Why should you visit Biševo island and it's Blue cave?

Island vis archipelago - global geo park - unescoBiševo island is a pretty small and uninhabited island near the island of Vis, but it hides one of Croatia’s best natural beauty spots – the breathtaking Blue cave Croatia. Like most sea caves, this one was also formed by the action of sea waves that eroded the limestone rock over time. They have created a small entrance, only 2.5 meters wide and 1.5 meters high, making the entry into the cave exciting with a pinch of adventure-like feeling. But then, once you “step” inside, there is a whole other world – something like the Narnia closet, just a summer version of it.

There is an exact time of the day when one should visit the cave to enjoy the play of lights to its fullest. Usually, that happens around midday when the sunlight reflects from the white sea bottom and generates spectacular shades of blue light coloring the water and seafloor silvery white. As the Blue cave Croatia is a small cave, at just 24 meters long, 15 meters high and not more than 12 meters deep, the experience of entering it with a small boat is really thrilling and unique. Just duck your head and enjoy the passage from a slightly chaotic open sea environment with lots of boats and tourists to a super calm world filled with relaxing colors.

Organized tours to the Blue Cave are available from the nearby Mezoporat cove, ensuring both access and safety for visitors. Embarking on this unforgettable journey, one can expect an approximately 40-minute expedition after departing from Mezoporat. The experience promises to be nothing short of extraordinary, allowing guests to immerse themselves in the enchanting allure of the Blue Cave’s captivating ambiance.

The history of the Blue Cave

In 1884, an Austrian artist named Baron Eugen Ransonnet unveiled a breathtaking wonder to the world—the Blue Cave located on the enchanting Biševo Island. This remarkable discovery sparked the dawn of tourism in the captivating region of Dalmatia, establishing the Blue Cave as an absolute must-see destination in the Adriatic Sea. Recognized as a geomorphological marvel of nature since 1951, this cave holds a mesmerizing natural light phenomenon that leaves visitors awe-struck.

Baron Ransonnet, in his writings, eloquently described how the cave’s luminous illumination bestowed a silvery-bluish hue upon the surrounding rocks, ores, and submerged objects, evoking a reminiscent charm akin to the renowned Capri Blue Grotto. Light permeates the rocky reef from every direction, casting an ethereal glow that transforms the cave into a majestic underwater fortress, fit for a deity of the sea. In 2019, a comprehensive geological survey of the cave shed further light on this captivating phenomenon.

The entrance area of the Blue Cave reveals a sandy expanse, imbued with a light-yellow hue. As the morning sun gracefully bathes this sandy floor, penetrating through the submerged entrance, an abundance of light reflects off the lighter-colored sand grains. This illuminates the cave’s interior, contrasting with the biogenic overgrowth that adorns the surrounding rocks. The spectacle is truly a sight to behold, casting a magical ambiance throughout the cave’s domain.

Aside from its submerged entrance, the Blue Cave boasts two additional access points—one by sea and the other by land. This semi-submerged sanctuary serves as a haven for numerous organisms that thrive amidst the partial darkness. Recent research conducted in 2019 unveiled an astounding discovery, identifying a total of 119 distinct marine species within the Blue Cave, five of which are strictly protected by law. The preservation of this ecological treasure is of utmost importance, necessitating visits to the cave to be conducted under the guidance and supervision of authorized concession-holders.

In conclusion, the Blue Cave stands as a timeless testament to nature’s artistic mastery and remains an emblematic destination that has captivated the hearts and imaginations of travelers since its discovery. As visitors venture into its depths, they are met with a luminescent spectacle that transcends the ordinary, offering a glimpse into an otherworldly realm beneath the sea. The Blue Cave continues to enthrall all who encounter its ethereal beauty, beckoning adventurers from far and wide to witness its mesmerizing allure firsthand.
