The panoramic elevator offers great views of Corunna. From there, you can see the Millenium, Orzán and Riazor beaches, and of course, the Tower of Hercules. There are normally lines to go up and down (although you can always walk down). It goes up on the hour, and down on the half hour. You have to be smart once inside the "ball" if you want a good view. When we were there, it had just opened and it didn't cost anything.
