The IRAM cycling route begins in the historic city of Granada, offering an exhilarating ascent to the IRAM observatory in the Sierra Nevada. IRAM stands for Institut de radioastronomie millimétrique. This challenging climb, to the second highest paved col in Europe, is perfect for cyclists seeking a demanding ride with the reward of stunning alpine views and a visit to a world-class astronomical facility. While you are there, tackle Europe’s highest paved col too; Pico de Veleta.

Starting in Granada, the route covers approximately 30 kilometers with an average gradient of 6.5%. The climb is characterized by a steady incline, with sections that become particularly steep as cyclists approach the higher altitudes. The journey from the urban landscape of Granada quickly transitions to the rugged beauty of the Sierra Nevada, offering a diverse and picturesque ride.

As cyclists ascend, they pass through a variety of environments, from olive groves and traditional Andalusian villages to the alpine landscapes of the Sierra Nevada. The air becomes cooler and the vegetation sparser as the elevation increases, providing a distinct contrast to the warmer, lower regions.

The IRAM observatory, situated at a high altitude, is a notable destination for its contributions to millimeter astronomy. The facility’s large radio antennas are designed to study the cold universe, offering insights into the structure of galaxies and the formation of stars. Reaching the observatory marks the culmination of the challenging ascent, where cyclists can take in panoramic views of the surrounding mountains and valleys.

The descent back to Granada offers a thrilling ride, with the expansive views and the winding road providing an exciting conclusion to the climb. The IRAM cycling route not only challenges riders with its elevation gain but also offers a unique opportunity to experience the natural and scientific wonders of the Sierra Nevada.
