Once again, you are in the middle of Austin and the trail goes under the freeway at one point. There is also that trash thing that you get in larger cities. Unfortunate, but seems to be a fact of life here. Not to discourage, we really enjoyed the trail especially starting from the Scottish Wood Trail entrance which took us by several small waterfalls. The first trip down there we started from Zilker Park and it rained about half the time we were on the trail. Wet limestone is very slick and we only went 2 miles one way on the trail that day before turning back due to the slippery surfaces.
Barton Springs is damned up at Zilker Park creating a 3 acre man made swimming pool which remains a constant 68 degrees year round. To cold for me but I'm sure refreshing in the summer months!
