The Golan (its official name is the Syrian occupied Golan) is Syrian territory, populated by Syrian Druzes. It has been occupied by Israel since 1967, after Tsahal defeated the Syrian army. It will be given back to Syria the day when a peace treaty is signed.
There's absolutely no reason to worry about traveling to either Israel, the Golan or the Palestinian territory these days. It's extremely safe. The Golan is gorgeous, you will definitely enjoy the landscape, the hikes and the wine.
