On the summit plateau of the Rahnfels there is an observation point, the Frankenthaler Hut. This simple, wooden
refuge hut was erected in 1906 by the
Frankenthal branch of the
Palatine Forest Club and offers shelter to hikers in inclement weather. During the
Cold War there was a
US Forces radio relay site and a telephone call forwarding facility for the
DSN network on the southern side of the summit. The tarmac road to the summit dates to this period and ends today at an enclosed and privately owned forest clearing in which the ruins of the military installation are still recognisable. == Transport ==
