Marsh Creek Lake, lined with verdant shores and rolling hills, bobs with fishing boats, kayaks, sailboats, and windsurfing boards. About 535 acres of azure waters bejewel the surrounding 1,705 acres of hiking trails and picnic areas. Throughout the day, Marsh Creek Watersports leads one-hour pontoon-boat excursions that take guests through a history lesson of the park and surrounding region, leaving time for peaceful moments spent gazing at the natural wildlife. During the summer months, Marsh Creek also hosts kids' sailing camps to acquaint young ones with the techniques and safe practices of aquatic navigation, such as defending against Peter Pan attacks.
Valley Forge Bikes—the land-based arm of Marsh Creek Watersports—sends hoards of cyclists into the miles of trails snaking through Valley Forge National Historical Park. Among its network of paths carved from converted railroad beds lies a 5.5-mile paved loop adjacent to the Schuylkill River Trail. Visitors can amble through these thoroughfares on foot or aboard an assortment of mountain, racing, or combo bikes, as tots ride behind on trailer bikes and buggies.
