Welcome to Llechwedd Slate Caverns, the most popular visitor attraction in North Wales! Llechwedd Slate Caverns are situated on the A470 between Blaenau Ffestiniog & Dolwyddelan. We are only 3/4mile from Blaenau. Boarding a train in a corner of the original slate slabbing mill of 1852, visitors now ride into an 1846 tunnel, hauled by battery-electric locomotive. Entering through the side of the mountain this journey into the early Victorian past remains on the level, and traverses some spectacular caverns. Passengers alight at various points to learn something of the strange skills needed to extract the slate - conveniently bedded between layers of granite-like chert, which gave integral strength and roofs for the mine's 16 floors, aligned through a vertical distance of 1,000ft (305m) underground. There is a sound and light tableaux deep underground and guides describe other chambers. Visitors descend on Britain's steepest passenger railway, with a gradient of 1. This place can create the most unique and unusual event, it offer wedding services, conferences&meetings and general celebrations services and facilities.....
