A dream of mine would be to explore some Venezuela's Plateau's. Some of these are the size of greater London, mostly jungle and because of their inaccessibility remain unexplored.
Could there be tribal people living on them? Could there be new species of plants,birds, animals etc or could reports from tribes living at the foot of them be true about dinosaur like creatures?
Who knows?
If you would like to fund an expedition it wouldn't be too difficult to put a team of experienced amateurs together to explore these lost worlds.

Ok, Ok, after watching Sanctum i officially retired from caving (i unofficially retired a few years ago, with slight willingness to do little bits), but the film rekindled my heart for adventure.
Rethinking the caves i have been in there have been some awesome sights -
The (then) largest stalactite in Europe which we crawled for ages to see (it's now being opened up as a tourist attraction)
A cave/tunnel with floor, walls and ceiling lined in calcium; this lit up in blinding wonder when a torch was shone down it.
There's The Gobbins, an old victorian walkway carved in the cliffs, now largely unaccessible, but fun.
Abbeys, Castles, graveyard (through a cave system that went under it, stink & unsteady rocks caused a retreat), old buildings are perhaps my favourite.
I've seen friends fall as steps below them give way, only to be snatched from mid air, and saved by other friends (praise Christ for these mercies).
We've made our way to islands which are animal &/or bird sanctuaries.
And there's the thousand trips i've missed
In recent years my desire for this has been sleeping. But the guys have continued with 160ft abseils to the mouth of caves, old mine shafts, castles on islands . . . the list of where these guys go is amazing . . . that they all come back is perhaps even more amazing.
