Plymouth Rock is located in Pilgrim Memorial State Park on the shore of Plymouth Harbor. The rock itself, a symbol of where the pilgrims first landed in the U.S., is actually quite small and surrounded by walls and railings. The rock is worth seeing for its historical significance alone, but once in Plymouth, you can visit the Mayflower II, explore the historic district, and enjoy shopping, dining, or all that the waterfront has to offer. Plymouth is great for families and has much to offer from informative museums to exciting whale watches.Parking and public transportation at Plymouth RockThere are plenty of parking options including free and metered lots. Most lots have a ten hour maximum and charge by the hour. Meters on streets near the waterfront generally have two to four hour maximums.
