And they let me know online. "Thnks for letting evryone no. I won't be going bck" read one message promptly hammered out with angry fingers.
A flurry of rapidly tapped typos, the anger palpable as in their hurriedness to get the message across, they'd skipped letters in favour of a hasty response.
But where had I discovered this bastion of bathing? This Atlantis of the New Zealand bush? The secret map was not handed down through the generations from my father's father's father to me, nor was it whispered to me in the corner of some dark alley. No.
I googled it.
It was the second result on the page when I typed in Hawke's Bay hot pools. And there was only one other person there when we went to check it out!
Turns out getting there is a little bit of a mission, and to just drive out for a quick dip is not something you'd do every day!
Thankfully the rest of the responses were overwhelmingly positive, and it seems like loads of us have made the journey across the river, along the gravel tracks, and out to that small but amazing piece of New Zealand.
Now If only I could convince someone to give me the co-ordinates for that 20 pound snapper.
