Itinerary

Day 1 – Arrival

• We meet in the late afternoon at our hotel accommodation in Caernarfon. We’ll meet the team and have a detailed trip briefing to prepare us for tomorrow’s challenge. Then you’re free to arrange your own dinner, either in the hotel or in town, and get to know your fellow adventurers before a good night’s sleep sets you up the big challenge day! Night hotel. Dinner not included.

 

Day 2 – Challenge day (Cycle approx 10 miles / 16km (1-1.5 hours) / Trek approx 9 miles (4-6 hours) / Kayak approx 2-2.5 miles (1-2 hours)

• After an early start and an energising breakfast, we familiarise ourselves with our bikes, and have a final safety briefing before jumping in the saddle to start the challenge. This first section takes us from the picturesque coastline, past historic Caernarfon Castle and through rolling Welsh countryside, passing quaint villages with the peak of Snowdon looming in the distance. It’s a stunning route (approx 10 mile / 16km), much of it on traffic-free cycle path, as we wind our way through the back door into Snowdonia National Park.
• Arriving at the base of the mountain, we swap bikes for boots, collect our lunch, and begin our ascent of Yr Wyddfa (Snowdon), the highest peak in England & Wales. We ascend via one of the quieter routes, the Snowdon Ranger Path on the west side of the mountain, which carves its way through picturesque farmlands, past beautiful lakes and then follows the ridgeline all the way to the summit (1085m). On reaching the peak, there’s time to soak up the views and take some photos before descending to the northwest, to finish in Llanberis, on the southern banks of Llyn Padarn.
• The grand finale of the day will see you paddling a large circuit of this beautiful mountain lake on 2-man sit-on kayaks, before smashing through the finish line and celebrating with a glass of bubbly with your fellow challengers! We then transfer back to our start-point at Caernarfon for onward travel.
