Raft through the roaring rapids of the Teesta River — Sikkim's main river flowing from the Himalayas through spectacular forested gorges to the plains. Rafting stretches between Makha and Sirwani (around 35 km) offer Grade III–IV rapids through dramatic landscapes.
Avoid rafting during monsoon (June–September) when the Teesta floods dangerously. Sikkim Tourism Board-registered operators are the safest choice for river rafting.
