We were about 16 hours on the road and looked at something for a maximum of 4 hours. From Bentota, this excursion is quite strenuous. In the botanical we had an hour. That's a little bit of time but it wasn't that nice either. The botanical garden in Kandy should be better. A visit to the tea factory is also superfluous. You will be told a bit about the different types of tea and how they are made. But in the end they only want to sell tea. I would have liked a little hike through the tea fields better. What is definitely worth it are the impressions in the highlands. This is really nice.
