Please be advised there are many pitfalls on the way out to this cache. The grass was about 5 feet tall when I went and you can't see the ground. A walking stick is highly advised so you don't fall into a creek. If you're fortunate you can catch this one when the grass is short and the rain is mild.
In order to get to this cache you will have to navigate a series of ponds on logs. Some log crossings are far between. I was able to make it while staying dry, but I also have very long legs. The terrain is more like a 4, but I gave it a 4.5 because most will have trouble staying dry. Have fun and happy caching!
Congrats to the FTF party for solving the labyrinth!
