Meet at the Barton Creek trail head that is off the Barton Skyway Mopac entrance, roughly halfway between the Colorado River and where 360 crosses Mopac south of that. From Mopac going south take the Barton Skyway exit, turn left and park near where it dead ends around Taco Deli.
We will hike 2.5-3 hours at most and will climb up and go along the cliff when the path is close to the cliff. There is the stone bridge to optionally cross, plus two or three great panoramic views. If you have not already done this hike it is not to be missed.
The creek bed is likely to be dry for the complete segment we will be coming back on and the hill segment has no water, so bring water for dogs if you have them and for yourself definitely. Good shoes, good attitude all important.
