For now, I'd like to let everyone know how to get to Airfield Falls (Fort Worth's only natural water fall). This is from a comment that the TRWD made on Facebook:
If you are looking for a trailhead in a close vicinity of Airfield Falls, TRWD has recently completed a trail access point from the Westworth Village City Hall (311 Burton Hill Road) to the Trinity Trails. You are able to park and use their water fountain and restroom facilities located inside City Hall. Attached is a map that will help you get to the falls from City Hall.
The contractor on the project has ceased work and has requested that TRWD make a transition from the contractor to the bonding company to complete the Airfield Falls Trailhead project. TRWD is in active communication with the bond company to complete the project as soon as possible.
