Trekking in the Sinharaja Rainforest offers two main entry points: the Kalawana side and the Deniyaya side, each providing a unique experience in this UNESCO World Heritage Site. The Kalawana side, accessed via Kudawa, is known for its dense trails, towering trees, and sightings of endemic bird species such as the Sri Lankan blue magpie and the red-faced malkoha. This side has well-marked paths and offers a more structured trekking experience, with guides often leading you through lush jungle corridors rich with biodiversity.

The Deniyaya side, however, offers a slightly more rugged and adventurous route, appealing to those looking for a quieter, less-traveled path through the rainforest. Known for its natural beauty, Deniyaya’s trails pass by pristine streams and lead to enchanting waterfalls hidden deep within the forest, ideal for a refreshing dip. This entry point also offers more opportunities for spotting mammals like the purple-faced leaf monkey and rare amphibians. Both sides provide stunning glimpses into Sinharaja’s unique ecosystem, whether you’re there to explore endemic species, trek beneath a towering canopy, or simply immerse yourself in the tranquil, mist-laden atmosphere of one of Sri Lanka’s last remaining rainforests.
