The totally free event allowed daring youngsters to try the high ropes, wall climbing as well as more sedate activities such as dissecting owl pellets.

It was held as part of the Ouse Fest fortnight which has seen more than 60 events held over two weeks across the area from Ely, to Denver, March and Manea and many more in between.

Other activities included archery lessons, mosaic coaster making and trails for people to follow.

The Raptor Foundation was also present together with the Barn Owl Conservation group, which a key partner of the Ouse Washes Partnership which aims to open up the countryside to local people.

Around 350 turned up for the event, which organisers are promises will be even bigger and better next year.

Mark Nokkert, programme manager for the Ouse Washes Partnership, said: “It was an absolutely fantastic day. We are trying to promote the landscape and encourage people to appreciate what they have right here on their doorstep. Everyone seemed to enjoy the event and we hope even more will come along next year when the fortnight will run from July 18 to 31.”
