[ENG/ESP] Last geological trip of 2025 / Último viaje geológico de 2025
A Necessary Introduction

In the previous post, we talked about our trip to the Yumurí Valley, one of the most important natural areas in this province; today we'll discuss our stay in one of the most outstanding karst formations in Matanzas, a province located in western Cuba.
A province with many caves
For those of us who live in Cuba, especially in the western part of the country, or who have visited this province, it's well known that it's home to some of Cuba's most famous caves: the Bellamar Caves.
However, very few people know about the many other caves in the area, among which the Saturn Caves stand out.
Work Objectives
Our objective was to assess the importance of these caves for the region's tourism development, evaluate the conservation status of the site and the different species that inhabit it. We also needed to check the water quality and its potential uses for human enjoyment.
The Adventure
Unlike our previous trip, this time we had experience with the route, as we had to take part of the path used to reach the Yumurí Valley.
We crossed the Bacunayagua bridge again, which, as I mentioned in As mentioned in a previous post, this is the highest bridge in Cuba. Crossing this feat of Cuban civil engineering allows you to admire the region's great natural beauty, the vastness of the vegetation, and the wide variety of animal species that abound there.
Even though we've been to this place before, we're always moved by its natural beauty.
The Arrival
After a little over three hours, we arrived at our destination. I truly can't express all the emotion I felt at such beauty, but I also saw how mismanagement and improper use of the facilities have caused the place to lose its former splendor and fall into disrepair.
Saturn Cave is located very close to Varadero. This natural treasure is a karst cavity that houses a crystal-clear lake approximately 20 meters wide, 80 meters long, and 18 meters deep. Its turquoise waters, with their slightly cool temperature, are what make it stand out. According to local experts, its waters are home to blind fish, shrimp, and other unique species.
Upon arriving at the cave, we found ourselves in a karst paradise with diverse formations created by the action of wind, water, and weather, which look like they were painted by artists.
One of the distinguishing features of Saturn Cave is the great variety of stalactites and stalagmites. For those unfamiliar with the subject: stalactites and stalagmites are natural formations that form in caves as a result of the continuous deposition of minerals by seeping water.

Stalactites are the formations that hang from the ceiling of a cave, while stalagmites rise from the floor to the ceiling. When these two types of rock join, they form beautiful columns of karst rock.
