We got there during a weekday in slow spring season. There were no cruise ships in port which means we got the whole place to ourselves. It was free to access, and you can go up the theatre. If left unmaintained, nature easily takes over. You can see pics online of what it looks like when the grass is cut.
Toilets were closed when we got there. Not much historical facts to read. However, the site is on the side of a main road and worth a quick stop.
