if you're in a mood for a small hike then this is an ideal spot. Accessible even by walking from Kintetsu Nara. Great view of the city from the top and many deers to play with everywhere on the hill. The hike was reasonably ok for an average fit person. Although I did see some people struggle to climb to the summit during the summer heat (was 37C on that day)! In good weather the climb would have been much easier. Regarding the opening hours, I believe entry closes at 5pm but you don't have to get off the hill by then. You can enjoy the night view from top and when you come down you can head to the central exit where you can go out via a one way rotating exit gate.
