A while back, there was an underwater T5 cache out by a ferry terminal called Swimming with the Ferries that required the use of specialized equipment to reach. As someone who has received training to use such equipment, I had been meaning to go and find that one for a while, but unfortunately health and time issues got in the way. That cache has since been laid to rest in the Geocaching archives, so I figured I would make my own tribute to it since I never got a chance to put my name on the logbook.
This one is a slight T challenge, but requires no specialized equipment other than sturdy walking/hiking shoes and perhaps a hiking pole. Coordinates might be a bit unstable due to the tree coverage but just follow the trail and you should be good. There is no need to enter private property. I have also made attempts to clear the trail of any branches and debris, but it would still be wise to watch your step. I strongly do not recommend attempting this one when it is raining or snowing due to the steepness of the area. GZ is out of sight of muggle traffic but please re-hide with the cache container facing away from the front.
