Why Sinharaja for a weekend
Sinharaja is the best rainforest weekend from Colombo. The reserve protects Sri Lanka's largest remaining tract of lowland rainforest, with very high levels of endemic species among its trees, birds, amphibians and reptiles.
A weekend gives two morning walks, the best time for birds, with afternoons for rest, a waterfall or a night walk for frogs and insects. It suits birders, naturalists, photographers and anyone wanting a complete change from the city.
Accommodation near the forest is simple, from eco lodges to guesthouses, with views over the canopy from some.
- →Lowland rainforest, UNESCO-listed.
- →Endemic birds, frogs and reptiles.
- →Simple eco lodges near the edge.
Getting there and the entrances
Getting to Sinharaja from Colombo takes roughly 3.5 to 4 hours to the Kudawa entrance on the northern side, via Ratnapura and Kalawana. The southern entrance at Deniyaya is closer to the south coast and further from Colombo. Most weekend visitors use Kudawa.
The last stretch to Kudawa is narrow and can be rough. Lodges near the entrance may arrange a four-wheel drive for the final approach.
Leave Colombo on Friday afternoon or very early on Saturday to reach the forest for an afternoon walk.

Guided walks and birds
Guided walks in Sinharaja must be led by a licensed local guide, usually from the villages around the forest. Morning walks of three to five hours follow trails along streams and ridges, stopping at waterfalls such as Duwili Ella and looking for mixed bird flocks.
Mixed flocks are the highlight for birders: noisy groups of many species moving through the canopy together, often led by the orange-billed babbler and including endemics such as the Sri Lanka blue magpie, the red-faced malkoha and the Sri Lanka spurfowl.
Night walks, where permitted with a guide, reveal frogs, lizards and insects.

Leeches, rain and comfort
Leeches are part of Sinharaja. Wear leech socks, which guides or lodges often supply, long trousers tucked in and closed shoes. Leeches are harmless but bleed freely; salt or a flick of the fingernail removes them.
Rain falls in every month, though roughly January to April and August to September are usually drier. Carry a rain jacket and a dry bag for cameras, and expect humidity.
Comfort in Sinharaja comes down to clothing and pace. Quick-drying trousers, a breathable long-sleeved shirt and light walking shoes with grip suit the muddy trails. Walk slowly, stop often and let the guide find the birds; rushing scares the flocks and tires you in the humidity.
Planning a Sinharaja weekend
A private car and driver makes a Sinharaja weekend from Colombo practical, with lodges arranging guides and final transfers. Lankan Stays & Trails can arrange the car, a lodge near Kudawa and a licensed guide.
Combine the weekend with Ratnapura's gem pits on the way, or with Kitulgala for an active two days in the wet zone. Pack quick-drying clothes, binoculars, insect repellent and a torch.
Afternoons at the lodge are part of the weekend. Many lodges near Kudawa have verandas over the canopy where hornbills, barbets and drongos pass, and a quiet hour with binoculars after lunch often adds species missed on the morning walk.
