Hiked the Elm Creek Nature Trail with my kids. It was a beautiful March morning. The trail is a very easy hike, fairly level and I would guess 1.5 to 2 miles. According to my GPS we hiked a little over 3 miles, however over a mile of our hike was on park roads from our camp site. The TP&W map is not quite accurate showing the trail. When you get to the gravel trail go straight across it and continue down the dirt trail. Although we met no other hikers on the trail, I gave it a 2 for solutude due to the trafic noise we could hear from the nearby highway. If you are camping in Abilene State Park, I would recommend taking this hike.
