Spanning a vast 15,000 square meters, the Exotic Garden is a lush paradise brimming with a thousand varieties of cacti and succulent plants, each boasting stems or hypertrophic leaves that cleverly store water. These fascinating plants hail from the world's major semi-arid regions, yet they still manage to burst into bloom with vibrant flowers. The garden comes alive during the principal flowering seasons: winter, from January to February, when South African succulents like Aloe and Crassula show off their colors, and spring and summer, when cacti, native to the Americas, steal the spotlight. Towering trees line the garden's paths, silently narrating the history of this remarkable collection. It was Prince Albert I who dreamed up this botanical wonderland, and it opened its gates to the public in February 1933. In the 1960s, a botanical center and specialist tree nursery were added, further enhancing its allure. Today, it stands as one of the Principality's most cherished tourist destinations. Nestled at the base of the cliff where the Exotic Garden perches, known as "the observatory" for its long-standing astronomical observatory, lies a captivating subterranean chamber. This chamber, situated 100 meters above sea level, is a marvel of nature. Water infused with carbon dioxide has carved the limestone rock into a stunning labyrinth of caverns adorned with geological masterpieces: stalactites, stalagmites, draperies, columns, and soda straws. Entry to the Exotic Garden includes expert-guided tours of this mystical cave. The tour takes visitors on a journey from a depth of 98 meters to 40 meters, covering around 300 steps. The chamber descends nearly to sea level and is a favorite haunt for local cavers. Evidence of prehistoric humans residing in the cave region is revealed through the animal bones left behind from their meals. These remnants also serve as a testament to the climate changes that have occurred over the past 250,000 years. If you’re a history buff or a nature enthusiast, this garden offers a captivating glimpse into both the distant past and the vibrant present.
