Cape Cod & the Islands boast state and local parks with fun activities all year

This is a large camping park in the inland pine woods of Cape Cod. Swimming and fishing is done at eight fresh-water kettle ponds. Ponds are stocked year-round with trout. The park is filled with walking, hiking, and biking trails. An eight-mile bicycling trail within the park connects to the 22-mile Cape Cod Rail Trail, a former railroad bed now dedicated to walking and biking. Visitors may swim and canoe and kayak at Flax Pond; enjoy the wildlife or fish (catch-and-release) at Higgins Pond, or enjoy staff-led nature learning programs. Four hundred camp sites include yurt camping. You cannot see Cape Cod Bay from this inland park, but the bay is within walking or bicycling distance. - Trail Map (PDF)
