You won't beat the views from the parking lot of Coit Tower and the surrounds. You could take the easy way out and drive up but the parking lot fills up fast and traffic gets dicey. Opt instead for a walk up the "hidden" steps from Sansome & Greenwich Streets. It's a beautiful walk through some secret gardens and unusual plantings and there's rumors of wild parrots. Didn't see the parrots on our trip. CAUTION: This is a pretty ambitious walk and a significant number of steps.
