Overview

Marathon Lake Loop circles a small reservoir in the northern section of Bienville National Forest, offering 4 miles of easy walking with consistent lake views and fishing access. The trail is the quieter alternative to the Lake Mike Conner loop in the same forest, with a smaller lake and more basic facilities that suit visitors seeking a less developed recreation area. Vault restrooms at the campground are the main facility.

No permit is required. The terrain is flat and the trail is well-maintained. October through April is the most comfortable season.

The Route

The loop: The trail circles the lake in a consistent counterclockwise direction, maintaining close proximity to the shoreline throughout. The pine-hardwood forest comes close to the water in most sections, with a few open areas near the dam and inlet that offer the best birding opportunities.

The loop is consistently flat with clear trail markings. The total 4 miles returns to the campground parking area.

When to Hike

October through April is the most comfortable period. Fall and winter waterfowl on the lake are a highlight. Spring brings woodland songbird migration through the surrounding forest.

Summer mornings: The loop is manageable before 10am even in summer heat.

What to Bring

Carry at least 1 liter of water; the lake is not suitable for drinking without treatment. Binoculars for lake birding. A fishing license and tackle if planning to fish.

Trailhead Access

Marathon Lake Campground is reached via forest roads in the northern section of Bienville National Forest. The access road is unpaved and passable with standard vehicles in dry conditions.
