The Ward Spring Trail is a 2.9 mile out and back trail in Big Bend National Park. The trail takes you through the Chihuahuan Desert off the Ross Maxwell Scenic Drive towards the Chisos Mountains. At the end of the trail you will find a true desert oasis with small oak trees growing beside the small spring-fed creek. This hike is one of the many small things in Big Bend that makes the area so amazing. Also there are some pretty cool rock formations along the trail.
