Monaco Observatory Cave

Monaco Observatory Cave


Located 100 m above sea level at the base of Monaco Exotic Garden, called the “Observatory” after a small astronomical observatory, an underground cave houses the famous Monaco Observatory Cave.  The calcareous rocks were excavated by carbon dioxide-rich water and it features numerous small caves with amazing concretions: stalactites, stalagmites, columns and many others.
The Observatory Cave guided tour is included in the Exotic Garden entrance ticket. The cave descends nearly to sea level and it is a favorite destination of local and foreign speleologists.
Also enjoy a visit of the Prehistoric Anthropology Museum featuring wide collections of animal bone relics which bear witness to the presence of prehistoric men in the area and of the climatic changes occurred in the last 250.000 years.
Monaco Exotic Garden is open all year round. Close on November 19th and December 25th.
15th May-15th September: from 9am to 7pm
16th September- 14th May: from 9am to 6pm.
