Most difficult cache

[Newfie]

I'm curious, what's the most difficult cache ever hidden? Difficulty is subjective of course, what someone might think of as a tough hike someone else may consider a pleasant ramble. But there has to be elements of true difficulty that everyone can agree on. For example, I would consider anything involving scaling cliffs on ropes to be difficult. Anyone, anywhere, know of any true challenges?

However, what we really need is a more robust search engine for the caches. See this thread for Jeremy's response. Something should be coming soon that can help answer this particular question.

For my income and my 2 cents the most difficult cache is

Necker Cache (British Virgin Islands)

http://www.geocaching.com/seek/cache_details.asp?ID=1052 (N18 27.080 W 064 45.047)

It will cost me $10,000 plus air fare to visit this cache.

I have the nautical charts of the area and have studied it well. There is only on entrance by water to a guarded pier. There is only one entrance by air and that by heliocopter and you must have permission to land as a guest. Even as a Sailor and Scuba diver I can't cross the reefs on the opsite side of the island an sneak ashore on the private land. Not that I am suggesting I would ever consider doing such a thing. This give real meaning to a Difficulty level 5. I think is is not properly identified. I belive it is a 5.5 because it is nearly impossible.
