3 Peak Challenge: Hiking Mount Snowdon (& more of Wales)

A humorous Brit (I’m assuming) came up with the idea to climb the three highest mountains in the UK within 24 hours – dubbed the “Three Peaks Challenge.” Naturally, as a nature lover and gym fanatic, I thought, why not?

Well, it turns out, plenty of reasons! One being not wanting to trek at night. So instead I opted to tackle each peak on separate trips, and convinced some family members to join! Here’s my experience of hiking Mount Snowdon (which at 1,085 m / 3,559 ft is the smallest of the Three Peaks), and exploring the wider beauty of Snowdonia National Park where it’s located.

(And for those brave souls still considering the 24-hour version, there’s a suggested itinerary waiting for you at the end.)

Day 1

Morning:

Exploring Llanberis

We based ourselves in Llanberis, staying in a lovely Airbnb just a short walk from Mount Snowdon. This is a great location, right in the heart of everything. Before tackling the climb, we decided to explore.

We started at the twin lakes, Llyn Padarn & Llyn Peris, which stretch dramatically between the mountains. Wandering along the banks of Llyn Padarn in the morning mist, we passed kayakers and stopped every few metres for “just one more photo.” There’s a stillness to the place – peaceful, quiet, and a world away from everyday life.

Dolbadarn Castle

From there, we took a short walk to Dolbadarn Castle, nestled at the foot of Snowdon. This charming, quaint castle features a climbable tower, and from the top, we were rewarded with breathtaking views of the valley below. I couldn’t help but half-expect a Welsh dragon to appear!

Afternoon: 

National Slate Museum & Llanberis Lake Railway

We then walked through some beautiful greenery, on our way to the museum. Housed in an old slate workshop, the Slate Museum showcases Wales’ industrial history. It was interesting to gain insights into the region’s slate heritage. Afterwards, it’s possible to enjoy a relaxing train ride around the lake – just be sure to check the schedule, as the train runs at set times.

Late Afternoon:

Caernarfon Castle:

We drove 20 minutes to Caernarfon, where the well-preserved castle offered stunning views from the towers, watching the tide roll in. The town’s seaside charm made for a perfect harbour-side dinner. By the end of the day, we were fully relaxed and ready for the summit…

Day 2

Hiking Mount Snowdon (Yr Wyddfa)

By 8.30am we were at the base of the “Llanberis Path” route of tackling Mount Snowdon, which was a short walk from our airbnb. Just to ensure we were at the right place, in true me fashion, I asked a group of women that were descending, “Is this the easy route?” To which, they chuckled! It soon became clear why.

While it has the most gradual ascent, the Llanberis Path is the longest of all possible routes up the mountain; and is likely more about perseverance than technical skill. The first stretch was very steep, but thankfully, after a few minutes, it levelled out.

We soon came across a group of friends, who we initially overtook – briefly fuelling my competitive streak. But the lead didn’t last long; they eventually passed us again! Later on, one of their group began to struggle and ultimately made the tough decision to turn back. He didn’t reach the summit that day, but the determination on his face said it all. It made me think: maybe the climb isn’t about the summit at all – but about what rises in you as you go.

At the halfway point, we saw a train pass by. Yes, there’s a train to the summit if you prefer to skip the uphill grind. But I must say, there’s something meditative about walking the trail. Three-quarters of the way up, we asked some descending hikers, “Are we nearly there?” They replied with: “Nowhere near!” … Well, at least they were honest!

Eventually reaching the summit was a huge moment. Standing at the highest point in Wales, after pushing yourself to get there, really hits. The panoramic views were breathtaking. It was in that moment I knew I had the hiking bug.

Day 3

Zip World & Gwrych Castle

After the intensity of Snowdon, this day was all about fun at a slower pace. However, somehow we found ourselves at Zip World Betws-y-Coed! I opted for the roller coaster – a thrilling ride through the forest. If you’re brave enough to take on the world’s fastest zip line you can do this at Zip World Penrhyn Quarry.

Later, we visited the Gwrych Castle Estate, a former filming location for “I’m a Celebrity Get Me Out of Here!“. The drive up to it is stunning, and the castle’s medieval charm made for a peaceful exploration. While some rooms provide historical info and a section dedicated to the TV show, it’s mainly a spot to wander and enjoy the views and its lovely garden. The castle is owned by a charity who welcome donations for its preservation.

Final Thoughts

Wales exceeded all expectations – it’s breathtaking, picturesque, and has such a calming atmosphere. Next up is England’s Scafell Pike, followed by Scotland’s Ben Nevis for the grand finale! But for now, I’m taking a well-deserved rest.

Some of my hiking tips:

1. Download a map: Here is the [Snowdon Walks app (Llwybrau’r Wyddfa)], the official GPS route. If there aren’t many people on the mountain, it’s possible to get lost on where to go next.
2. Footwear matters: Best not to turn up in basic trainers otherwise you could be slipping everywhere! Proper hiking shoes are essential – your ankles will thank you.
3. Layers, layers, layers: The weather changes quickly on mountains. It can be sunny at the bottom and freezing at the top. We had warm weather when we hiked, so layers were key.
4. Waterproof Jacket: Because, well, it’s Wales. Always be prepared for rain!
5. Snacks and water: Trust me, halfway up, you’ll wish you packed more.
6. Pace yourself: It’s not a race (unless you’re doing the full 3 Peaks in 24 hours, in which case – good luck and godspeed).
