Gist Ddu presents an array of ribs and corners embedded in the mountainside above the serene Llyn Lliwbran and is the hiding place of one of Wales' great HVS mountain routes. Conquering the line of Aardvark requires good judgement of the conditions. It is worth noting that the routes feel like a real adventure and require vegetation management skills. Gist Ddu needs a long dry spell to come in to good condition.
