Marietta’s unique location allows the Valley Gem to offer a variety of Lock and Dam tours. Along with other longer extended tours, we are also able to offer shorter tours through Devol’s Dam on the Muskingum River and Willow Island Lock and Dam on the Ohio River. The Portside Café will be open on the boat throughout the trip if you wish to purchase refreshments. You can also pre-order a bag lunch that will be ready when you arrive.
