The No. 7 trail starts at the former funicular railway station. To reach the station first pass the barrier on the internal lane that leads to the forecourt of the Grand Hotel.. Together with the former Panoramico restaurant, the station is part of a group of Art Nouveau buildings that made up the Campo dei Fiori Grand Hotel complex. Nearby, in the park opposite the Grand Hotel, we find the Marelli Grotto, a karstic cave that is one of the most significant of the many found on Mount Campo dei Fiori.
