They have 3 loops of trail that are marked with yellow (shortest) red (medium) and orange (longest) blazes on the trees that are easy to follow. Various surfaces will be encountered on the trails, good old dirt as well as sands of the white, gray and yellow varieties. The yellow is the most trustworthy beneath your wheels. The gray is almost always good but can be a bit soft in spots and loose in a corner. The white should be met with some hesitation, it shifts quickly. Riding tip, shift rearward and put more weight on your rear wheel, try and pedal smoothly with even pressure and lighten the front wheel so it floats on top of the sands.
