Available Nov 13–15 · 2 nights78 sites open for every nightA forested campground near fishing, and hiking.
Marathon Lake sits in Smith County around a 50-acre impoundment that carries the name of the Marathon Lumber Company, which closed in 1929. The recreation area centers on a small sandy beach and a boat launch, and the lake is stocked with catfish, bass and crappie (bream fishing is allowed), so anglers find plenty to do from shore or a small boat.






Length limits vary by campsite.
Some sites have no hookups.

“This camp ground was soooo peaceful and quiet.”
Gary J ★ 5 · Oct 2025Wonderfully quiet. Clean and well kept
Trae R ★ 5 · Mar 2025Love staying here! Beautiful place.
Teresa B ★ 5 · May 2024This camp ground was soooo peaceful and quiet. It seems like its in the middle of nowhere, which was great but also slightly creepy because I was all by myself. I stopped on my way to and from Texas for an event. I will drive the 12 hours again to go to this camp ground again. Almost nooooo cell service so know that and be prepared before you arrive. If you like to fish, definitely bring your gear to fish.
