Welsh 3000s Challenge | 3 Day - Snowdonia 15 peaks Challenge | North Wales

Course Info

The Welsh 3000s is one of the finest mountain routes in the UK summiting all 15 of the highest peaks in Eryri / Snowdonia - either as a single 24-hour push or over multiple days.

Our three-day Welsh 3000s Challenge allows you to undertake this incredible mountain route over a more enjoyable three-day itinerary where we provide everything from transport and accommodation to guides and valley support.

Our Welsh 3000s Three-Day Trek offers a more enjoyable and rewarding way to complete one of the UK's most iconic mountain challenges. Rather than tackling all 15 peaks and 14 miles of rugged terrain in a single demanding push, we split the route across three days, allowing you to fully enjoy the spectacular landscapes of Eryri (Snowdonia) while developing your confidence in the mountains.

Over the course of the trek, we explore each of the three great mountain ranges in turn: the Snowdon Range, the dramatic Glyderau, and the expansive Carneddau. By dedicating a day to each range, there is more time to appreciate the incredible scenery, take in the unique character of each mountain group, and enjoy the journey rather than simply focusing on completing the challenge.

Spreading the Welsh 3000s over three days also gives us much greater flexibility when it comes to mountain weather. Our experienced guides can adjust the order of the ranges to make the most of the conditions, helping to maximise your enjoyment and increase the chances of experiencing the mountains at their best. Whether you're looking to complete the famous Welsh 3000s challenge or simply enjoy three fantastic days of mountain walking, this format provides a safer, more enjoyable, and far less rushed experience than attempting it all in a single day.

Every day is around 10 miles with approx 1400m of ascent. You will need some prior hill walking experience and be able to walk for three days. Because this event involves scrambling you will need some prior grade 1 experience. 

Once you arrive at the hostel we take care of all the logistics. We provide the guides, accommodation and ensure you get transported around to the start and finish every day. We don't provide food or drinks as these are very specific to the individual. 

Refreshments will be provided at the end of every day including some fantastic locally made cakes. 

With a number of leaders available and logistical support in the valley we ensure you are totally looked after every step of the way. Should you be unable to continue a guide will bring you down to the nearest road junction to be transported back to your accommodation. 

Testimonials

I've now been on two courses with The Mountaineering company. Both courses were great, learnt loads and Matt/Sam were brilliant instructors. I would definitely recommend to anyone getting into mountaineering to book onto intro and development courses. I'm looking forward to doing more courses with them in the future. (Google Review)

Alex Heaps

My partner and I booked Matt for two days mountaineering instruction so we could learn how to use ropes on climbs that were out of our comfort zone. We had a fantastic two days and Matts structured approach allowed us to take it all in and practice all the techniques over and over again. We both now feel more confident to take on more adventurous scrambles. Thanks Matt

Andy and karren

Fantastic day on the Back to Basics Navigation course with Matt. Very well organised and learnt a lot. Matt was very professional and great at teaching the skills with lots of patience and encouragement. Really enjoyed it and will definitely be signing up to other courses in future. Highly recommended.

Chontelle Wright

A great day out learning how to use a map and compass with Matt. His teaching style gave us just the right amount of information without feeling overloaded. I would highly recommend Matt !

Chris

Just got back from a fantastic weekend with Matt on the Welsh 3k and couldn't have asked for a better time. We had blue skies and cool air so it wasn't too hot and the views were simply incredible. Matt set a great pace allowing us to push our limits but never going beyond what we were capable of and we finished in 18 hours 32 mins. Hes a top bloke and I would certainly recommend him and The Mountaineering Company to anybody. Thanks again Matt. You will certainly see us again next year no doubt!

Chris Mansell

We attended a navigation course today with Matt. He was fantastic, can’t rate him highly enough! We had no knowledge at all, but have come home feeling confident and ready to tackle our adventure! Thank you Matt for a fabulous, fun day

Claire Black

I thoroughly recommend Matt as a leader & guide. I experienced an exhilarating & fun day with a super group doing Matt's Ogwen Classics day. Matt managed our mixed levels of ability & confidence with a calm, encouraging, alert & purposeful manner. He inspired confidence through recognition of our efforts & shared his knowledge & experience to support our skill development. The day passed all too quickly!

Recently attended an intermediate rock skills course in the Peak District. Really great weekend and excellent fun. Matt is a top bloke; very knowledgeable and just the right amount of laid back. Allows all the information to really sink in - effective teaching!

Excellent day out with Matt on my first ever Scramble. I found it pretty tough in places but Matt was always there to put me at ease, offer instruction and with his support I made it to the top. Would highly recommend to others.
