The Tassajara Zen Mountain Center in the Ventana Wilderness area of the Los Padres National Forest, southeast of Carmel-by-the-Sea, California, is the oldest Japanese Buddhist Sōtō Zen monastery in the United States. The Center is very isolated, more than 16 miles (26 km) from the nearest paved road, and only accessible via a narrow, steep, one-lane dirt road. During the winter months, practitioners live alone on site. During the summer months, the Center is opened to day and overnight guests. The hot springs have been developed into Japanese-style baths. It is the first Zen monastery established outside of Asia.
