The music event, part of the Surf and Skate Festival, will be held at Blackbutt Forest on December 14.

To kick-start the festival into its first year The Beautiful Girls will be headlining with their roots and folk-inflected pop, alongside three-piece, indie-rock royalty The Grates.

Triple J unearthed winners Moaning Lisa will also perform as well as Erthlings, Benny Walker, Pacific Avenue and Lemon Row.

The event has partnered with Illawarra locals Five Barrel Brewing and Simall Wines to offer event-goers craft beverages.

The event will also have hand-crafted market stalls and food trucks.

There is a free valet bike parking service, or event-goers can park in the designated car park with a shuttle ferrying people to the festival grounds.

The music event rounds off the Shellharbour Surf and Skate Festival which runs from December 7 to 15.

The Mercury has two double passes to give away to the Hidden Forest Festival. Go to our Facebook page to enter. The giveaway closes on November 27 at 2pm.
