This short route follows a section of railway that was taken out of service in June 2008. This was one more improvement of a line that was put into service in that area (from Alicante to Altea) on October 28, 1914, taking almost another year to complete the rest of the line to Denia. This completed a very long project that began in 1864, when an Iberian-gauge railway was designed. There were many ideas and twists and turns for a coastal line, which, starting in Altea, crossed extremely rugged  terrain that required a remarkable work of construction of tunnels, viaducts and sections hanging above the ravine.

A line that was finally made in metric gauge, which sought to connect in Denia with another railway of equal gauge, the line from Carcaixent to Denia, weaving a continuous railway corridor along the Alicante and Valencia coast. Our line was operated from its origins by the Compañía de los Ferrocarriles Estratégicos y Secundaria de Alicante (ESA), a company that maintained the service until August 1964. That year it was acquired by the public-sector Explotación de Ferrocarriles por el Estado (EFE), combining its services with the Carcaixent line, which had been operated by EFE for some time. This company was transformed into FEVE in 1965, a state entity that operated the line until December 1986, when it was transferred to the regional company FGV.

Under this brand, the line has been transformed, especially in its Benidorm-Alicante section, with continuous improvements as a tramway in its metropolitan sections and a commuter train in the section to Benidorm. Within this framework of improvements, in June 2008 a section was put into service at the entrance to Benidorm that eliminated a short very winding sector, which is now the basis of our greenway.
