The trailhead to Thrall Dam Park can be easy to miss if you don't notice the brown metal sign and somewhat hidden dirt road that leads into the woods, then opens up into the parking area. This park has over 500 acres with seven trails that lead hikers through beautiful forested areas. It also offers nice brook trout fishing in the pond. It was a project made possible by many generous volunteers, the Town of Lewis and county Healthy Schools and Community grant funds.
