One of the many places I visited last Monday was Madam Brett Park in Beacon. The park has a variety of interesting locations along its relatively level one mile trail, including Tioranda falls and an observation deck to overlook the Fishkill Marsh. The boardwalk photographed connects you to the marsh while offering great views of the creek.
For more information on Madam Brett Park, be sure to visit this link on the Scenic Hudson website.
