The Big Slough Trail is five-eighths of a mile in length and loops back to its beginning near the boardwalk. While about 45 minutes are needed to cover the entire trail, three shorter trails cut across the main loop to allow shorter hikes. Rest stops and observation platforms can be found along this flat trail. Don’t veer from marked trails and bring water, sunscreen, and insect repellant. A Big Slough Auto Trail is also available at the Brazoria National Wildlife Refuge.
