This is defintely one of my favourite places in Estonia! It reminds me of Seitan Limania, which is in Crete or the Eilat mountains in Israel. It doesen`t look like Estonia at all. The ash hills are so strange yet beautiful and the water is so blue and clear, and yes, reminds me of Greece.
The Rummu quarry is located in Rummu, only 50 km`s from Tallinn (the capital of Estonia). The quarry is close to abounded prison, which is also a really cool place to explore.
It was my third time there and I think it`s going to be my mustvisit place to visit every Summer. So if you happen to be in Estonia, Rummu quarry is definitely a place to visit. It`s a cool place with interesting history and I totally recommend you to go there and enjoy this picturesque and odd landscapse.
