By road
The popular route is from the north via Kandy. The A5 winds up through the spectacular Ramboda Pass. The climb is steep especially in the latter half and there is a gradual change in the vegetation from tropical profusion to the cool green of tea bushes and pines. Fog may be encountered at times. Distance is 77 kms from Kandy.
