There is a robust recreation program at Harding/New Vernon, including Ski Club, Lacrosse, Basketball, Soccer, T-Ball, Field Hockey, and a 5 week Summer Camp as well! There is preference given to Harding Township residents as spots are limited, but there are openings for non-residents as well. They offer both 1/2 and full days for the camp! It starts after school ends, so the last week in June, and then the 4 weeks of July.
