High Point State Park Professional Review and Guide
"This dated north-south forest road trail rests along the crest of the Kittatinny Mountains located in Sussex County in the northwest corner of New Jersey. It passes through a very scenic forest packed with oaks, hickory, red maple, white ash, and young chestnut. The 14,056-acre state park is tantalizing, with its breathtaking scenery and breath-stealing doubletrack. High Point State Park within the Kittatinny Mountains boasts New Jersey’s highest peak, High Point, at 1,803 feet, and a challenging doubletrack trail system. The dominating part of this tour is the 5-mile (one-way) Iris Trail.
The not-too-difficult Iris Trail runs through deep woods on abandoned logging and farm roads that have resulted in rugged trails. The route serves as a popular snowmobile and cross-country ski trail in the winter. This tour is not for the weak of heart. Keep a light touch on the brakes; the trail requires some technical handling as you traverse the rocky surface of the eroded roadbeds."
