The row is set against plans to site a 9-metre solar powered stairlift up to Hay Tor Rocks, one of the National Park's most popular tors.
The scheme has just been submitted for planning by architect Nick Childs and artist Alex Murdin.
These designs also include a 500m 'zig-zag' path made from granite climbing up to the tor. The ambition of both elements is to allow disabled people to access the site, which is visited by thousands of able-bodied tourists every year.
But the plans have not met widespread support from local conservation groups.
President of the Dartmoor Preservation Association, Kate Ashbrook, said the plan was 'just bonkers' and what was being proposed was a 'hideous eyesore'.
