Kanneliya is the second great lowland rainforest of the wet zone and it gets a fraction of the visitors Sinharaja does. That is the whole argument for coming: the same forest type, the same endemics, the same waterfalls, and trails you will often have to yourself.
It also holds animals that are barely findable anywhere else. Nagao’s pug-snout frog was described from this forest and breeds in water-filled holes in old trees. The Sri Lanka tree crab does the same thing, a freshwater crab that spends its life in a tree, which is about as unlikely as an animal gets. And the Sri Lanka relict ant, one of the rarest insects on earth, has one of its few known populations in this leaf litter.
For most visitors the day is birds, butterflies and frogs. Orange-billed babblers work the trails in noisy parties, the blue magpie comes through with the feeding flock, purple-faced langurs are regular in the canopy, and the streams carry cherry barb, black ruby barb and the ornate paradisefish. The butterfly list includes the Ceylon rose and the tree nymph, which drifts through canopy gaps like paper.

Planning
January to April and July to September for the drier weather, though this is rainforest and rain is the normal condition. The main trails run to waterfalls and are straightforward; the interesting herpetology is off them and needs someone who knows the reserve. Leech socks in any month. Kanneliya is smaller and more fragmented than Sinharaja and the buffer is under real pressure from cultivation. If you want the endemic birds and one forest only, Sinharaja is the stronger choice. If you want the same forest without the guided queue, this is it.

Frequently asked questions
What wildlife can you see at Kanneliya?
Wet zone endemics: Sri Lanka blue magpie and orange-billed babbler among the birds, purple-faced langur, an endemic frog list including the golden shrub frog, endemic stream fish, the fringed ornamental tarantula, and the Sri Lanka tree crab and relict ant, both close to unfindable elsewhere.
Is Kanneliya better than Sinharaja?
Sinharaja is richer for birds and has the mixed feeding flock. Kanneliya is quieter, easier to walk and holds several species that are hard to find anywhere else. If you have time for one, take Sinharaja. If you have time for two, come here second.
When is the best time to visit Kanneliya?
January to April and July to September, the drier spells. Frogs are better on a wet night, so the two goals pull in opposite directions and most people take the dry option.
Do you need a guide at Kanneliya?
Not for the main waterfall trails. Yes, for anything on this page that is small, nocturnal or off the path, which is most of the reason to come.
