The very famous and stunningly beautiful train ride from Colombo (via Kandy) to Ella, high up in the tea mountains of Sri Lanka. If you're lucky enough to find a window seat, or any seat for that matter, strap yourself in and enjoy the beauty of Sri Lanka's countryside.
India is thick with wildlife. Take for example, the roads, littered with elephant, monkey, goat, dog, camel, sheep, etc. Don't be mistaken, not all of them are friendly either, the monkeys in particular will gladly take a bite out of your Achilles.
