Essa gruta azul fica em Capri! Amamos muito a experiência! Pagamos 18 euros e chegamos lá de barco! No final eles sempre pedem gorjeta e leve seu dinheiro trocado pois eles não dão troco e no cartão cobra uma taxa extra! Tem bastante fila e esperamos quase 30 minutos para entrar mas valeu a pena E aí? Teria coragem? #viagem #italia #capri #grutaazul

"Gruta do Lago Azul - Beautiful, Safe, and Worth Experiencing.

Gruta do Lago Azul is a stunning natural site, the deep blue water and dramatic cave formations are definitely worth seeing. While it wasn’t the highlight of my trip to Bonito, I’m really glad I got to experience it.The tour is quite structured and short, with allot of stairs involved, so it may feel a bit underwhelming if you’re looking for something more adventurous.

That said, the guides were fantastic—knowledgeable, friendly, and made sure everything was safe and well-organized. It’s a unique and peaceful spot, and definitely a worthwhile stop if you’re exploring the area.
Book ahead from my experience."

"It is quite beautiful but if you have been in a cave before it is not so special. You walk down, get some info and up again. 30 min and you are ready. The price was not in balance with the experience for me"

martijn plas

"The place is very beautiful. It is a huge stalactite cave with unusually blue water. The tour is not accessible and is not in English, the guide completely ignored our presence and was not very nice. The attraction is boring. Go down the stairs to see the beauty and go back up. Not sure it is worth the price."

In-depth insights and expert knowledge

The Geology of Blue Lake Cave

Blue Lake Cave is a remarkable example of a karst landscape, formed by the dissolution of soluble rocks like limestone over thousands of years. The cave's defining feature, the luminous blue lake, owes its color to the purity of the water and the way it reflects and refracts sunlight. The water is exceptionally clear, with minimal sediment, allowing light to penetrate deeply and interact with the minerals present, creating the striking azure hue. This clarity is a testament to the natural filtration processes occurring within the surrounding geological formations. Reddit

Within the cave, visitors can observe a variety of speleothems, including stalactites (hanging from the ceiling) and stalagmites (rising from the floor). These formations are created by the slow drip of mineral-rich water, which deposits calcium carbonate over vast periods. The sheer size and intricate details of these natural sculptures are a highlight for many visitors, showcasing the slow, persistent power of geological processes. The guided tours aim to educate visitors about these fascinating natural phenomena. Reddit

Understanding the Tour Experience

The visit to Blue Lake Cave is a structured, timed tour designed for efficient visitor management. Upon arrival, you'll join a group led by a guide who will escort you through the cave. The path involves navigating a considerable number of stairs, both for descent and ascent, which is a key consideration for visitors. Guides are generally knowledgeable about the cave's geology and history, though communication can be a challenge for non-Portuguese speakers, as tours are primarily conducted in Portuguese. Reddit

While the cave is undeniably beautiful, some visitors find the tour to be quite short, lasting only about 30 minutes. This brevity, combined with the structured nature of the visit, can lead some to feel it's less of an 'adventure' and more of an observational experience. Managing expectations is key; it's a chance to witness a unique natural wonder rather than an immersive exploration. The guides are focused on safety and ensuring the preservation of the cave environment. Reddit
