Summary

Unique for its "ghost trees"—bald cypress over 1,000 years old—this area offers scenic boardwalks and wildlife viewing, especially for birdwatchers. Open year-round with no entry fee, it's best visited in spring or fall for vibrant scenery and active wildlife. Top highlights include the Heron Pond Trail, canoeing the Cache River, and spotting prothonotary warblers. There are no waterfalls or iconic formations, but the swamp’s eerie beauty makes it truly unforgettable.
