Hiking Geocaches

I'm not into the city geocaches very much. Anyone found a good way to find only the hikes / scenic ones?

I've been using http://www.trailtip.com/ but it needs a lot more hikes added.

I usually just look at them on a map. I also do them with my kids, so I make sure to look for only traditional caches that are "regular" or "large" in size. These also tend to be outside the city.

Another easy way would be to pick a point out in a national forest or somewhere you want to hike and then search for some in that general area.
