Inside Crag Cave — Kerry's Million-Year-Old Underground World

Beneath the fields just outside Castleisland in County Kerry lies a world that's been forming for over a million years — and most people driving the N21 have no idea it's down there. In this episode of Come Trail With Me I head underground into Crag Cave, one of the finest limestone cave systems in Ireland. Stalactites, stalagmites, flowstone and chambers like the Cathedral and the Crystal Gallery — all at a constant 10-12°C, no matter what the Kerry weather is doing above ground.
