The entrance price was a little on the expensive side at £11 per Adult. You can upgrade this to include a 45 minute extended guided tour of the Castle Apartments. I bought the cheaper ticket.
Included in the price is an Audio Guide which I found very useful in terms of history and insight into the Castle. Thankfully the weather was nice so I enjoyed my leisurely stroll around the Castle Wall & Keep. As usual I took photographs for you to enjoy.
