The group campsites have pit toilets. There are flush toilets and showers at Lake Marcia near the monument. The monument is a tall building built on the highest point in the park. It had been closed for repairs for a long time, but I recently heard a rumor that it reopened.
Driving directions: Take Interstate 80 West to exit 53 and get on New Jersey Route 23 North. After you drive a while on 23, you'll pass the town of Sussex. The park office is 7 miles north of Sussex. To get to the group sites, continue north on Route 23 past the office and make a left onto Sawmill Road. Then bear right onto Ridge Road. The group campsites will be on the right.
Address: 1480 State Route 23, Sussex, NJ 07461
