Savannah Loop is located off of the Front Country trailhead at GCSNA. It is mainly singletrack with a stretch of jeep path. There are creek crossings along the trail which are the hardest of the rock gardens.
Unlike the other trails located on GCSNA, the rock gardens on Savannah Loop are very tame. You should worry more about the roots than the rocks on this ride. This trail also intersects Lytle's Loop
in two locations. This one allows you to make a longer, more peaceful, ride if you are only a beginner.
