Sources say the cave is diveable all year (since the Lake Kallvatnet dam reduced the river flow in the 1960s); the local dive centre Plura Valley operates all year. No source names a best month, so every month is shown as good. Winter dives are done through a hole cut in the ice at the entrance basin (Dive Rite trip report, March 2020).
