Climbing the Amphitheatre Buttress on Craig Yr Ysfa is a true classic climb in North Wales. The climb itself offers stunning views, while the return journey via Carnedd Llewelyn adds to the epic experience. Ultimately, it’s an unforgettable adventure that promises to create lasting memories.

Just like our “Climbing Cadair Idris via the Cyfwry Arete: A Multi-Pitch Adventure” guide, this isn’t a technical guide about the climb; rather, it’s a picture guide designed to entice you to embark on this adventure yourself with or without kids in tow. We climbed the Amphitheatre Buttress in August 2021 when my children were 9 and 12 years old. Rock climbing in Snowdonia is always an unforgettable experience, with its stunning landscapes, challenging routes, and rich climbing history.

Once again, we enlisted the services of an amazing climbing guide – Bob Thomas at Contour Outdoor. I highly recommend Bob’s services for any climbing or mountaineering activities in the UK or beyond. Once you’ve experienced the best, it’s hard to settle for anything less.

4. GETTING TO THE START OF THE CLIMB

There are two options to reach the start of the Amphitheatre Buttress climb. One option is to approach it from Cwm Eigiau, while the other is to walk in from the Ogwen Valley. Our guide, Bob, chose the former, and we walked in from Cwm Eigiau. It’s worth noting that the approach from Ogwen Valley entails a very steep descent to reach the start of the climb, so be prepared for a strenuous hike if you opt for this route.

Park your car at the car park located at SH 731 663 at the end of the approach road in Cmw Eigiau.

5. THE WALK-IN

Approach from Cwm Eigiau: From the car park at SH 731 663, head south-west along the path. You’ll come across a stream at SH 723649 after around 1 km. Continue south along the stream. After crossing the stream again at SH 718640, head west on the path, and cross the stream for the final time at SH 701 635 until you reach the final steep ascent of about 300 metres. This leads to the start of the climb at SH 693 637.

The approach took us 1.5 hours and was a good warm-up for what was to come, especially the last 300m of ascent to reach the base of the climb.

After reaching the base of the climb, we all geared up, adjusting our layers to suit the conditions and swapping our hiking boots for climbing shoes.

Personally, I tend to feel hot while hiking but cold while climbing due to the slower pace. Therefore, I usually add an extra layer of clothing before the climb, a wind-proof soft-shell jacket is a great option.

6. The Climb

After getting geared up, it was finally time to start climbing. Throughout the entire climb, the kids and I took turns going first or second, based on our guide’s instructions. I cherished the few quiet minutes, while the kids climbed, and took in the breathtaking views and tranquility of the Welsh hills.

In the following images, you can see the terrain and get a sense of the climb’s difficulty. The climb was pitched at just the right level for us, or rather, for me. The kids have been out-climbing me since the first day we set (hand and) foot on a crag!

The crux of the climb, which refers to the most difficult section of a route, was situated on Pitch 4. The kids did a great job navigating this section, and I somehow managed to make it past it as well.

The pinnacles are the highlight of the Amphitheatre Buttress climb. We traversed the pinnacles as opposed to climbing over them which was still a thrilling experience. My daughter also had the added task of retrieving placed protection gear as she was the last climber on this pitch. She did a great job!

7. The Walk-Out

The walk-out was just as breathtaking as the walk-in with regards to the scenic views.

Initially, we headed towards Carnedd Llewelyn, which is the second-highest peak in Wales, standing at 1,064 metres. From there, we headed north-east to the saddle before descending south-east on a broad ridge. Finally, we continued our descent in a south-easterly direction towards the access road, which took us back to the car park located at Cwm Eigiau.

The terrain consisted of a mixture of clearly defined gravel paths, paths traversing grasslands, as well as sections where we had to walk across grasslands without any designated path, which was strenuous on the ankles.

The views towards Bwlch Eryl Farchog on our way to Carnedd Llewelyn were stunning.

9. Campsites in North Wales

Dolgam Campsite

We stayed at the Dolgam Campsite which is a 45-minute drive to the car park in Cwm Eigiau. It’s a simple campsite with very clean facilities that has a relaxed feel to it. They also offer Bed & Breakfast if camping isn’t for you.

10. FINAL WORDS

We climbed the Amphitheatre Buttress three days after hiking up Ben Nevis in Scotland. During this climb, I was still suffering from muscle ache, which definitely taught me a valuable lesson.

Nonetheless, we had an epic day of climbing, and both my kids did amazingly well. It has become a little family tradition to climb for a couple of days with Contour Outdoor every year. A day out climbing with the kids not only fills my cup, but also my heart, soul, and muscles. There is no one else I’d rather go climbing with than my kids (although it would be cool to climb with Alex Honnold one day, I would still take my kids with me!).

Climbing the Amphitheatre Buttress was our second-ever multi-pitch adventure, and it was amazing! Once again, our guide Bob at Contour Outdoor delivered an unforgettable day by pitching the difficulty at just the right level for us. This is one of the reasons why, when you’ve found the best, you don’t settle for anything less.

Climbing with kids in tow can also be very amusing. Here are a couple of anecdotes from our day: My son commented, “I’ve climbed on nothingness!” after scaling a slab with only a few small holds. And my daughter exclaimed, “Oh my god, I’m gonna get hit by a bush!” upon emerging onto a heather-covered ledge.”

As I highlighted in our “Climbing Cadair Idris via the Cyfwry Arete: A Multi-Pitch Adventure” guide, adventuring solo with kids isn’t about doing it all by yourself. Rather, it’s about initiating it yourself without having to rely on someone else to join you; be it a spouse, partner or friend. So, plan that climbing, canyoning or rafting trip and book a guide! I only recommend guides/providers that we used ourselves and were happy with. Check out Top 20 Family Outdoor Activities in Wales for various activities and recommendations for guides & providers.

Happy Climbing!
