On the trail of Donegal’s ‘secret waterfall’

As children and adults, we are often lured by ‘secrets’ – this promise of getting to know something that was hitherto unknown, or hidden. Of course, in the travel and hospitality industry, this word is often abused – ‘secret hideaways’, ‘secret getaways’ and the like. I have an inherent distrust of such deals or phrases, and sometimes they can also speak of privilege and exclusivity – as if some people are privileged enough to be able to gain access to these deals more than the others. Why were we then, on the trail of Donegal’s secret waterfall?
