The hill that dominates the city from which you have a good view of the whole area. It's not a very steep climb from the bottom. Sunrise and sunset are the most sensible and rewarding times to go. There is a near-panoramic view from the top. The ticket office closes at 18:30, so climbing to the top is virtually free afterwards, which gives you about 30 minutes before it gets dark. This is not the place to go however if you are looking for a romantic sunset with not so many other people around. In this case go to a remote section of the shoreline or book a sunset tour on a small boat.
