We love this part of the Sam Houston National Forest, even if it is just a teensy bit outside of Montgomery County. The photos below are from the Lake Loop Trail, but it shares a parking area with the Sandy Trail, Fern Trail and Zebra Trail heads. So you can follow the link below for several different hikes!
