Tenaru Falls, Waterfall in Guadalcanal, Solomon Islands.

Tenaru Falls is a waterfall on Guadalcanal that drops about 63 meters through thick rainforest, crashing over natural rock ledges. The water creates several smaller cascades before collecting in a quiet pool at the base.

This waterfall sits in an area that saw military activity during World War II, when fighting occurred near the Tenaru River. Remnants of that period still exist in the surrounding landscape.

The falls pour into the Chea River about two kilometres from a small village, and that village is the usual starting point for the walk to the water. Villagers know the route through the Guadalcanal rainforest and are the people to ask about going up.

Reaching this waterfall takes about four hours for a round trip hike, with multiple river crossings along the way, so sturdy shoes and waterproof gear are needed. Starting early and bringing water and snacks will make the walk more comfortable.

Tenaru Falls drops 63 metres into the Chea River, and the pool at its base sits roughly two kilometres from the nearest small village, so the walk in passes through rainforest rather than farmland.
