This was a really beautiful and varied trail that was quite different to the surrounding areas

The suspension bridge and overlook to the river sink were nice. The 8 or so miles round trip to Sweetwater Lake was also nice. It is Florida so if hiking in the summer make sure you have plenty of water, sunscreen and bug spray.

This 3-mile loop trail takes you through a fascinating blend of landscapes. You'll traverse pine flatwoods, hardwood forests with towering American beech trees, and swampy areas along the tributaries of Townsend Branch Creek. Part of the West Trail overlaps with a section of Old Providence Road/Fort Call Road. This historic path was once used by early residents.

The preserve boasts a fascinating mix of ecosystems, including southernmost reaches of Appalachian hardwood forests, vibrant pine flatwoods, and even a small waterfall. This variety makes for a truly unique hiking experience. One of the most remarkable features of Mill Creek is the presence of American Beech trees. These magnificent trees reach their southernmost extent here in Florida, making the preserve a haven for those interested in unusual plant communities.

The trail roughly follows the underground path of the Santa Fe River. Starting at the park, you'll witness the very spot where the river plunges into the earth through a sinkhole. The trail then continues above the river's hidden journey for several miles.

Built during the New Deal era, it's one of the few suspension bridges remaining in Florida. As you cross, you can admire the scenic views of the Santa Fe River below.

July 19, 2024, River Sink

The crown jewel of O'Leno State Park is undoubtedly the River Sink. Here, the mighty Santa Fe River takes a dramatic turn and vanishes underground! The rushing water seems to be swallowed whole by a large opening in the earth's surface. It embarks on a subterranean adventure, flowing for over 3 miles beneath the surface.
