Quick answer
Sinharaja is better for endemic birds, especially the large mixed feeding flocks that can include the Sri Lanka blue magpie, and for its status as a UNESCO World Heritage Site, but it is roughly two and a half to three and a half hours from Galle or Colombo. Kanneliya is better for an easier, quieter rainforest day from the south coast, roughly one to one and a half hours from Galle, with many of the same species, waterfalls and fewer visitors. Choose Sinharaja for serious birding; choose Kanneliya for convenience.

The verdict
Sinharaja is the better choice for birders and naturalists who want the best chances of Sri Lanka's rainforest endemics, especially in mixed feeding flocks, and who can spend one or two nights nearby. Kanneliya is the better choice for travellers staying on the south coast who want a rainforest day without a long drive, and who value quiet over a long species list.
Many travellers who visit both find Kanneliya a good introduction and Sinharaja the deeper experience.
Both reward patience more than distance walked.
Birds compared
Sinharaja's birds are its glory. Mixed feeding flocks can bring dozens of species together, including the Sri Lanka blue magpie, red-faced malkoha, orange-billed babbler, Sri Lanka crested drongo, ashy-headed laughingthrush and white-faced starling. A local guide can find most endemics in two or three walks.
Kanneliya shares many of these species, and flocks are common, though often smaller. Birders usually see fewer endemics in a single day at Kanneliya, but the forest is quieter, and sightings can be very good.

Frequently asked questions
Is Sinharaja better than Kanneliya?
For birding, usually yes. Sinharaja has the best mixed feeding flocks and the most endemics, and it is a UNESCO World Heritage Site. Kanneliya is quieter and much closer to Galle, with many of the same species, which makes it better for a convenient rainforest day.
How far is Kanneliya from Galle?
Kanneliya Forest Reserve is roughly one to one and a half hours by road from Galle, via Udugama. It can be visited as a day trip from Galle or the south coast beaches, though an early start gives the best birds.
How far is Sinharaja from Galle?
Sinharaja is roughly two and a half to three and a half hours from Galle, depending on the entrance. The southern entrances at Deniyaya or Pitadeniya are usually closer from the south coast, and Kudawa is closer from Ratnapura and Colombo.
Can you see the blue magpie at Kanneliya?
The Sri Lanka blue magpie occurs in both Sinharaja and Kanneliya, though it is more reliably seen at Sinharaja, where mixed flocks are larger. A local guide improves the chances at either forest.
Do I need a guide for Sinharaja and Kanneliya?
Guided walks are required at Sinharaja and recommended at Kanneliya, where some trails may also require a guide. Guides know the trails, find endemic birds and other wildlife and help visitors stay safe on slippery paths.
When is the best time to visit Sinharaja and Kanneliya?
The drier windows, roughly January to April and August to September, are best for both. During the monsoons, roughly May to July and October to November, rain is heavy and leeches are common, though the forest is lush and frogs are active.
Can I visit Sinharaja as a day trip?
It is possible but not ideal, as the drive is long and the best birding is at dawn. One or two nights near Kudawa or Deniyaya allow early walks. Kanneliya works better as a day trip from the south coast.
