Sounds like a job for VRBO or AirBNB.
It wasnt 100% secluded... but check out the places that double diamond ranch has.. just returned from an amazing stay in their aspen room... but they have other cabins (bigger) off main property area not around alot! https://www.doublediamondcabins.com/rentalsEdited: 07 August 2018, 09:38
My family stayed at this cabin just a few minutes from downtown Custer last fall: https://www.vrbo.com/654053. I would not hesitate to stay here again. It is the type of cabin you are looking for - secluded cabin on top of a hill with gorgeous views of the Black Hills. The mile-long gated gravel road to get there passes through National Forest property. The house itself is beautiful and we were a short drive from most of the Black Hills attractions.
Hi, do you remember the name or owner? This listing link no longer works. Thanks!
