Woodside Falconry Centre
I would like to recommend this as a great day out - we went today - I know, a Bank Holiday, and it was fine - no huge queues and apart from a small section of the A15 to Lincoln, no traffic.
Great for kids of all ages.
There was an outdoor flying display at 1200 (eagles, hawk, owl and falcon), Pig Racing at 1230, reptile talk at 1330, and an Indoor Owl display at 3pm.
You can feed and pet rabbits, guinea pigs and a small pony, there are woodland walks, a fishing pond, a tropical house with sandpit play area, tea rooms, and Bird of prey hatchery.
I thought we would be there for a couple of hours - we managed a full day.
