Big Thicket National Preserve is a biological crossroads in Southeast Texas where five distinct ecosystems converge, including pine savannas, cypress baygalls, and hardwood forests. Spanning over 113,000 acres, the preserve is designated as an International Biosphere Reserve by UNESCO. It features an extensive network of over 40 miles of hiking trails and multiple waterways for paddling. The preserve is noted for its high biodiversity, housing over 1,000 species of native plants and rare carnivorous plants. Water-based recreation is facilitated through access points on the Neches River and Village Creek. It is managed by the National Park Service as a protected area rather than a traditional national park, allowing for regulated hunting and trapping. Wildlife observed include American alligators, river otters, and over 300 bird species. Visitors can explore various units of the preserve scattered across several counties.

Wear long pants and closed-toe hiking shoes to protect against thorns, poison ivy, and ticks; stay on marked trails to protect sensitive ecosystems.
