On 17. June in 2005 there was opened a Kaali Visitor`s centre in the Kaali crater field. It is located 18 km from Kuressaare. For the building it was used traditional style of architecture. There was used a lot of Selgase limestone which is counted as the most beautiful limestone on Saaremaa. In the center there lies a Museum of Meteoritic and Limestone, a meeting room, a small hotel, a sauna and a shop.
The centre was built by nonprofit association Kaali Visitor Centre. Beside the centre the nonprofit association also looks after the craters. The craters have been cleaned of trash, bushes have been cut down and a new stairway with a platform has been constructed in the main crater. Now the craters are waiting for discovering.
Till now Kaali lake hasn't told its secret.
