The Narrows

About The Area

While officially named Nockamixon Cliffs Natural Area,  it is known to ice climbers as The Narrows. Located near Kintnersville,  it is one of the rare spots in South Eastern PA for ice climbing. These 300+ foot high Brunswick Shale cliffs are encased in ice when the condition are right making for some prime ice routes.

  • This area is NOT open for rock climbing or dry tooling due to the presence of the artic wildflower Roseroot. DCNR allows ice climbing for two reasons. First, once the ice is formed the Roseroot and other species are considered protected under the ice. Second, once the ice melts all evidence of human activity is gone along with it so it is as if we were never even there.


  • The a large portion of the area is CLOSED for ice climbing as of February 1 each year in cooperation with DCNR and PGC due to a raptor nesting site. Please see closure map below. The Access Fund is aware of the closure and has tried in the past to work with state officials.  The best thing climbers can do is comply with the closure as we try to make further progress.
