Snowdonia National Park provides the stage for the ultimate UK mountain challenge, where the mightiest peaks scrape ever-changing skies. With such a formidable mountain shield you will conquer 15 mountains and ascend over 4000 metres as you climb all 15 peaks over 3000 feet in Wales in just 3 days. Your mountain adventure includes summiting Snowdon, the highest peak in Wales at 1,085m, whilst also crossing the Carneddau, Glyders and Snowdon ranges, ascending ridges and linking peaks in rapid succession. Highlights (and bragging rights) include the two standing stones thought to date from the Bronze Age, crossing Y Glyderau which is one of the most impressive mountain ranges in Britain, scrambling up Tyfan at 917metres with its classic pointed shape with rugged crags, climbing onto the precariously positioned Cantilever rock for a classic Snowdonia photo and crossing the top of Twll Du (Devils Kitchen), following in the footsteps of Charles Darwin. Devils kitchen is known as the Nature’s Hanging Gardens because of its rare Alpine plants and if you’re lucky you may even find the Snowdon Lily, one of our most endangered plants.
This mountain adventure culminates on your final day with the possibility of scrambling along one of the greatest ridge walks in the UK, Crib Coch. If you love the mountains, then this mountain experience is one that you don’t want to miss.

Our Welsh 15 Peaks challenge’s are run with experienced local mountain leaders who love this 3 day journey through the mountains. So while en-route you can pick up a few new skills such as map reading and taking a compass bearing plus find out more about the local history and flora and fauna while enjoying the best Snowdonia has to offer.

Essential Information

Weather & Safety

The weather in the mountains can change very quickly, what can start out as a good day can soon become very poor. It is very important to be well equipped and prepared for all conditions.   We will be crossing terrain varying from moorland to lose rocky ground. Our route will be ascending and descending a great deal and therefore a good level of fitness is required. The Leader reserves the right to change the itinerary at any time should the conditions require it.In these circumstances we will make the best alternative arrangements possible that maintain the integrity of the original itinerary. All our guides are first aid trained and carry fully equipped medical kits for serious medical emergencies.

Level of Difficulty

The Welsh 15 Peaks is a tough challenge given there are consecutive long days of trekking over some tough terrain. The trek requires a good level of good stamina, fitness and a determined attitude. The weather and/or basic living conditions will also add to the challenge. Taking part is all about achieving YOUR personal ambitions.

It’s not just about getting up and down the mountains! There are other aspects to the trip which you may find challenging: no toilet facilities on the mountains, washing facilities that you are not used to; being away from your family for consecutive days; or simply being with a group for multiple days with little privacy.

If you find it tough, chances are someone else will be struggling too. You’re all in it together and encouraging each other creates a supportive group atmosphere – and some of the best memories! Plus, everything you find hard adds to your achievement and your memories.

The weather can have a huge impact as well. Although we choose departure dates carefully to maximise the chance of good weather, there is always the possibility of rain, strong winds and extremes of temperature in North Wales, especially in the mountains.

Good kit can make a real difference to your personal safety in extreme weather. We provide you with a detailed kit list and are always on hand to advise you. It doesn’t need to be expensive, but you do need to be well-prepared.

How fit do I need to be?

Training and a good level of mountain walking fitness is definitely required, this is a tough challenge and with some sections of exposure. As much preparation and training you put in beforehand the better chance of success you have and the more enjoyable the trekking will be. You will be walking an average of 8 – 10 hours per day for three consecutive days.


On arrival in Snowdonia we will be staying in hostel accommodation. Upgrade grades to either Bed & Breakfast or Hotel is available on request.

What are the group sizes?

Our maximum size group is 12 per Mountain Leader, with a minimum of 6 per group.

Who will be leading the group?

We employ experienced and fully qualified Mountain Leaders to accompany and lead you. All our Adventurous Ewe Guides are qualified Mountain Leaders and have been carefully selected to ensure you have the best experience on your trek with a bit of humour thrown in for good measure. Your Leader/s are mountain first aid trained and have extensive experience in leading the Welsh 15 Peaks Challenge.  They will be ultimately responsible for your safety on the mountain. They will be carrying full safety equipment and a mountain first aid kit.

What do you do to protect the environment?

We limit the impact we have on the surrounding environment by remaining on the paths at all times so as not to cause further erosion on the mountain. We will ensure that all rubbish is disposed of responsibly and take all rubbish away with us. We operate by a ‘leave no trace ethos’. We also make a contribution to the fantastic environmental charity, Cool Earth, through our partnership with them.
