Shadowcliff - Grand Lake, Colorado
The Shadowcliff story begins with a tent and a campsite on the banks of the North Inlet stream. In 1956, Patt and Warren Rempel dreamed of building a simple, rustic lodge and purchased two lots on the North Inlet stream in order to fulfill this dream. Inspirational morning meditations on a promontory, which overlooked Grand Lake and Shadow Mountain Lake, served as the source of the dream which became Shadowcliff. After several summers of tent living by the stream the Rempels purchased the remainder of the land and began the first building project in 1959. By 1981, construction of the main buildings was completed through the efforts of approximately 650 volunteers from 45 countries. This volunteer tradition continues as more than 100 volunteers participate each year in a variety of ways including work projects throughout the month of May (pre season opening) and throughout the regular season.
