I parked in the back of Krieg fields and hiked the Country Club Trail as well as the trail mentioned here--- going through Pleasant Valley tunnel and hiking a few miles with on the Lady Bird Trail.  I had never seen the Colorado River from this vantage point  (other side of dam) and really enjoyed the Buffle Heads and other ducks that were circling in the water below. Lots of trash everywhere and grafitti giving it a definite flavor.  It is nice to check out new places, and this will be a one time visit for me here.
