Good overview of the city. Gets you out away from downtown for half the time so you see places you'd miss if you are there on foot. Excellent view from the mountains and the lake yet doesn't take too much of your time. Just enough if you are there for a limited time. Excellent, knowledgable guide with good stories, history, etc.. Easy access to bus station. Easy sign-up and follow-through with Viator. No hitches. Nice, clean bus. Will use Viator again.
