Like many countries, Morocco for example, Ecuador is focused on ocean fishing at present and fresh water fishing is not yet on the radar. From facebook post, none within 2 years, I guessed that you could take a bus from Quito to Papallacta and fish the streams in the high Andes coming out of the Cayambe-coca Ecological Reserve.
Brenda and I booked a night at the hot springs resort Termes del Papallacta. It looked to be about 2 hours away on an iffy road well up in the Andes on the way to the jungle. We were just finishing a tour of Machu Picchu and the Galapagos so I asked our tour leader to help me get a reliable taxi. He hooked us up with the transit company for the tour. It seemed a little salty at $75 but at least I had recourse if things fell apart. This is the vehicle that showed up to take us and only us to the resort. The road turned out to be new highway with little traffic and not nearly a scary as the 8 hour trip from Santiago, Chile to Mendosa, Argentina over the same mountain range.
