Golden Gate Bridge
I took a ride on the "Adventure Cat," a catamaran that gives tourists ride out beyond the Golden Gate Bridge and back. A great alternative to the ferries; small (maybe 25 people tops?), wind powered, just delightful in every respect.
$25 for an hour and a half ride, $12 for kids; children under five ride free.
They sail out of Pier 39, and will be open until about December 1. for reservations: Carol, (925) 258 9711
