Went there a lot as a lad myself. Big boulder field and a nature trail. Boulders have a high iron content so when you hit them with a hammer they have a bell like ring, minus the sustain. There's a box at the trail head marked "take a hammer, leave a hammer". The kids, almost 2 and almost 4 years old did incredibly well navigating the terrain. Are there other parks with niche attractions like this? Not necessarily a come beat rocks with a hammer park, but something of that sort of odd. I saw that there's a ringing rocks in Montana, according to Wikipedia.

There is more to those rocks than iron content. We have no idea why they ring when you strike them. If you move them out of place they no longer ring. It’s a resonance that goes through the whole pile of rocks below them. There are other stones and man made objects around the world that have the same property. It might be a natural fluke, or it might be something an ancient lost civilization could do to stone. We don’t know.
