This tour is really good for people looking for a relaxing day on a boat. Prepare your camera because this tour is not short of a good time and an interesting peek into the lives of the people in Kerala. I saw people bathing in the river, washing their clothes there, and of course, saw many other boats and people on house boats. The weather wasn't great when we went, but it got hot when the sun was out. Also, the food on the boat was amazing. If you are vegetarian, there is definitely a vegetarian option, but I don't know about gluten free.
