This week, park-loving San Franciscans should be turning out in force when the board of the Presidio Trust meets to hear public comments on the three development proposals in play for Crissy Field.

The busiest unit in our national park system isn't a park at all. In fact, plenty of visitors never notice that they're in it — not when they're half-lost in the redwoods of Marin County's Muir Woods, not when they're deep into a conversation about robots at San Francisco's Ft. Mason, not when they're roaming the vast beach flats of Ft. Funston, near the San Mateo County line.

The flower beds that once served as colorful buffers for the notorious former prison site known as the Rock have been restored thanks to the efforts of the Alcatraz Historic Gardens Project.

Alcatraz beat out the Golden Gate Bridge, the Lincoln Memorial and the Statue of Liberty to be selected the No. 1 landmark in the U.S. in TripAdvisor's recent Travelers' Choice awards.

Cavallo Point the Lodge at the Golden Gate just earned LEED (Leadership in Energy and Environmental Design) Gold (the second-highest level of certification, after platinum) certification from the U.S. Green Building Council. The Gold certification applies to the entire lodge project, including its historic and new buildings and the overall site. The project's green elements include its use of solar panels in its metal roofing; low-VOC glues, paints and carpets, and materials such as bamboo and recycled wood.

Tours of the Golden Gate Bridge inaugurated during its 75th anniversary in 2012 are back for a second season starting April 1, 2013.

The historic Round House building at the Golden Gate Bridge will soon re-open as a cafe, closer to its original use when it opened 77 years ago.

Wildlife cameras installed on Mount Tamalpais’ watershed and surroundings in late 2014 have turned up rare glimpses of the creatures that inhabit Marin’s wildlands.

Endangered species transferred from creek to hatchery until habitat improves

Ten years ago, the Garden Conservancy, whose mission is to preserve exceptional American gardens, in partnership with the Golden Gate National Parks Conservancy and the National Park Service, decided to restore the Alcatraz gardens after decades of neglect.
