Analysing terrain data
The exposure grade describes the potential consequences of falling or slipping off the path.
Low Exposure: The path is on completely flat land and potential injury is limited to falling over.
Medium Exposure: The trail contains some obstacles such as outcroppings and rock which could cause injury.
High Exposure: Some trail sections have exposed ledges or steep ascents/descents where falling could cause serious injury.
Extreme Exposure: Some trail sections are extremely exposed where falling will almost certainly result in serious injury or death.
"The Aska Trail System has almost a split personality,” writes GregRidesTrails.com.
“The trails on the west side of Aska Road are very steep and reasonably technical.
The other half of the trail system on the east side of the road is still hilly.
.but in general, the climbs are more reasonable and the singletrack is pretty fast and buff.” While a few rocks and roots punctuate the singletrack on the Green Mountain side, overall the fast, flowy trail tread reigns supreme.
In fact, parking at the Long Branch parking lot and simply riding the short Long Branch trail (as oxymoronic as that description may sound) as a loop is possibly the best beginner singletrack mountain bike ride in the Appalachians of North Georgia. If you choose to continue on the Green Mountain Trail, eventually you’ll access stunning views of Lake Blue Ridge.
The route mapped here is shown as a loop, but you’ll need to use roads to complete the northern reaches of the loop.
Should you prefer to maximize your singletrack experience, it’s best to just turn around and pedal back up the mountain. Sources: http://www.gregridestrails.com/2010/10/green-mountain-trail-review-blue-ridge.html
