Snowdon Horseshoe via Crib Goch, Garnedd Ugain, Snowdon and descent via Y Lliwedd or option to continue to Nantgwynant and take either car or bus back to Pen Y Pass. Would depend on linear walk arrangements and cars.
Main challenge is exposure on either side of the Goch. Subject to weather, this requires a good head for heights and firm footing, all fours, if necessary.
The pay off though, again weather dependent, is the views, the thrill and the sense of accomplishment.
People intending to take part in this event should read GOC's document Safety in the Hills.
