We skipped the walking tour of the city(which we normally do not do) and took off on our own.   We walked a bit through the city center, then got on a point to point trolley that went across the river and up a mountain side to a lookout area that included a church, an underground cave attraction and a gift and snack shop.   We got fantastic views and some really great deserts up there.  The trolley ride itself gave us some great views of the city.
