Might be a little out of your area... Depends on how far you want to travel.

Take a look at caches by Marrow Bone.
I've done a few of his as cache and dash, but have a good idea of the areas he has hidden in, and they are worth a walk.
He does set a series of caches with a named theme, and says in the description how far the walk is.

(I reported a Needs Maintenance on one of his caches, and he fixed it within days!)
