be announced over the coming weeks. Somersault Festival will be a five-day summer camp on the Castle Hill estate, billed as five day's of music, adventure and outdoor living in the heart of the South West.

From the co-creators of the award-winning and highly acclaimed Wilderness festival, Somersault will offer a different alternative to this year’s more traditional festivals. From photography tutorials to theatre schools, there’s a raft of innovative workshops and adventures coupled up to a weekend of world-class headliners with the legendary Jack Johnson headlining Saturday night (his only UK appearance in 2014) and Devon’s very own Ben Howard closing on the Sunday night.

“We wanted to offer a completely new kind of summer festival experience – a five day summer camp that allows people to break out into the surrounding landscape and no longer be hemmed in to one event site,” announced festival organisers Tim Harvey and John Empson.

“It’s been a painstaking planning process but we are delighted to announce two world-class headliners in our inaugural year both of whom supported the concept right from the start.”

Back on dry land, activities promised include horse riding, trekking, moor running and mountain biking plus falconry, archery, yoga and circus skills.

“There’s an amazing line-up of support artists still to announce and we can’t wait to see the theatre, food and arts programme unfold over the next few months,” they continued. “For anyone wanting to combine a long weekend to the South West and a different kind of festival experience Somersault is the answer. We hope this will prove a landmark new show for the region that adds something special to the amazing range of activities already taking place across Cornwall and Devon each summer.”

Somersault Festival’s nominated charity is Surfers Against Sewage and both Jack Johnson and Ben Howard are known for their support of environmental education.

Jack Johnson said: “I love the UK. I love surfing. So playing a show in the South West is the perfect situation. Somersault sounds like the perfect festival.”

The Festival will run from Thursday, July 17 to Monday, July 21, Super early bird day tickets will be from £39.50 while long weekend tickets from £99.50 from Ticketmaster.
