Sierra Nevada to Invest 600,000 Euros to Prevent Overflows in Cauchiles Ravine

The ski resort will undertake works this summer to enhance safety on slopes and at the Mirlo Blanco recreational complex after damage from past storms.

The Sierra Nevada ski resort will invest over 600,000 euros this summer in the Cauchiles ravine to prevent future overflows that could affect the slopes and the Mirlo Blanco recreational complex.

This intervention, expected to last approximately four months, will focus on the lower part of the resort, specifically at the end of the Río slope and the adjacent path to the recreational area. The main goal is to reinforce safety and infrastructure following incidents that occurred in previous winters.
The works are a response to problems caused by intense rainfall, such as that recorded in February 2025 and a series of storms between late January and February 2026. These meteorological events rendered the pipeline, which channels water from the ravine to the Monachil river, unusable, leading to overflows onto the slopes, particularly affecting the Río slope and the Mirlo Blanco facilities.
With this project, the resort's management company aims to optimize the drainage system and increase the hydraulic capacity of the ravine, thereby minimizing the risk of future floods and material damage. The action will focus on the auxiliary or “bypass” system of the ravine, improving water evacuation and preventing erosion and sediment transport.

"The objective is for the works to better withstand extreme weather events, which are becoming increasingly frequent in Sierra Nevada in recent years."

In addition to protecting infrastructure, the project aims to enhance the safety of visitors and users of this recreational area, especially during periods of heavy rainfall or snowmelt. The work will be carried out under strict environmental protection guidelines, adhering to the regulations of the Sierra Nevada National Park and its protected natural environment.
The resort's management has emphasized to participating companies the need to keep the surrounding environment intact outside the work areas, avoiding spills, waste accumulation, or any unnecessary environmental impact. This initiative seeks to balance environmental protection with the improvement of essential infrastructure for the operation and safety of one of Granada's main tourist attractions.
