Hey JARS,
On the scenic side, you could try the River Stroll Series that goes through Springbank Park and some of the trails system (paved). It's a very nice area -great for a picnic. If you have wee ones, you can visit Storybook Gardens while you are there. We did the series on bikes, which is a fun way. It can be a busy spot on weekends though, and it's more of a park series - not wilderness. As an added bonus, several caches are near by, should you have the time.
In terms of unique, the two most unique ones I can think of are London Transit, where you take the cache and re-hide it (in London) and Get Clicking - a webcam cache in downtown. Make sure you get the coordinates for London Transit from the last log, not the cache page.
Hope this helps,
