It was pretty much the coolest thing I've ever done. Cool doesn't even come close to describing it, though. We (my 2 great travel companions and I) flew in a Cessna right by the falls, spent one night in an indigenous Pemon village, canoed down the river to the base of the falls, slept every night in a hammock IN THE RAIN FOREST!!! (under a shelter, of course), saw howler monkeys, can you believe it? Hiked in the rain forest, saw a million kinds of plants and animals, felt like I was living my dream of being a NatGeo photographer -- we saw lion ants and giant hairy spiders and kingfishers and cormorants and cock-of-the-rock and tanagers and macaws and orandopola nests and we looked REALLY hard for a tapir but we didn't see one.
I learned a ton too, like how Angel Falls is the tallest uninterupted (free-falling) waterfall in the world (you may recognize as the inspiration for UP), how the tepuyes (giant mesa-mountains) and the canyons cause wind and cloud formations unique to the world - their own microclimate! How the Pemon people build huts with palm-tree roofs that last up to 15 years, and how they season their chicken soup with this great tasting spice that comes from crushed red ants (we found that out afterwards, but it was really good!).
We had a great time with our guide and canoe crew (motorized, so none of us had to paddle, but I tell you, Capitan sure did know how to manuever that thing -- he would swing across to the other side of the river to avoid rapids just around the corner that no one could see coming, amazing!). Oh, another highlight: we pulled ourselves up a rope through a river to see a waterfall at the end of this gorge. Wow, what a rush.
Anyway, I had the best time ever, my internet is being awfully slow right now so I'm not able to upload more photos, but you can check out all my photos here. But I'll leave you with one parting shot, looking up from the base of the falls:
