The Pyrenees.
The Iberian Penisula is part of Europe but separated from the bulk of Europe by the Pyrenees Mountains.
Nothing separates a mountain range from land, the mountain range itself is what separates. For example, the Pyrenees separate France, Spain, and Andorra from each other as it is the border. However, nothing separates the Pyrenees from the rest of Europe.
Spain is in Europe, so there is no mountain range that divides Spain from Europe. What you are referring to is the Pyrenees Mountains, which forms much of Spain's border with France. As Spain is in the southeast of Europe, it could be looked upon as a boundary between Spain and most of the rest of Europe.
The Iberian Peninsula is located in southwestern Europe, separated from the rest of the continent by the Pyrenees mountain range. It is occupied by the countries of Spain and Portugal, and includes the microstate of Andorra.
