Plymouth Long Beach is a great and beautiful beach for long walks, finding rocks and sea glass, or bringing dogs. The large parking lot costs $20 during summer, with weekend visitors advised to arrive by 9:30. The beach has easy access bathrooms, facilities, and a cash-only restaurant that is delicious and good value. The sand is pebbly and rocky at the front near the parking area, with stones under the water, so water shoes are recommended. Beyond the large rock patch, it becomes all sand. For a long walk, check the tides and aim for low tide. The beach offers an awesome fireworks view. Some visitors note a need for more trash barrels to prevent overfilling. It is busier in summer but much quieter in the off season.
