Welcome to the Tunnel of Doom! Not really as scary as it sounds, but a really great waypoint along this short trail!
The Mike Miller trail is a fairly easy mile loop trail. There are a bunch of easy flat sections, but also a few spots of moderate uphill or downhill hiking. Overall though, it's a beautiful trail that can be done start to finish in less than an hour.
The cache itself should be pretty easy to find for seasoned cachers - the tricky part is the coordinates! The tree cover will make your GPS want to run home to its mommy.
