"This ride is a pedal-powered introduction to San Francisco’s avian life. Riders will look for some of the more than 300 resident, migrating and overwintering bird species that can be found in SF, proceeding at a relaxed pace around Lake Merced, to Ocean Beach, the Cliff House and Golden Gate Park. The tour will finish at Crissy Field in the Presidio where riders will look for ducks, waders and shorebirds. All skill levels are welcome, and please bring binoculars."
