Nice, short hike down the hill from Battery Godfrey to Marshall Beach, mostly stairs. No pets allowed. Plenty of plants and birds to see. Breathtaking views all the way down the hill. It's a coastal trail, so it can get a bit windy and chilly. If you are driving, park at Lincoln and Langdon Streets at Battery Godfrey and pick up the trail there.
