A wonderful sequence of limestone arches on the NW wall of the Piatra Craiului
, above the spot called La Zaplaz
The following information was kindly supplied by Peterbud (see commments):
Friedrich Deubel, from Braşov (or as he would have said: Kronstadt), was the first (along with two friends) to climb down this way from La Om peak, in August 1886. A year later he marked the route (later referred to as "Deubel's route") with red signs. In 1904 the SKV (Siebenbürgische Karpaten Verein) fixed chains along the most difficult sections. Hence the route is also referred to as "La lanţuri" (the chains)
Also, SP offers views of the other side of Deubel Holes.
