Yera Station is an old railway station located in the municipality of Vega de Pas, Cantabria. It was part of the Santander-Mediterranean railway project, which was never completed. The station is abandoned and is located near the northern mouth of the Engaña Tunnel. In 2022, the Government of Cantabria approved a rehabilitation project to convert the station into a hostel, exhibition hall and restaurant, with the aim of promoting sustainable tourism in the area. This project also includes the creation of a cycle and pedestrian path to the tunnel.

The spa is located in Las Caldas de Besaya, which belongs to Los Corrales de Buelna, and this name is thanks to the spring of thermal waters that flows nearby, already known since Roman times (warm waters). On November 15, 1753, the old "Wool Road" or "Flour Road" that ran through this point and along the Besaya, achieved the rank of "Royal Road", notably improving the transport conditions of Castilian products destined for our coastal ports, for export overseas. The building is located next to the train stop across the old donkey-back bridge. Years later, the main road passed by, and all of this contributed to facilitating the communications of the Spa, although currently they are all out of use, but this has not caused the number of travelers to decrease and they remain very popular. The spa was built in the mid-19th century next to the hotel, the inn, and the casino, which was formerly an annex building. Today it is restored, being considered the oldest in the region and continues to receive those who wish to benefit from its mineral-medicinal waters.
