Take on this Snowdon challenge, from Castle to Castle, and learn more about Snowdonia's rich history along the way

After meeting your Mountain Leaders in Llanberis, we'll transport you by coach to Caernarfon Castle. Standing at the mouth of the Seiont river this 700 year old castle is the official starting point for your Sea to Summit challenge. The first half of your journey will be through the lowlands surrounding Caernarfon taking in the Welsh Highland Railway and the Snowdonia Slate Trail. Upon reaching the Snowdon massif, you'll cross over the ridge line into the Llanberis valley before your climb begins in earnest. Heading up to Bwlch Maesgwm, the Ranger path will then lead you all the way to the summit. The last part of your journey, will be down the Llanberis path into the village before a quick detour to 12th century Dolbadarn Castle for a final team photo.
