Big Thicket was the first national preserve in the United States, established in 1974 to protect not one landmark but a meeting of worlds. Here, multiple ecosystems converge, from longleaf pine forest to cypress-lined bayous, spread across 113,114 acres in seven counties. The result feels nothing like Houston two hours behind you. Start at the visitor center near Kountze to fill water bottles and get trail advice, then pick from more than 30 miles of hiking trails. The Kirby Nature Trail carries you on boardwalks through dense, green thicket, and some savanna trails are known for carnivorous plants like pitcher plants. Paddlers can slip into creeks, bayous and the Neches River. Entry is free, the crowds are thin, and the silence is the real souvenir. Pack insect repellent, sturdy shoes and a picnic, since services inside the units are few.
