The biggest white sandstone outcrop in Baltics – 15 m high and 400 m wide. In the sun it warms up and keeps warmth, hence, wild bees have chosen it as their home, creating the unique honeycomb in the walls of the outcrop. There is a well–established nature trail with several viewing platforms. Places for picnic are available, as well as information stands and a parking lot.

It is considered to be one of the highest rocks in Latvia, an excellent viewing place is located at the highest point of Sietiņiezis Rock.

Sietiņiezis Rock reveals sandstone formations and ornaments, which have formed over millions of years of natural processes!

The rock is like a luxurious, beautiful and bright sandstone castle designed by nature itself. It has formed over millions of years of natural processes, which are still at work today, shaping the face of Sietiņiezis (Strainer) Rock.

Sietiņiezis Rock is very diverse – it has an arch in the making, a huge pillar, a cave with two exits, high cliffs and nooks.

Its sandstone surface is dotted with tiny holes that distinguish Sietiņiezis Rock from other rocks.

It is the similarity to a strainer that gave way to the rock’s name.

As the rock preserves the heat of the sun, a species of wild ground bees have chosen it as their home. The little holes were created by these bees, which constantly buzz in an out of them!

The highest point of Sietiņiezis Rock, the tower of this natural castle, offers a picturesque view to the beautiful blue ribbon below that is the river, adorned with bright green lace of tree branches.
