On this two-day trip out of Hanoi, we passed trucks loaded with pigs, and dozens of duck farms, all supplying restaurants in Hanoi. At the Cuc Phuong National Park’s conservation center, we were hoping to spot a pangolin (a rare, scaled animal that, in photos, reminded me of an armadillo), but they were only on view at certain times of day, so we missed them. We did visit the monkey and turtle sections though. After a night in our Ninh Binh hotel, we visited a temple and then boarded a small, flat-bottomed boat for another river trip where all the rowers used their legs and feet at the oars. Dozens of tourist-filled boats joined us as we made our way down the river, past even more spectacular scenery, and through three low-hanging caves. I was sure we would have to duck or bump our heads, but the rowers knew the safest channel to take. Outside the caves we encountered a floating market of sorts. Several sellers in boats tried to entice us to buy their wares, imploring us to at least buy food for our rower.
