Big Talbot Island State Park is a Florida State Park located on Big Talbot Island, 20 miles east of downtown Jacksonville on A1A North and immediately north of Little Talbot Island State Park.
The park is a nature preserve and a location for nature study, bird–watching, or photography. Other activities include hiking, bicycling, fishing, boating, canoeing, kayaking, and picnicking. Amenities include picnic pavilions, nature trails, a fishing pier, a boat ramp, bike trails and beaches. The park is open from 8:00 am till sundown year round.
The coastal landscape and beach at Big Talbot Island is unique within the state of Florida as result of the lava like hardpan sedimentary deposits. These rocky formations are habitat for mollusca, crab, oysters, and other tide pool creatures. The formations and sand on Blackrock Beach are much darker in contrast to the coquina formations at Washington Oaks State Gardens, and the limestone outcroppings at Blowing Rocks Preserve further south on A1A. The beach can be accessed through the park entrance or through the trailhead parking area adjacent to the Blackrock Trail.
