I love running the trail from the MoPac access road to Sculpture Falls and back. My dog loves it too. Yesterday we ran into exactly 4 other parties, 2 of whom had dogs as well. The water was shallow but clean, clear and cold. My dog loved it. The sky was overcast so the birch trees really stood out. Fantastic. Time given includes hanging out at the falls - probably :30 otherwise.
