Green World begins directly off of the Zephyr Lift and is the easiest way down the mountain from this point. The trail plays host to wide, buffed out singletrack that beckons more experienced riders to open up the throttle.

The first feature Green World presents is an incredibly easy wooden rollover which leads into some wooded, fast-flowing singletrack. The trail then pops you out onto an open ski trail at an intersection with Rainmaker. Beware of other riders here as the two trails do merge.

Stay left when Green World and Rainmaker diverge and enjoy the scenery as the trail winds back and forth. Be sure to keep your speed in check however, as the technicality of this trail is solely determined by the speed you carry through the buffed out, bermed turns. Shortly after the meeting with Rainmaker, Green World dives back into the woods and pops out intermittently onto ski trails with beautiful vistas.

After a few of these vistas, you'll enter the trees again and cross over an incredibly beautiful, lush area with a wooden stream crossing. This would be an ideal area for a break and a quick snack. Continuing through the trees, Green World then comes to an intersection with Lonesome Whistle, one of the mountain's XC trails.

Follow the trail's fast contours through the woods and across an open ski slope. You can easily build a lot of speed here. Shortly thereafter, the trail tilts upwards and begins climbing. This climb brings the trail directly parallel to Free Speech.

Green World and Free Speech parallel for a while, during which time riders encounter less than buffed out terrain. The trail has some slight drops that are easily ridden and some very small rocks scattered throughout. Eventually, you'll arrive at an intersection with Arapahoe - stay right. Shortly after this intersection, you'll enter another, featuring Lower Long Trail and No Quarter. Stay left and you'll pop back into the woods.

Enjoy the incredibly flowy and fast singletrack which bring you to two very well built bermed turns. These turns then lead into three, very easy root drops. Continue over some incredibly fun rollers which can be jumped, then it's bermed turns to the finish! Be sure to stop at the vista near the end of this trail for a break or lunch. The views don't get much better than this!

Nice views, some narrow parts through the trees but a good way to start learning switchbacks going downhill
