Somerville Trailway Professional Review and Guide
"A long, easy ride through flat and piney East Texas woodlands, the Somerville Trailway connects the Birch Creek and the Nails Creek units of Lake Somerville State Park. This is a good beginner’s trail, as it offers a place to put in some long miles without any serious technical challenges. The beauty of this trail is something like the beauty of the midwestern prairie—it’s there, but you gotta let yourself appreciate it.
Ultraflat, grassy, and stretching out as far as you can see, the open distance makes for windy days and gigantic skies. Don’t be misled, though: The length of the trail and the fact that there’s not much opportunity to coast make this ride deceivingly tough. You will get a workout. Tread: Mostly doubletrack, with some singletrack and some wide gravel path."
