The Merlino’s Cave Tour it’s a unique “adventurous visit” in this area. Imagine yourself facing the coastal panorama of Baia of Triest standing in front of the cave entrance. The adventure starts here! Guided by professional and certified speleologists you will descend down the coast into the Merlino’s Cave wearing the outfit and gears of a real speleologist! Enjoy your first descent down ropes (a couple of meters) and then be ready to start your hike/visit in the natural beauty and historical cave.

Into the Merlino’s Cave, our guides will tell you interesting facts about it and show you some really nice manmade architecture that seems to melt with it. The Cave is large and has no narrow paths. Temperatures inside are about 13°C – 15°C.

The journey inside the “Y shape” of Merlino’s Cave will lead you to his exit climbing up to a big sand hill (like a desert dune, but inside the cave)! Cap Lights off and you find yourself just outside the town of Aurisina.

Must do experience, even if its just once! Great dirty time…


Went on a cave adventure on Saturday, we had the time our our lives, my legs are still stiff (3 days later) from that climbing, what a blast! I would recommend this to anyone


I would do this again and again. Getting into the cave…Oh my God….what an experience….


Thanks to the team, very professional, enthusiastic, knowledgeable and put safety ahead of all. It was a privilege to discover and share this underground world
