I wish I could take credit for finding this place, but this is somewhere that The Boonieman told me about. He has a knack for finding locations like this, I think.
Parking for this cache is at approx N28°14.298 W82°25.822. You can bike pretty close to the cache, but will have to abandon it at some point and the last 1000 feet or so can be difficult riding. The total distance is about a mile each way.
The Boonieman's castle is surrounded by a moat. This is Florida, so you don't need me to tell you what dangerous critters you might find in the moat. Don't even think of getting in the water, and please don't leave the preserve and wander into the housing development...there's no way in from there.
There is an entrance, if you scout and observe, that will get you over the moat and through the first line of defenses for the castle. Then you'll need to make your way carefully along the ramparts where you'll be surrounded by water on two sides.
After a while an old bridge will present itself, guarded by mosquitos...make sure you bring some bug repellant. Getting across will require some caution and a good sense of balance. BE CAREFUL! Some of the planks have seen better days, so step cautiously. As always, you hunt this cache at your own risk. This is not a good cache for the kiddies, although they can wait behind at this point since the cache is very close by.
Cross the bridge, and you've entered the kingdom! The king has a wellhouse, a castle, and an open-air shelter (for royal ceremonies, no doubt).
Please re-hide the cache well, I think this area is occaisionally used by fishermen.
This is a such a cool place...thanks Boonieman for telling me about it!
