The word 'Halbinsel' (peninsula) is often part of geographic proper names. In these cases, it usually comes after the actual name.

Halbinsel vs Insel
island
'die Insel' and 'die Halbinsel' both describe land near water. The difference is simple but important: an island is completely surrounded by water. A peninsula is surrounded by water on only three sides and remains connected to the mainland on one side. The words can be confused because both can look like separate pieces of land in the water. If you cannot reach the mainland at all without a bridge or boat, it is an island. If there is still a natural land connection, it is a peninsula.
Halbinsel
Die Halbinsel ragt weit ins Meer, ist aber im Norden mit dem Festland verbunden.
The peninsula extends far into the sea, but it is connected to the mainland in the north.
Insel
Im Sommer fahren wir mit der Fähre auf eine kleine Insel.
In the summer, we take the ferry to a small island.
