My kids (currently 3 and 6) and I have been geocaching casually for about a year now, and they've been dying to place one of our own! This one is LOADED with stuff for the kiddos.
Park at the Lodge and look for a trail in the direction of the cache. Once you get to the open area with a picnic table, look to the title for the trail to take. These trails are poorly maintained, but you might be able to follow the blazes and do a bit of bushwhacking. Suitable for all ages as long as everyone is wearing sneakers. This might be winter-friendly--I've snowshoed this trail many times but you'll probably have to dig to find the cache. Happy caching!
