Recently took my wife on a tour of the old jail, which has been fantastically transformed. Guide was very informative and tours go every half hour. Check online availability before travelling, we did and were able to pay at the gate. I feel the site is still in the early stages of development and the longer the site is open it will progress into one of northern Ireland's top attractions. Hopefully they can renovate some of the unsafe structural areas so the public can see other areas of the prison in future visits.
