Overview

A magnificent challenge – setting out from Penrice Castle basecamp with a range of camping options. It’s a figure-of-eight route – heading on a clockwise west loop first, heading down to Oxwich Bay and joining the stunning Wales Coast Path. You’ll be stopping every 12.5km for refreshments and whatever support you need – then you head inland, join the elevated Gower Way, with a main halfway stop back at Penrice Castle basecamp. Another 50km on the east loop – along the coast past Mumbles Head, inland up to Gowerton – and then a final push back to basecamp where a massive welcome awaits!
