Crissy Field is an incredible place to walk, run, or just hang out and take in the GG Bridge and SF views - and maybe grab a coffee from the warming hut on west beach. Once an abandoned military airfield only used as a launching pad for windsurfers, the reconverted wetlands is now a part of SF life. Windsurfers still take off from the east beach though, as do kitesurfers! #crissyfield #sanfrancisco #running #urbanhikes #urbanparks #sanfranciscohikes #hiking
