Minor Park is a fun trail if you have some time to explore. If it is not being littered on or dumped on, it is very pretty. Look our for hikers as well.
How to get there:
I-435 to thw Wornall exit. Head south until you get to Red Bridge Road. Take a left and head east. You will go over train tracks and over a "Red Bridge". There is a park entrance to your right. Go to the very end of the road and the trailhead is down a small hill.
You may want to take someone with you, it is very easy to get lost in here.
