Gibraltar has a land border with Spain.
Spain has three land borders - to the north with France, and to the west with Portugal. The mountains which form the border with France are the Pyrennees. There are several mountain ranges which run mainly north-east to south-west across the Iberian peninsula, but none of them are specifically borders between Spain and Portugal. There is also a small land-border between Spain and the British colony of Gibraltar, but it is not mountainous.

Usually in boats. A strait is a narrow water passage between two points of land, as in the Strait of Gibraltar at the entrance to the Mediterranean Sea.
Spain has bodies of water surrounding it which are the north Atlantic ocean, the Mediterranean sea, and the bay of Biscay. Spain also has land borders with Portugal, France, Andorra, the UK, and Morocco.
