About Greenwood Lake Dam NRHP
Greenwood Lake Dam is a National Register of Historic Places-listed dam that impounds Greenwood Lake, a 6-acre lake inside Greenwood Furnace State Park in Huntingdon County, Pennsylvania. The lake was originally built in 1842 to power a gristmill for the historic Greenwood Furnace ironworks village, and today the state park operates an official swimming beach on it, turning this small historic impoundment into a proper swimming hole and a quiet lake to swim in.
The swim spot sits within the historic district of Greenwood Furnace State Park, a former 19th-century charcoal ironworks complex (operated 1834-1904) now preserved with a furnace stack, blacksmith shop, and CCC-era park development, surrounded by the 80,000-acre Rothrock State Forest along PA Route 305 about 5 miles west of Belleville, PA.
Swimming at Greenwood Lake Dam NRHP
Swimming takes place at a 300-foot sand beach on the small (6-acre) dam-impounded Greenwood Lake. It is an unguarded, DCNR-managed swim area (no lifeguards posted since 2008 per park history) suited to casual, low-key lake swimming rather than deep-water or current-driven swimming.
How to get to this swimming hole
The park is located along PA Route 305, about 5 miles west of Belleville, PA, at 15795 Greenwood Road, Huntingdon, PA 16652; it is roughly 20 miles from Lewistown, Huntingdon, and State College. Parking is available in the day-use area near the park office/Pine Pavilion, close to the beach.
Parking: Parking is available in the day-use area near the park office and Pine Pavilion, which also has a two-plug EV charging station; no separate beach parking lot size was specified in official sources.
The walk in
No real hike here. The water is a short walk from where you park. This is a drive-up beach in the day-use area next to the park office/Pine Pavilion parking lot - no hike is needed to reach the water. For visitors who want to walk, the 0.3-mile Lakeview Trail (rated 'more difficult' despite its short length) loops the lake past the ADA fishing pier and ends at the historic dam, but it is a scenic add-on, not the access route to the beach.
Plan your visit
Bringing kids
OK with supervision
The 300-foot sand beach has an ADA-accessible swimming ramp suggesting a gradual, sandy entry suitable for young kids, but the beach has been unguarded (no lifeguards) since 2008 and is officially posted 'swim at your own risk,' so close adult supervision is needed rather than relying on staff oversight.
Parking
Lot
Day-use parking is in the lot near the park office and Pine Pavilion, a short walk/drive from the beach; this lot also has a 2-plug EV charging station. No fee amount is published on official pages, and no beach-specific lot size is given.
Restrooms
Yes
A modern shower house, dressing area, and seasonal snack bar sit adjacent to the beach; separate modern restrooms with potable water are also located at the Lakeview Trail trailhead by the lake.
Hours
Park grounds open daily sunrise to sunset (day-use areas close at dusk). The swim beach itself operates late May through mid-September, 8:00 AM to sunset. Park office hours are 8:00 AM-4:00 PM, Monday-Friday.
On the water
Restrictions: Only non-motorized canoes and kayaks are permitted on the 6-acre lake; no motorboats. Craft must be hand-launched at a small access point next to the ADA swimming ramp at the beach (no boat launch/ramp for trailered boats). Boating is prohibited during the opening weekend of trout season. Non-powered boats must display a boat registration, a state park launching/mooring permit (available at most park offices), or a PA Fish and Boat Commission launching permit; standard PFBC boating regulations apply.
Official park pages do not mention paddleboards specifically, only canoes/kayaks, so paddleboard status is unconfirmed (unpowered paddleboards would likely fall under the same non-motorized rule but this is not stated outright).
Backstory
The lake was built in 1842 to supply water power for a gristmill serving the Greenwood Furnace ironworks, which operated from 1834 to 1904 as a charcoal-fueled ironworks employing about 300 workers. The dam itself was listed on the National Register of Historic Places on May 11, 1987 (NRIS #87000050). The state acquired the land in 1906 for a forest tree nursery, and the site became a public recreation area starting in 1924, with CCC improvements in the 1930s.
