Rockport State Park is a 632-acre day-use park and provides an extraordinary example of old-growth forest. The park’s ancient trees, having never been logged, form a landscape and ecosystem seldom seen nowadays, a canopy of towering evergreens so dense that minimal sunlight shines through. Breathe in the crisp smell of conifers and feel the earth beneath your feet, then look up and marvel at the Rockport giants, some more than 250 feet tall. The park stands at the foot of the climbable Sauk Mountain, elevation 5,400 feet.
