West Austin Neighborhood Park (1317 W 10th Street) is a three acre Clarksville-area park with interesting topography and a bit of a skyline view. It’s hilly landscape gives a nice little running challenge. Running out and back on the sort of U-shaped perimeter (plus out and backs on the mixed-surface walkways through the middle) twice yields one mile.
There is a dog park here and a pretty swimming pool (open 1pm-6pm Tuesday-Sunday currently), along with a playground and picnic areas. Ample street parking is available, and the park was heavily trafficked by dog walkers when I visited yesterday. Even though there’s not a huge area to run here, the scenery makes it worth the visit in my opinion.
