Uncertain—that's what they call one of the Texas towns that thrives near the mysterious swampland landscape of Caddo Lake. In some ways, that says it all, as this is eerie, evocative terrain. A blend of backwater bayou and river, Caddo Lake stretches across the Texas/Louisiana border, and is home to creatures that range from armadillos and alligators to beavers and feral hogs; the waters also hold 70 species of fish. Caddo Lake State Park also offers 50 miles of kayak and boat trails, framed by cypress trees dripping with Spanish moss. A favorite route, Hell’s Half Acre, loops for 8.8-miles—and is especially atmospheric at sunset.
