SEEHärma walls in the Piusa river ancient valley

The Upper Härma wall, is Estonia's highest Devonian sandstone outcrop.
The Upper Härma Wall, also known as Keldri wall, is Estonia's highest Devonian sandstone outcrop. At 150-metres in length, it extends to a height of 19 metres, compared to the valley's edge which reaches a total height of 43 metres. Lower Härma, or Kõlgusniidu Wall, is also close by with a total height of 20.5 metres. Lower Härma, a projecting rock face, is arguably one of the most beautiful walls in the Piusa Ancient Valley, well-known for its brightly coloured layers of clay and majestic pyramid shape. This beautiful area has the added benefit of being host to a fantastic campsite for those wanting to make campfires, located in the meadow at the bend in the river.
