There is a trail I used to go to with my parents called Mill of Kintail. It has a few real hiking trails and a nice easy loop for those less coordinated. We took D there for a little run around and she had a BLAST!
It was almost impossible to get a picture of her face. She was an actual blur of activity the whole time. It was great though. Took about 40 minutes to get those tiny legs around the smaller-easy loop but I think it's safe to say we will be going back
