Alcatraz, San Francisco, California
Concierge.com's insider take:
Surrounded by icy water and treacherous currents, Alcatraz was an ideal site for a high-security prison, and unsurprisingly, nearly all of those who tried to escape were caught, shot, or drowned. Enjoy a chilling tour of the jail, closed in 1963, and while strolling the exercise yard, imagine how the dazzling view of San Francisco must have tantalized inmates. The ferry departs several times daily from Pier 33. In peak season, book in advance by calling 415-981-7625, or go to www.alcatrazcruises.com.
