The trails are broken up into three colors. White, Blue and Red. The white is for intermediates, the blue for advanced and the red for expert. I took the blue and mixed it with some red and all I can say is be prepared for an intense ride. You will get a work out. Plenty of shade and creek crossings. I would recommend doing this ride in the early morning. There is a cost for using this however. The price is $10.00. The price covers all day use and parking. The owner of the ranch is amazing and friendly. Since this is a horse ranch the horse riders have the right of way, but since there are so many trail systems there is not much to worry about.
