A bay cruise is a great way to get away from the city so you can enjoy its skyline. The traditional cruise goes around Alcatraz and under the Golden Gate Bridge, a nice trip that rounds out your San Francisco experience.
Pros and Cons
A bay cruise is a nice way to see the city from a different angle - and rest your tired feet. On a clear, warm day it's a real San Francisco treat. However, it can be cold on the bay when you'd least expect it, fog and cold, damp air can move in fast even in mid-summer and a moving boat makes it feel that much colder.
