You will want to park on the South side of the lake in the large parking lot. Begin your trek on the paved bike path, then on to a grass path, and finally a little bushwhacking to GZ. It's a nice walk and if you are quiet, you may see deer. They love this protected area.
During summer months, be aware of the healthy mosquito population and some poison ivy at ground level as you near the cache. Long pants should protect you.
This area is prone to flooding in the early spring.
