We visited Pickering Castle on the way home from our holiday in North Yorkshire. Although it doesn't appear to be anything special, once inside it's really entertaining and worth the money. The kids really enjoyed looking around all the ruins, exploring the hidden rooms and climbing the steep steps. The shop is well worth a visit as you can buy viking hats etc - great for role playing! We wish we'd taken a picnic with us now as it would have been perfect. Really easy to find and a lovely way to end our holiday!
