Nuwara Eliya is a city in the Hill Country of Sri Lanka. Its temperate climate gives the city a very different feel from other parts of the country and, along with the colonial architecture, has earned it the name 'Little England'.
By train - the train journey from Colombo or Kandy to nearby Nanu Oya is spectacular. Easiest way to catch Colombo - Badulla train, Train Name is 'Udarata Menike'. Local buses run frequently from Nanu Oya to the centre of Nuwara Eliya. Three wheelers/tuk tuks are also present at the station.
By bus - buses can be taken from Colombo or Kandy.
Be aware - road transport between Colombo and Nuwara Eliya is very slow. The journey will typically take five to six hours to cover the 180km. Traffic, poor weather or failing light can extend the time needed. Rail transport is about the same due to the old and meandering track.
The town centre is small enough to walk around. To visit sites further afield, take a bus or hire a three-wheeler.
The same caveat applies to touring around the area as for getting there. Assume that you'll not exceed 20 kilometres per hour no matter what the mode of (ground) transport. So plan any excursions carefully, and don't assume that you can cover more than about 100km in a day, including stops.
Within the town itself there are a number of interesting sights. The Post Office is a very unusual building - a remnant of the colonial era. Victoria Park nearby is a pleasant place to spend an hour or so, with an astonishing variety of plants, ranging from tropical rain forest to English country garden.
The mountains in the central province of Sri Lanka and near to Nuwara Eliya are adorned with many picturesque waterfalls including Dunhinda Falls, Diyaluma Falls, Baker's Falls, St. Claire's Falls, Ravana Ella, Bambarakanda Ella, Aberdeen Falls, Laxapana Falls, The Lovers Leap, and Bridal Falls.
Take a walk up through the tea plantations south-west of the town to the top of Single Tree Mountain for a splendid view over Nuwara Eliya. From the hill top you can walk north for a couple of kilometres along the ridgetop to a nearby village and get a tuc-tuc/three-wheeler or walk back to town from there.
For more sightseeing you can visit Victoria Park and Hakgala Gardens. Lake Gregory lies less than a mile from the centre of town and offers a splendid and peaceful environment for sightseeing and boating. Boats can be hired from the area.
You can also explore the tea plantations and factories and stay at one of the colonial bungalows near the plantations for easy access and special tours.
Playing golf is also an option, along with heading to the racecourses (the only proper ones you'll find in Sri Lanka). These are both traditions left over from the colonial era.
Take a train trip from Nanu Oya towards Kandy. For the colonial experience book a 1st class ticket in the observation car. For an authentic local experience book a 3rd class ticket and hang out of the door of the carriage.
There are a number of accommodations in Nuwara Eliya, which makes exploring the city's wildlife and architecture more convenient.
