It's really cool to see all of the vegetation. The river is flanked on both sides by hundreds of mangrove trees whose exposed roots belie the fact that the river was at low levels. The trees had very impressive roots. Some trees housed basket ferns. Crocodiles were hiding amongst the trees in search of unsuspecting fish. We saw a few different types of fish, but the crocodiles and trees were the main attractions.
Our boat's navigator was quite a character, and he made the cruise very enjoyable. His name was Bob, and he was a very enthusiastic narrator. He had been giving cruises for years. The entire trip lasted about an hour, and it was definitely worth it.
