Starting in the upper reaches of 5 Mile near the trailhead for Tinfoil Hat Downhill
and Andreas' Downhill
, this southbound trail traverses a very nice bench land with several small creek crossings and some lovely mixed forests. The trail ends at the Packsaddle Creek parking area. If ridden in reverse (from the Packsaddle Creek parking area), the Selwyn Traverse becomes a long, continuous uphill; the grade is never severe but the uphill climb is unrelenting.
