Not too many GPX files for that area floating around. You'll see a piece of single track on the left maybe 500 meters after leaving the clubhouse... hop on that and look for white signs with red arrows. Someone has added those to most of the trail ends to show you where to go next.

Nice. I found the opening of one trail while I was out there last fall/winter surveying and marked it on my Avenza maps to be able to remember where it is! Thanks pal!
