Twll Mawr’s West Wall is best known for the Dawes classic ‘The Quarryman’ and boasts a good number of desperate and unrepeated slate masterpieces. ‘The Wonderful World of Walt Disney’ is one of these. It very rarely gets climbed perhaps being overshadowed by its more famous neighbour and has four fantastic and varied pitches. A slippery layback groove, a technical arête, an outrageous jump across a groove and a delightful finishing slab. It’s graded at E6 6b or a spicy F7b. Get on it!
