So at the end of this month I am doing an amazon excursion- of course. But it ends at 9am and our bus put of town doesn't leave until 9 pm. What is there to do for half a day? I'm sure we won't get back go PM from the lodge til like 11 or so, but that still leaves us a good chunk.any half day tours to do? Or an interesting part of town to see? I'm at a loss..
