The vehicles I've actually used for day trips around Kandy — no self-drive rentals, just what got me there.
The three-wheeler I actually book for day trips out of Kandy — driver included, no self-drive nonsense.
What I book when it's a group, or the route is long enough that a tuk-tuk stops being fun.
A quieter, air-conditioned option for rainy days or when I just want to sit still between stops.
