I agonised over whether to post this site or not, but then I saw the Kirkstone in Cumbria and decided to after all. 915 metres up in the air, Tryfan is a tall sharp mountain. It really scared me twice, but I got up in the end. Adam and Eve are two natural standing stones on the 25ft sq summit platform. If your man(crazy) enough to jump from one to the other, then the freedom of the mountain is yours. There was no chance of chickening out because there's just no way I'm going up there.. right on the edge with a very very big drop! In short, it's a long but exciting climb, with added bonus of the initial stimulus for standing stones... honest!
It might be related to the stones, it might not. It doesn't seem unreasonable to think it would be, as many similar places have grave-related folklore. This is a line from 'Stanzas of the Grave', a 10th-century Welsh poem:
"the grave of Bedwyr is on Tryfan hill."
Bedwyr is one of King Arthur's mates and one of several Arthurian characters mentioned in the early poem. You can read the rest of the poem at this page at the University of British Columbia: http://faculty.arts.ubc.ca/sechard/344art.htm
Heard from the Mountain Rescue guys that a number of people have had 'mishaps' trying to gain the freedom of Tryfan. There's a moral in there somewhere.
Postman's spot on - I'd have thought making it to the summit with those two quite frankly bizzare monoliths is freedom enough without endulging in such macho bull...
Don't have anything to match Postman's superb summit shots so just posted a couple of general pics of this incredible sacred mountain.
