In addition to hosting rare plants and habitat for a diversity of birds, it offers extraordinary nature-based recreational opportunities. West Rock Ridge is a wonderful park to visit.

- The ridge at West Rock is a basalt rock of volcanic lava origin commonly called traprock. This term is derived from the rock’s stair-like appearance, clearly visible on the western slope.
- The rock dislodge from the slope is called talus. It piles at the base providing good cover for small mammals and reptiles.
- West Rock’s gently sloped eastern side is referred to as a dip slope.
- The summit supports an uncommon ridge top plant community dominated by hickory with a sedge understory. On the upper dip slope, shallow bedrock outcrops create open woods with red cedar and an understory of little bluestem grass. Downy arrowwood is one of the rare plants that grows in this habitat.
- The rocky talus areas at the toe of the western slope collect organic matter creating a rich soil. Some of the uncommon plants here are American bladdernut, round-leaved dogwood and jack-in-the-pulpit.
- West Rock Ridge hosts 230 species of birds, the highest percentage of breeding birds and the second highest concentration of rare species of any Connecticut state park.
- Look for one of the park’s four vernal pools when exploring West Rock in the spring. Vernal pools are natural depressions in the landscape that are dry most of the year, but fill with water each spring. They provide critical habitat for amphibians.
- Hike the extensive trail system suitable for varying skill levels. Many of the trails offer stunning views of New Haven Harbor and Long Island Sound. Print and bring a convenient one-page trail map.
- Camp at the nearby West Rock Nature Center, using your own gear or borrow gear from the nearby Common Ground School.
- Explore Judge’s Cave, off the Regicides Trail, where two British judges famously fled prosecution after the English Civil War in the 17th century.
