White Clay Creek State Park near Newark covers about 3,700 acres of creek valley along the Delaware and Pennsylvania border. Rolling hills, hardwood forest and open fields make it one of the most scenic places for outdoor recreation in northern Delaware. The park has around 37 miles of trails for hiking, running, mountain biking and horseback riding, and the creek itself offers fishing and quiet scenery. The historic Chambers House adds a glimpse of the area's farming heritage. Admission is $4 for Delaware residents and $8 for out-of-state visitors on weekdays, and $8 and $16 on weekends, from March through November. The size and variety of trails make it a great destination for repeat visits.
