From Sea to Summit in Snowdonia: Ready to test your mettle in the wilds of Wales?

This one-day challenge is a perfect blend of adventure, natural beauty, and a sense of achievement. Whether you're a solo adventurer or coming with friends, you'll end the day with stories to tell and a new notch on your adventure belt.

Post brief you'll be free to chill the beans ahead of tomorrow's big challenge or trundle into town for a wee explore.

Ain't no backin' out now!

We'll kick things off with a decent breakfast to fuel up for the day then it's off to start this epic challenge.


First up is the 19km cycle leaving the sea at Caernarfon to head for the shores of Llyn Padarn (Llanberis Lake), passing the famous slate mines, rural Welsh farms, and the best scenery this wild country has to offer.

Cycling along the shores of Llyn Padarn, we'll catch our first exciting glimpse of Snowdon looming in the distance.

Once reaching the Snowdon Ranger Path it's time for a quick changeover off the bike and into your trekking get-up, picking up your packed lunch.


You and the gang will then pace it up to the summit having earned an unbeatable view from the highest point in Wales and England. On a clear day, you can see four kingdoms, 24 counties, 29 lakes and 17 islands!

The Ranger Path is a lot quieter than some of the other routes up and passes beautiful lakes before climbing a ridgeline to the summit. There'll be time for victory photos and a breather before we descend the Llanberis path into Llanberis itself.

High on life, it's time for the grand finale - a paddle circuit of the glacial lake of Llyn Padarn - one of the largest natural lakes in Wales.


The final 2.5-mile kayak forms the final push. Emerging from the waters like Poseidon, glory is yours. Challenge completed! Now it's time for a celebratory tipple and lots of questioning to try to find out whose idea this crazy challenge was in the first place.

You'll most likely be pretty pooped after all that so it's a good idea to take a bit of a break before driving.
