Because a considerable portion of San Francisco was built upon dunes, it's an accomplishment to have as much green space as we do. Both Golden Gate Park and the Presidio defied natural odds by sprouting forests where sand and grasslands dominated (with a bit of help from landscape architects like John McLaren, of course).

Our greenbelts also mean plenty of nature. Here are some of the places offering free nature walks and classes throughout San Francisco.

1. San Francisco Botanical Garden

The San Francisco Botanical Garden (at Strybing Arboretum) is 55 acres of plants and flowers representing a variety of climate zones.

The Botanical Garden offers free docent-led guided walks of the gardens (daily), as well as free birding walks, and family walks on various days of the month.

The Palo Alto Baylands offer spectacular bird watching during the winter migration months. They offer some guided nature walks, as well as good information on self-guided tours and walks of the park areas.

The guided and self-guided walks to see elephant seals at Año Nuevo State Park (south of Half Moon Bay) are a highlight of any Bay Area visit. During certain times of year, during mating and baby season, access to the elephant seals is restricted.

Fitzgerald Marine Reserve at Moss Beach is tide-pool nirvana. You can explore on your own (observing all of the careful conservation principles) or take one of the docent-led tours of the tide-pool area.
