“A quick climb up the two hills (the Sisters) on the southwest edge of Mountain's Edge.
— Rob Erekson
Twin Sisters starts off of Road to Ridges Connector
and quickly becomes a steadily climbing singletrack to the top of the first of the Sisters. Once at the top, head down the north slope between the two hills and to the top of the second. Once there, you can return the way you came or continue down the northwest slope along Quick Exit to the waterfall and wash that links back up near the beginning of the trail.
