Flash flooding caught visitors off guard during a tour of the Marble Arch Caves in Fermanagh, including tourists Kim and Alistair Hay. Around 30 minutes into the guided walk, torrential rain triggered waterfalls inside the caves and momentary blackouts. The group was forced to walk through rising water and upstairs turned into a rushing waterfall to reach safety. Despite the frightening experience, visitors praised the guides for their calm and professional response in what staff described as an unprecedented event.
