The guppy zone defines where I can find and leave a guppy. In other words, these are the areas where I can start and end the rental of a vehicle. In addition, within the guppy zone there is no blue zone parking fee.
In the guppy app you will easily identify the guppy zone because it is highlighted in light blue. This covers most of the urban area of Santander and other areas of interest such as El Sardinero, the Palacio de la Magdalena or the Camello beach.
