Loobu (river)
The Loobu is a river in northern Estonia. Its source is about 12 km southwest of Rakvere in Lääne-Viru County and it drains into Eru Bay near the village of Vihasoo in Lahemaa National Park.
Its drainage basin is rather small and narrow. The Loobu lacks any major tributaries.
At Joaveski, 10 km upstream from its mouth, the Loobu flows over the Baltic Klint, forming Joaveski Falls.
Kadrina is the only significant settlement on the river.
