Been jonesing about Ec since I was there last Feb. Chase down this girl, she was a guide/kayak instructor from NOC and spent a winter in Ec
mostly in Banos, which is the other ww center (Tena being the one folks mentioned.)
Lots of folks mentioned SWA. The other group that runs trips that might take you on as an assistant guide is AdventureKayaking.com
Mary and Phil DeReimer run kayak trips with clients from Rio Quijos down to Tena and they might have some info.
Write quick, they are headed to Bhutan.
You might be looking for paddle boat gigs, but they obviously know the score down there.
PS I was nervous nelly venturing around by myself on the bus. But I loved it in the end, much easier than you think. Even if you can barely say Que tal.
My highlight, the market in Guamote. see probici.com for more. You in Quito now or where?
