The Challenge
Stand on the summits of all 16 Welsh peaks over 3,000 ft, traversed in one continuous route across three mountain ranges. A significant step up from the UK National Three Peaks.
Location
Eryri (Snowdonia) National Park, Wales — spans the Snowdon Massif, Glyderau, and Carneddau ranges.
Peaks Summited
Foel-fras 3,090 ft
Carnedd Gwenllian 3,038 ft
Foel Grach 3,202 ft
Carnedd Llewelyn 3,490 ft
Yr Elen 3,156 ft
Carnedd Dafydd 3,425 ft
Pen yr Ole Wen 3,208 ft
Tryfan 3,011 ft
Glyder Fach 3,261 ft
Castell y Gwynt 3,188 ft
Glyder Fawr 3,284 ft
Y Garn 3,106 ft
Elidir Fawr 3,031 ft
Crib Goch 3,028 ft
Garnedd Ugain 3,494 ft
Yr Wyddfa (Snowdon) 3,559 ft
Distance
31.4 miles
Ascent
12,083 ft
Typical Duration
24 hours is the traditional target. Very fit parties/fell runners can complete it in well under 12 hours. Frequently split over 2–3 days for a less extreme itinerary.
Terrain
Rocky paths and technical ridgeline sections. Includes Crib Goch, one of the UK’s most exposed scrambles with significant fall consequences.
Difficulty
Extreme. No support vehicles between peaks (unlike the UK National Three Peaks and Lake District challenges), genuine scrambling ability and a head for heights required.
Best Season
May–September. Crib Goch becomes a genuine winter-mountaineering proposition (ice axe/crampons) outside summer months and should not be attempted by non-technical parties then.
The Experience
This is a mentally, physically and technically tough challenge which requires prior scrambling or exposed-ridge experience.
