There is no park trail to reach Devils Den. We were on Ramsey Cascades Trail for about two minutes before heading off trail up the ridge. You could drop down from a Jeep trail that goes to the fire tower remains on Greenbrier Pinnacle as well. We eventially bushwhacked up to the Jeep trail (unmaintained) and to the tower. We came back down the Catstairs to some home places and the Barnes Cemetery.
