The last surviving rainforest  

Blessed with rich biodiversity, the Sinharaja Rainforest is home to a wealth of endemic species and amazing flora and fauna. It is truly a paradise for nature lovers and birding enthusiasts. For those who are wild about wildlife, there are Sri Lanka tailor-made holidays that will give you the best wilderness experience.  

Sinharaja is sadly one of the last remaining primary tropical rainforests in Sri Lanka. This is one of the top locations to visit for nature lovers. The forest’s unique bio-diversity with a rich diversity of vegetation and animal life was a reason it was declared a world biosphere reserve and world heritage site. The name Sinharaja translates to ‘Lion King’ in Sinhala.  

Exploring the Lion King  

Declared a UNESCO World Heritage Site, Sinharaja Forest is located in the country’s wet region. Early morning hikes are the best so that you get to explore a few hours before rainfall.  In comparison to the other reserves in the world, Sinharaja is not so big however it is truly a fortune in terms of natural resources. You find endemic species including trees, insects, birds, reptiles, amphibians, and mammals. The number of elephants and leopards seen here is less than in other national parks in the country, however, the purple-faced langurs make up for that. Bird watching is popular at the reserve since out of the 26 endemic birds in the country, 20 are found here.  A variety of reptiles can be seen here including the Green Pit Viper and Hump Nosed Vipers. One thing you need to watch out for, are the clingy leeches!

Travelling to Sinharaja 

You can use public transport such as the bus or a train to travel to get there. However, the most convenient way is to rent a car with a driver. Not only will you be able to get down at the entrance of the forest but also it would make life much easier especially for someone unfamiliar with the Lankan roads.  

Getting there from Colombo  

You can reach Sinharaja from three access points. From Colombo the easiest route is to travel through Horana– Mathugama road then enter the forest through the entrance point in Kudawa 

Getting there from Southern Coast 

If you are coming from the south of the country you can go to Deniyaya and enter the forest through the Pitadeniya entrance point which is on the southern end of the rainforest.  

East end entrance  

There is also an entrance from Suriyakanda to enter the forest from the east side of the forest.

The Sinharaja experience 

There is only one way to enter the forest, which is on foot. You need to be accompanied by a national guide when entering. There are three entrances to the forest and the most commonly used one is via Deniyaya. The guide will give you an in-depth explanation of the forest’s ecosystem and help you unveil its beauty. Depending on which side you enter the forest, you may have the option of swimming in a freshwater lake below the waterfall. The trek can be customised according to your needs and fitness level. The paths can get muddy and slippery especially during the offseason.
