Start at the charming 17th-century style Pelican Inn at Muir Beach in Marin and head up the chaparral-covered Dias Ridge. The five-mile trail loops across former dairy ranches and rises 700 feet. At every turn there is another dazzling panorama of the Pacific and the Marin Headlands. Parking is available at either end of the Dias Ridge Trail along Panoramic Highway at the top and Shoreline Highway at the bottom. Completed in 2010, the Dias Ridge project removed the old, eroded road, and created a new multi-use trail segment that better protects the Redwood Creek Watershed below.
