Expect around 50km on foot, close to 4,000m ascent, exposed Grade 1 scrambling, rough descents, long climbs, and serious fatigue by the final range. This is not just a long walk. It is one of the biggest mountain challenges in Wales. WHY MOUNTAIN CRAFT? The value of being guided is pacing, judgement, route choice, and knowing where the day is most likely to unravel: Crib Goch, the Nant Peris descent, the Glyderau line, Tryfan, Pen yr Ole Wen, and the final Carneddau section. My own Welsh 3000s summit-to-summit best is 11 hours 39 minutes, moving north to south and including the North Ridge of Tryfan and the North Ridge of Crib Goch. On guided events, the aim is a strong, steady, well-managed attempt with clear decisions throughout. Mountain Craft now has 50 five-star Google reviews across guided mountain days, scrambling, Crib Goch, Tryfan, Welsh 3000s and private guiding. WHAT’S INCLUDED 2 Mountain Craft leaders on the hill Support vehicle and driver at key valley points Drop bags Water refills Hot water, tea and coffee Food resupply Extra layers at checkpoints Headtorch or battery swaps Basic first aid and withdrawal support if needed Pre-event kit, logistics and preparation information Weather-aware route decisions throughout You still need to carry the right kit and look after yourself between checkpoints, but you do not have to manage the whole challenge alone. WHO THIS IS FOR You need strong hill fitness, previous long mountain days, a steady head for exposure, and ideally previous Grade 1 scrambling or Crib Goch experience. For people who want a serious attempt with clear leadership, small-team pacing and proper support.

The route, timing and plan may be adapted if weather, conditions or group safety require it.
