Mahaweli River exploration is one of my dream trips. Mahaweli River flows from Hortain plains and ends at Trincomale. If someone wants to go along the river (by boat or foot) it is possible only from Mahiyangana (මහියoගණය) to Trincomale. From Central hills to Mahiyangana, the river is guarded by major reservoirs.
During dry season (especially August and September) it has low water level.
My friend Siraj suggested me to walk along the River from Manampitiya as he has noticed the river with low water level when he visited to Thummodara (තුම්මෝදර).
