Diyaluma Waterfall: Diyaluma is the 2nd highest waterfall of Sri Lanka with a height of 559 foot. Fed by the Poonagala Oya, the fall is13 km from Wellawaya town and 6 km from Koslanda in the Hills. The fall has a folklore attached to it. According to a legend Gods, seeing the heartbreak of a prince whose runaway romance ended in the death of his sweetheart whom he had tried to haul over the Diyaluma precipice, created this beautiful cascade to weep forever in the wilderness.

The Diyaluma Falls is a 220-metre high waterfall on the Punagala Oya located very close to the A4 road between Koslanda and Wellawaya. The Punagala Oya rises from the Mahakande pass and flows into he Kuda Oya, a tributary of the Kirindi Ganga, which flows into the sea near Tissamaharama. The Diyaluma Falls, the second highest in Sri Lanka, is the last of a series of waterfalls on this river. It is an impressive sight when you stand almost directly beneath the waterfall on the road. The water appears to be propelled over the cliff face and falls in one long and clear drop to a pool below beside the road. Above this big fall are several smaller waterfalls and rock pools. They can be visited by walking about 500 metres down the road and taking the estate track that turns of sharply to the left. Proceed for 15-20 minutes along this track until you come to a rubber factory, where you turn off left uphill. At the top, where the path forks, take the right branch, which leads to the pools above the main fall.

Diyaluma falls fed by Poonagala Oya could be seen from Koslanda – Wellawaya road and is 13 kms from Wellawaya town. There is a legend behind Diyaluma falls and the people believe that this is a work of a god for a young prince to weep forever in this wilderness, whose runaway romance ended in the death of his beloved.
