Padarn is one of the largest natural lakes in Wales — ninety-seven hectares of moraine-dammed glacial water below the Llanberis Pass, twenty-nine metres at its deepest. Wild brown trout in the margins; torgoch — Arctic char — in the deep water, where they've held since the last glaciation. A boat helps. The view down the lake with Snowdon behind is the kind that justifies a long drive even on a day the fishing doesn't quite happen.
