Test your limits with the Welsh 3000s Challenge!

The Welsh 3000s is a tough mountain challenge, where you’ll climb the 15 peaks over 3000ft in Wales in under 24hrs! Geographically, these fall within three stunning mountain ranges; The Snowdon Massif, The Glyders and Carneddau.

During the 24hrs of walking, you’ll be ascending and descending approximately 8,000m and walking 50km (30 miles), with a large part of this taking place in darkness and over rough terrain. A very good level of fitness and determination is essential, as this epic route will stretch your physical and mental limits.

We specialise in running our mountain challenges as small group events to ensure a strong camaraderie within the challenge team. Our small instructor to client ratios guarantee you a highly personal experience – our expert guides will know you by name and support you on every step of the journey!

This monumental mountain challenge is not to be underestimated, but the sense of achievement and satisfaction you’ll gain from the adventure is undeniable.

Mountain LeadersYou’ll be guided by an expert instructor who holds a Mountain Leader qualification and has experience of the Welsh 3000s or other endurance mountain challenges. All Hatt Adventures group leaders are wilderness first aid trained and maintain radio communication with the support team during the challenge.

Support Team – Your support team's job is to transport you from peak to peak, as well as provide moral support (not to be underestimated!) and back up mountain safety to the Mountain Leader(s) if required.

Training for the Welsh 3000

We provide a full training package to ensure you are well-prepared for your challenge. This includes a fitness training program put together by our fitness endurance specialists, plus important information on walking boots, clothing, equipment, and the best places to buy them from.

We also run regular Mountain Training Days in various beautiful locations across the UK, which will give you the opportunity to try out your equipment, break in your boots and test your fitness.

Fundraising for Charity

If you are completing the Welsh 3000s challenge to raise money for charity, you’ll need to book your space and pay the standard event fee. With all challenge logistics – including transport from the South East – included, you’ll have more time to focus on raising money for your worthy cause!

Conservation and THE Welsh 3000

Every year, thousands of people attempt this challenge in small unsupported groups or as large organised events. At Hatt Adventures we are very aware of the environmental impact this is having, which is why we run our challenges in a responsible way. We plan our timings to ensure that we are not disturbing the local residents at unsocial hours of the night and we ensure that all our clients are fully briefed on the environmental impact the events can have on the mountains and how to minimise them. We also only run small events, thus reducing our impact on the mountain trails.


Group Price

£4,950 for up to 12 people.

We can cater for larger private groups and can arrange various, transport, catering and accommodation options.

challenge teams

Depending on the size of the event, we may transport your group in multiple minibuses. If this is the case, we will divide you into smaller groups for the duration of the challenge. You will be able to choose your group (depending on your fitness level and mountain walking experience) on the first evening but once in your group, you will not be able to change as the minibuses won’t always be together.

Day 1

Travel to North Wales from Brighton via London collecting participants as we go. This will take most of the day but it's a great chance to get to know the people you'll be completing the challenge with. The evening consists of a mountain safety briefing and then an early night to rest for the challenge ahead.

Day 2

We'll be up early and make our way to the foot of Crib Goch – a knife-edge ridge with almost vertical drops on either side! This leads us to Garnedd Ugain and then onto Mount Snowdon, the largest peak in Wales. From there, our route descends to the bottom of the valley, where we'll meet our support vehicle, have a short break and eat a well-earned lunch. From here it's back uphill as we tackle another series of mountains including the Glyders and Tryfan, which hosts the two distinctive standing stones Adam and Eve – dare you make the jump? At the foot of Tryfan we will have dinner before ascending for the final stretch.

Day 3

The final section will be almost entirely in darkness so plenty of head torch batteries are required. This will make navigation harder but your Mountain Leader will be guiding you along the way. With the challenge over, we will all journey home, tired but fully satisfied having conquered the 15 highest Welsh peaks!
