Exit 680 at Alcosta Blvd., take Alcosta to right turn on Old Ranch Road, Baskets will be on your left, directly across from Old Ranch Park, about half way between Alcosta Blvd. and Dougherty Road. Park in the Old Ranch Park parking lot and cross Old Ranch Road. There is a concrete path leading into the course near the cross walk. First Tee is chalk marked on the concrete path near the first elbow in the path. First basket is up to the right. Most of the Tees are chalk marked on the path, a couple of them are roughed out dirt pads. The course goes back and forth up the hill with basket 9 on the plateau at the top of the hill.
I played the course on Friday and bumped into Greg there. As he said, windy and very compact course, brand new baskets. Not a lot of trees, mostly grassy hillside.
Give huge thanks to Mike Tower for getting another Contra Costa course in. Mike is a Moraga Disc Golf regular.
