Yes, you did just read that correctly. Every year, the leprechaun hunt takes place at Ireland's last known leprechaun habitat: the Slieve Foy Mountain. You can win cash prizes if you find special leprechauns that are hidden around the mountain. It costs just 5 euros to get a prospecting license. The best part? All proceeds go to charity.
I have a particular fondness of leprechauns. When I was in Dublin a few years ago, we traveled to the Irish countryside to visit Newgrange (which is an entire blog post of it's own). While we were waiting to see the tomb, I went on my own leprechaun hunt.
