New Discovery State Park, State park in Marshfield, Vermont.

New Discovery State Park is a forested area in Vermont with lakes and mountains that spans several thousand acres. The landscape offers different recreation areas with camping zones and hiking trails through varying vegetation zones.

The park was created in the 1930s through a federal building program that built camping areas and trails. These historic facilities were added to the National Register of Historic Places in 2002.

The Civilian Conservation Corps crews were based at a camp whose foundational remnants still lie within the park. Their work shaped the campground, the picnic areas at Lake Osmore and Owl's Head, and much of the early trail network in the northern forest.

The campground splits into two areas: 46 tent/RV sites and 15 lean-to sites, seven of them set aside for horse campers, with hot showers in the restrooms. Remote lean-tos around Osmore Pond are reached only by boat or by the trail circling the lake. Route 232 runs through the park, and a CCC-built road climbs to the picnic area on Owl's Head summit.

Several overnight lodgings are only reachable by paddling across the water or hiking deep into the park interior. This sense of seclusion sets it apart from many other parks in the region.
