Just came across a nice website called Gothisplace which allows you to identify attractions in a given surrounding area.

It’s not perfect though. I noticed one park in the wrong place on the map and a couple of country parks which hadn’t been included at all, but it’s relatively useful when you’re stuck for ideas.  The search option is relatively straightforward, and while it reset itself to the area surrounding Hamilton, it was easy to fix.

Overall, not a bad guide to what’s around, but probably more useful for areas you don’t know so well.
