1 hour and 15 minutes more or less
I'd say allow up to 2 hours theres a lot to see nice not to rush. You can then spend time looking round the grounds not something to rush. By the time we got up to the castle and round around 90 minutes had passed and we had to rush a bit
All tours are based on one hour, is what the guide said
1 hour Tour then you are free to walk around outside. The bus leavings every 5 minutes. Very convenient.
I believe our tour was about an hour. Then you can walk around the grounds on your own or head back to the bus pick up.
