Get in


By car


Driving is the best means of getting into Karnack. Public transportation does not come through this area. There are two state routes that run through the small community.

  • Texas Highway 43, coming from Marshall or Atlanta. In Marshall, TX 43 connects with Interstate 20, which goes to either Dallas or Shreveport.
  • Farm Road 134, coming from Jefferson. This connects with US Highway 59, heading north towards Texarkana and the Arkansas state line.

By boat


If you have your own boat, you could come into Karnack via the nearby community of Uncertain. The other launching points on Caddo Lake, the towns of Mooringsport and Oil City, are on the Louisiana side. It is highly advisable to acquire a local Caddo Lake map prior to attempting to navigate the confusing array of boat trails that are on the Texas side. There are dozens of trails and an unguided boater could easily get lost.

Get around


Despite the community's small size, it is not suitable for walking as there are very few sidewalks; plus, most things to see and do are spaced out far enough that walking would not be convenient. Personal vehicle is the best method of getting around Karnack.

Another excellent option would be to catch your dinner out on Caddo Lake! The lake is well known for bass, catfish, crappie, and sunfish. If camping, a good local experience is a pan-frying catfish over a campfire near the lake. For the authentic East Texas experience, use pine for firewood.
