Campgrounds and RV parks near New Castle, IN

Water activities anchor most trips. Summit Lake State Park has three boat ramps, a swimming beach open Memorial Day through Labor Day with a modern bathhouse, and boat rentals including paddle boats, row boats, and canoes; the entire lake is idle-speed only, which keeps things calm for paddlers and anglers. Westwood Park limits its 180-acre lake to electric trolling motors, producing unusually clear water for bass, bluegill, crappie, and catfish. On land, Westwood Park has a roughly 10-mile trail circling the lake for hikers and mountain bikers, plus a separate horse trail. Summit Lake has four easy-to-moderate hiking trails and strong bird-watching, with sandhill crane, bald eagle, and osprey among the notable migratory species. Off-property, families often add the Indiana Basketball Hall of Fame in New Castle and the Wilbur Wright Birthplace and Museum.

The camping season in this part of Indiana runs primarily April through October. Westwood Park's campground is open May through October, and Yogi Bear's Jellystone Park Camp-Resort: Knightstown operates roughly from early April into early November with themed weekends throughout the season. Summit Lake State Park's campground stays open year-round, though most properties turn off water, close modern restrooms, and winterize full-hookup sites from November through April. Late spring and early summer bring the wettest weather, and thunderstorms are common from May through June. Peak demand runs from Memorial Day through Labor Day and around the July 4 holiday, when lakeside sites at Summit Lake and pull-throughs at the Jellystone resort fill early. Blue-green algae advisories can appear on Indiana lakes in warm months, so check Indiana DNR alerts before swimming. September and October offer cooler nights, thinner crowds, and fall color in the oak-hickory woods. Winters are cold, with camping still available at Summit Lake at reduced amenity levels when conditions allow.

Sites at Summit Lake State Park have electric and water hookups with modern comfort stations; water spigots are often shared between neighboring sites, so pack a longer hose. Two loops offer either open, level sites or wooded sites on gentle slopes, and rangers enforce quiet hours and site rules closely. Westwood Park's Point Campground has 38 sites with individual water and electric hookups plus a nearby dump station. Sites are compact but generally accommodate rigs up to about 40 feet, and there is no sewer at the site. Yogi Bear's Jellystone Park Camp-Resort: Knightstown offers full-hookup pull-throughs with 30 and 50 amp service, a swimming pool, stocked fishing lake, and organized daily activities. Firewood brought from outside Henry or Hancock County is not permitted at the Jellystone resort, so plan to buy local wood on arrival.
