I give this tour 3 stars because the homestay was nice, the food was delicious, and the park is beautiful with friendly people who wave at visitors. However, our tour guide did not talk much perhaps he was not overly confident with his English, as he was a little difficult to understand at times. Practice makes perfect! Anyway, he seemed pretty disinterested in giving us more than the bare minimum of information he would identify the sites we visited, but with little to no background information. We had hoped to learn a little about the park's history and the minority groups that call the place home...that didn't happen. When it wasn't required of him to speak, he just played around on his phone. Also, we were disappointed that certain things in Viator's tour description did not happen. On the first day, the options of walking or cycling and fishing or kayaking were not presented to us. We just drove to a cave which we went inside, then drove to a waterfall, and drove through a couple of villages without actually visiting them. And during the boat trip on the second day, we did not visit Puong cave as advertised. I'm not sure if these things were eliminated from our tour due to the cold weather if not, Viator's description needs a little editing. Overall, the park is definitely worth a visit if you have the time, but perhaps choose a different tour. And make sure you dress warmly if you're there in the winter, it does get quite chilly up there in the north, especially on the lake.
