Local legend says this well was created when a legendary hero shot an arrow into the ground to find fresh drinking water — the more geological explanation is that it's a natural limestone sinkhole connecting to an underground water source that never runs dry, even in the harshest drought. Long dismissed as literally bottomless, a Sri Lanka Navy diving expedition eventually measured its actual depth at 52.5 metres, discovering several branching underwater tunnels along the way, one of which local legend claims connects all the way to the Keerimalai hot springs elsewhere on the Jaffna Peninsula. A broken ancient statue found near the well, now on display in Jaffna's museum, hints at an ancient site once standing here too.

Nature & viewpoints

Best time to visit

Any time of day — the well's appeal is in its story and unusual clear water rather than shifting light or crowds.

Visitor tip

Treat the well edge as a safety-sensitive area and keep back from the opening.

Local pick

Notice the well's water level rising and falling slightly every 12 hours — a tidal effect caused by its underground connection to the sea, easy to miss unless you know to watch for it.
