Each Summer Term, after A2s have finished,  a group of Upper Sixth Formers attempt this famous traverse of the 15 peaks over 3000 feet in Snowdonia, North Wales. It is a demanding expedition of 30 miles, with 12,000 feet of ascent. The challenge is to complete it in one continuous walk within 24 hours.

 

 

 

The route is over rocky terrain, but it does not involve climbing. The views are spectacular and the ground much more rugged than either the Black Mountains or Mid-Wales.
