We happened to go towards Cape Zanpa and decided to check out the view from the apartments that are sitting right on top. The view is indeed amazing and then we saw a person snorkeling in the most amazing blue waters.
Instantly we are on a mission to find the way down there. We take every turn possible we come across a dirt bike course, a golf course, tombs en mass, and several dead ends.
Finally I spot the path.
This will not fit into the categories that my German nature created. This is for the adventurous. Please do not bring small children. Please do not go if you are afraid of heights.
I would suggest going on a "snorkeling date" to this spot.
Since this does not fit any of categories there will be no rating for anything.

Here we go:
This is for the snorkeler and diver in you. If you like Maeda Flats, but HATE the crowds this is for you.
A little difficult to find, somewhat hard to get to, well worth it.

Directions:
From Kadena Gate 1 make a right and go north on 58. Turn left on 6. Pass Torri Station, keep going. There will be a sign towards Cape Zanpa that points straight. Rt.6 will continue down the hill to your right. Go straight towards Cape Zanpa. Pass the houses on your right and keep going. You will now have sugar cane on your right. There is a vegetable stand with a mirror and a road on your right.It is important to have all three things together as there are many vegetable stands.
So now you turned right and are going down a dirt road. You will soon come to a junction of some kind. There is a path leading to your left, straight, and to your right. If you are in a vehicle that has some clearance keep going straight by all means. You will know when to park. If you are in a Kei-car, like me, park and walk down the path straight ahead through the sugar cane.
Follow the path, you will find remnandts of a road. It will veer of to the left somewhat. The path to the right leads to the dirt bike track that you found if you turned too early. Yes, I checked them all!
The path will narrow and turn down to the right and down. Follow it and you will come upon ropes and cables to hang on to on your way down.
This is it.
don't bring too much gear, as you have to carry it back up, and enjoy!
