I'm planning to go to Guanjo, then San Isidro and Wild Sumaco this July. I see that Papallacta is on the way from Quito to Guanjo, and has Seedsnipe, Jameson's Snipe etc. Is it an easy side trip? Do I need to give half a day or so to this area? Is the best spot the Radio antenna (as ebird suggests)? Basically, what's the best way of incorporating this area into my plans?
