Interesting and worth a visit just don't expect anything on a large scale (my children were expecting to see dinosaurs as they had seen in the London Natural History Museum) plenty of facts and examples of local plants, farming techniques and wildlife. Be warned try to avoid the road leading from the coast very hair raising!!!!
The day we decided to visit it had been raining and we were told that everyone had gone home and the Castle would not open because it was too wet. The veiws from the top are spectacular and worth seeing even if you can't go into the Castle.
