Snowdonia Challenge

Snowdonia’s unique hiking challenge
3 days – 100km

24 – 26 June 2022



Snowdonia Challenge weekend each year sees individuals and teams of walkers from all over the UK (and further afield) challenge their mental, physical and emotional resilience in the beautiful surroundings of Snowdonia National Park.

Three days, three stunning but challenging routes and some of the best views Snowdonia has to offer. 

Snowdonia Challenge routes take you away from the busiest areas of the national park. All routes are signed (no need to navigate) and you’re fully supported along the way.

Not for the faint hearted this challenge will take you on a journey of self discovery. It is inspired by multi-day challenges used as military training events in Europe.

Snowdonia Challenge is based in Betws-y-Coed, North Wales. The perfect base to explore some of the less visited parts of Snowdonia with some of the best views the national park has to offer.

Come as a team or on your own and chose 1, 2 or the full 3 days either as a fundraising challenge or just for fun. 

Taking part in Snowdonia Challenge you will be part of an amazing experience where you will make new friends and explore parts of Snowdonia you’ve never been before.

The first Snowdonia Challenge was held in 2017. Created by Breese Adventures and inspired by an event in Holland which started in 1909 as a  military training event and now attracts 46,000 military and civilian participants each year.

“I took part in Nijmegen Marches in 2009 and it was life changing. It took me on an incredible journey self discovery and proved to me what commitment and determination could achieve. I’m positive by taking part in Snowdonia Challenge you will experience the same range of emotions and feelings of personal achievement that I gained in 2009. I very much look forward to seeing you there and sharing this adventure with you.”

Tracey – Breese Adventures co founder and creator of Snowdonia Challenge

Day 1 – Gwydyr Forest and Llyn Elsi

Distance 38km

Height gain 1530m

Rest Stop 1 at 12km (Water, snacks & toilets)

Rest Stop 2 at 26km (Water, snacks & toilets)

Day 1 takes us out south of Betws-y-Coed through Gwydyr forest to the stunning Llyn Elsi reservoir with panoramic views across to the Moelwynion and Carneddau.

From here we descend into our first rest stop Pas Penaeldroch Café, via the Sarn Helen roman road (260km/160m which follows a meandering course through central Wales, connecting Aberconwy in the north with Carmarthen in the west).

Once through rest stop one, we continue along by the Afon Lledr to the quite village of Dolwyddelan before heading up through Gwydyr forest, below the imposing Moel Siabod mountain.

The route now heads along open moorland towards Capel Curig before switching back on the old roman road passing Caer Llugwy Roman Fort.

The second rest stop will be a welcome sight, with an opportunity to stock up on water and snacks before heading back up into Gwydyr forest above Betws-y-Coed.

The final section of the day takes us close to Llyn Elsi again but this time we pick up the Jubilee path with stunning views across the Conwy Valley for our final descent back into Betws-y-Coed and the finish of day 1.



Distance 33km

Height gain 900m

Rest stop 1 at 13km (Water, snacks & toilets)

Rest stop 2 at 18km (Water & snacks)

Day 2 takes us west out of Betws-y-Coed through Gwydyr forest above the Afon Llugwy until we reach the Tynllwyn Viewpoint which looks back down the Llugwy valley towards Betws-y-Coed.

The route now continues towards Capel Curig and as we come out of Gwydyr forest we have stunning panoramic views of the Snowdon Horseshoe, Moel Siabod and the Carneddau mountain range. The views on a clear day are simply breathtaking.

From here we descend into our first rest stop of the day at the legendary Moel Siabod Café, in our opinion the best café in North Wales. We highly recommend that you stop and sample the amazing homemade Siabod cakes!

Once through rest stop one, we continue along the Nant-y-Benglog valley with stunning views of Tryfan and the Carneddau, now heading towards rest stop two at Gwern Gof Isaf campsite.

Take time here to realise the shear scale of the U-shaped valley that you are standing which was formed by a glacier in the last ice age some 10,000 years ago.

We reverse on ourselves for 4km before heading off towards Llynnau Mymbyr with panoramic views of Snowdon Horseshoe from Capel Curig. A definite photo opportunity from the bridge on the lake.

The going from here is easy now as we head back via the old roman road and alongside the Afon Llugwy into Betws-y-Coed and the finish of day 2.


Day 3 – Day of the Lakes

Distance 29km

Height Gain 1185m

Rest stop 1 at 9km (Water, snacks & toilets)

Rest stop 2 at 20km (Water & snacks)

Day 3 takes us north out of Betws-y-Coed through Gwydyr forest and up towards Cors Bodgynydd Nature Reserve heading towards our first lake Llyn Geirionydd.

Llyn Geirionydd which lies in the valley where the northern edge of the Gwydyr Forest meets the lower slopes of the Carneddau mountains and is the location of our first rest stop. It is a beautiful 1-mile long lake and covers an area of 45 acres (180,000 m2), but is never any deeper than 50 ft (15 m).

From here the route takes you around the lake and over into Gwydyr forest before descending to our second lake of the day, Llyn Crafnant. The Forest Park guide (2002) once stated that “the (view along Llyn Crafnant) is one of the most breathtaking views in all Snowdonia so be sure to take lots of photographs.

The route continues heading down towards the village of Trefirw and our second rest stop at Roualeyn Fuchsia Nursery.

Be sure to take plenty of water and snacks on board as the next section rises steeply above Trefriw back into Gwydyr forest heading towards our final lake of the day Lyn-y-Parc reservoir.

The final section of day 3 and the whole Snowdonia Challenges sees us heading down through the forestry into Betws-y-Coed for celebrations and deserved congratulations!

This challenge is suitable for anyone over 18 who is confident of their fitness levels or ready to commit to training over the next few weeks and months.

  • "The best 100k we've ever done" - Snowdonia Challenge 2017

  • All members of the team we met were very helpful and encouraging. This has been one of the most organised events I have taken part in, you seem to have got it almost right 1st time, well done.

  • This was such a fantastic event, tough enough to be a challenge for mere mortals, yet achievable to anyone with the determination to train and push themselves. It was also an emotional journey that will stay with me for a long time.

  • The challenge was so phenomenally well organised and you, Tracey and your whole team were absolutely brilliant. See you all next year!

  • Well done guys on a very successful Snowdonia Challenge 2017. Thoroughly enjoyed the whole weekend and cannot begin to thank you enough for such a well organised event. Every last detail was thought of and every person who formed part of the organisation for the weekend was knowledgeable, approachable and motivating! We met some fantastic people and made amazing memories. Thank you Tracey, Stiwart and team very very much. We wish you every success!!
