G! Festival takes place in the small town of Syðrugøta, which is in the Eysturoy region of the Faroe Islands. Halfway between Norway and Iceland, these islands are part of Denmark.
Yes, there is a campground located on Mortansbøður in Norðagöta. To gain access you need a tenting-area wristband as well as a weekend or single-day wristband.
Shuttle busses will be available to drive festival-goers from the campground to the festival site and back. These require a wristband that can be purchased at the festival site or on the busses themselves.
