Sinharaja is the last great primary lowland rainforest left on the island — a UNESCO World Heritage Site, dense with endemic birds, butterflies, frogs and mammals. It is the most biodiverse square kilometre of the country, and the natural counterweight to Yala for wildlife travellers.
- · Hire a registered bird guide — endemics are hard to spot otherwise.
- · Rain is possible year-round — pack a light shell.
- · Pair with Hatton or Galle for a Tea-Country–Rainforest week.
