Bicycle Austin forum

Hey Folks.  I am moving to Austin and looking into where to live

1. is it possible to bike or even walk from Travis Country Circle down to the Barton Creek Greenbelt trail?  Austin bike map shows this trail on the NE side of the creek in that area, would I have to cross the creek if I was able to get to the creek from Travis Country?

2. Again, from the Austin Bike Map, all of MoPac near Barton Skyway is shown as RED "Low Ease of Use".  But I have driven the frontage roads there and they seem OK (I am OK with 50 MPH cars nearby as long as I have a good shoulder).  BUT am I right in seeing no frontage road where Mopac crosses Barton Creek?

3. Question unrelated to Travis Country : how hard is it to ride or hike across Barton Creek Greenbelt from the Lamar section of Barton Skyway to the Mopac section of Barton Skyway?

THANKS!
