Caddo Lake, straddling the Texas-Louisiana border, is a hauntingly beautiful maze of bald cypress trees draped in Spanish moss. As the largest natural lake in Texas, it was formed by a massive log jam on the Red River. The lake and its surrounding wetlands are a designated Ramsar Wetland of International Importance, offering paddlers and anglers an otherworldly landscape of dark, tannic waters and abundant wildlife, including alligators, herons, and the rare paddlefish.
Best season — Spring and fall for mild temperatures and lower humidity; summer is hot and humid with peak mosquito activity.

On the ground
Caddo Lake, located on the Texas–Louisiana border, is a significant Ramsar Wetland of International Importance. Formed by a historic log jam on the Red River, this approximately 27,000-acre area stands out as one of Texas’s few natural lakes. The lake’s unique ecosystem supports over seventy fish species and wildlife like alligators and herons within its cypress swamps and bayous.
RV travelers to Caddo Lake primarily experience the landscape from the water. Canoeing and kayaking are popular ways to navigate the maze of waterways, offering views of the draped bald cypress trees. Fishing for largemouth bass and crappie is also common. A two-mile forest trail provides hiking opportunities within the managed state park, while nearby towns offer guided tour options.
The most favorable times to visit Caddo Lake are spring and fall when temperatures are mild and humidity is lower. Summer months bring hot, humid conditions alongside increased mosquito activity. Planning a trip with these seasonal considerations will enhance comfort during outdoor activities like paddling or fishing on the lake’s surface.
Consider establishing a basecamp in the Karnack area for exploring Caddo Lake. This location provides convenient access to both the state park and points along the lake's edge. From there, daily excursions can be made to experience the unique cypress swamps and bayous by kayak or to fish its waters, returning each evening to your RV site.
