I have ridden these trails for over 10 years. Easy to follow for most. I frequent the red that goes down into cool bottoms area, and yellow that runs through Pine grove that gorgeous. Have went out north past 2650 on Orange and come back on blue, all marked fairly well. Cell tower twins easy to spot a great market. Some recent bulldozing has affected few areas but very remote feeling, loads of wildlife. Cons: No water/showers. Personally I ride gaited 12-15mls, so the runoff berms are a nuisance after about 40 of them...hard to find long stretch to stay locked onto a gear. 4stars
