The Horton Plains National Park is not to be missed when visiting Nuwara Eliya. Leave your holiday bungalow in Nuwara Eliya by early morning to visit the sanctuary. If you get there early, take the very popular Worlds End Trek. The loop trail takes about 8 hours to complete and is very rewarding. You will head out to the Worlds End look-out point from where, on clear days, you can see all the way to the coast. Head back past the Bakers Falls, one of Sri Lanka's top waterfalls. The park is home to many wildlife and unique flora. Plus, you will spot plenty of sambar grazing peacefully on the wide open plains.
