Insidious MD is vicious, body armor savagery that is the most advanced trail in the Greer Ranch System. See how they all fit together on our EnterActive Map. It is accessed from the climb toward Distortion Trail. At the last intersection before the ridge, continue straight to go to the Revolution Trail which drops off the backside and then Insidious shortly after that. There is a new section at the bottom of Insidious that adds to the savagery.
