Fishing, swimming, mini golf, and a jumping pillow give families a lot to work through at Williamsport South-Nittany Mountain KOA, a KOA-operated campground in New Columbia, Pennsylvania, open from April 1 through November 1. Most sites are wooded and gravel-surfaced, with pull-through and back-in options accommodating RVs up to 85 feet. Full hookups including electric, water, and sewer are available, and the camp store stocks fresh eggs, ice cream, and made-to-order pizza. A fishing pond sits on the property, and a petting zoo gives younger campers a reason to wander.
Site quality varies. One reviewer noted that a pull-through site ran uneven front to back, requiring the tongue jack to be extended fully to achieve level, and that the gravel pad was narrow enough to put the picnic table within two feet of the trailer wall. Side-to-side leveling, however, was not a problem. Wooded sites provide decent shade, and several long-term seasonal campers occupy a portion of the grounds, which shapes the campground's settled, family-oriented character. Weekends draw more activity, particularly during themed events. John T. notes that theme weekends "will be crowded and there could be an additional fee," citing a $20 charge during Care Camp Weekend.
The bathhouse earns consistent marks for cleanliness, and the swimming pool is well-maintained according to multiple visits over several years. Golf carts are available to rent, which means some road traffic moves through the campground. Cell service and WiFi both come up as reliable in recent reviews. A farmers market in nearby Lewisburg runs on Wednesdays, giving campers a short drive for local produce. The campground sits close enough to I-80 and Route 15 to function as a convenient overnight stop for travelers passing through central Pennsylvania, and campsites near New Columbia span a range of styles for those planning a longer stay in the region.
Halloween weekends in October draw repeat visitors specifically for the seasonal programming. Hidden Creek Campground is another option roughly six miles north for campers who prefer a quieter, less activity-focused setup.
