Hidden Valley is a ski resort located in Vernon Township, New Jersey off of County Route 515, near the intersection with Route 94.

The mountain's top elevation is 1,435 feet above sea level and bottom elevation is 815 feet, with a vertical drop of 620 feet. The resort has 15 trails - 25% Beginner, 30% Intermediate and 45% Advanced. The longest trail is "Browse Along" (3/4 Mile). There are five lifts, one triple, 2 doubles and two surface lifts. Uphill capacity is 3,500 per hour. In 2007 the resort, after years of struggling to compete with the nearby and much larger Mountain Creek, declared bankruptcy and was sold at a sheriff's auction. The new owners are keeping it open.
