Step into the adventurous world of the Kolb Brothers at the “Amazing Kolb Brothers Exhibit” inside historic Kolb Studio — a dramatic house-turned-museum clinging to the edge of the canyon in Grand Canyon Village. Examine antique cameras used by the pioneering photographers, view paintings inspired by Grand Canyon landscapes, and watch the brothers’ groundbreaking 1912 motion picture travelogue documenting their river journey down the Colorado River through Grand Canyon. Saved from demolition in the 1960s, Kolb Studio remains one of the park’s most recognizable landmarks. Today, it serves as a museum, art gallery, bookstore, and gathering place for visitors near the start of the Bright Angel Trail. Operated by the park’s nonprofit partner, Grand Canyon Conservancy , the studio offers books, artwork, gifts, hiking essentials, park information, and the “Amazing Kolb Brothers Exhibit,” celebrating the lives and adventures of two brothers who helped shape Grand Canyon history. This summer, visitors will also have a rare chance to go behind the scenes as Grand Canyon Conservancy Field Institute guides lead special tours of the historic house and photo studio. Stay tuned for tour details.

Nike Missile Site Open House is the first Saturday of every month . Rangers and volunteers - including veterans of the Nike program - come to the site to share their stories with visitors. Guided tours are offered at 12:15PM, 1:15PM, and 2:15PM. The SF-88 Nike Missile Site is the most fully restored Nike missile site in the country. During the tense years of the Cold War, from 1953 to 1979, the United States Army built and operated close to 300 Nike missile sites in the United States. These sites were designed to be the last line of defense against H-Bomb carrying Soviet bombers that had eluded the Air Force’s interceptor jet aircrafts. SF-88 in the Marin Headlands was one such site. Today, Golden Gate National Recreation Area works together with a dedicated group of volunteers to preserve the site as it was during operations to remind visitors of the physical and psychological effects of the Cold War on the American landscape. The only restrooms available at Nike are Port-a-Johns. However, about a mile before the Nike Missile Site on Field Road is a larger rest-stop / parking lot with larger restooms and running water. It is recommended to stop and use these if needed, prior to arriving to Nike. For more information, please email GOGA_MarinHeadlands_Info@nps.gov

Open the first Sunday of every month (12pm - 4pm) Tours are given periodically throughout these open house hours Battery Townsley, at Fort Cronkhite, was San Francisco's most extensive—and most secret—World War II military fortification. From 1940 to 1948, it mounted two massive battleship guns and housed more than 100 soldiers in an extensive network of underground tunnels; during the Cold War, it was used as an underground research facility. Long closed to public access, Battery Townsley has been refurbished thanks to volunteer labor and community contributions and is now ready for tours. The public is invited to visit and explore this labyrinthine fortification! In fall 2012, the park brought to this site a 16-inch gun, from the USS Missouri . The gun, identical to the one that was once mounted at Battery Townsley, helps tell the story of the coastal defense system that later gave rise to these parklands. Learn more about this new addition . Battery Townsley is reached via a moderately strenuous hike up the Coastal Trail, approximately one-half-mile north of the Rodeo Beach parking lot. For more information, and further assistance to the site, please email GOGA_MarinHeadlands_Info@nps.gov
