"Hiking - Hiking is a popular way to enjoy the forest and its beauty. The 128-mile Lone Star Hiking Trail, a portion of which has gained National Recreation Trail status, winds through the Sam Houston National Forest. The trail, marked with two-inch by four-inch aluminum markers to guide hikers, has recreation areas available at three different points. Except during deer hunting season when camping is restricted to designated camps, primitive camping is allowed off the trail. "
