Gunnarsholt Airport (ICAO: BIGH) is a small general aviation airfield located in the Gunnarsholt area of South Iceland, situated in the Rangárþing ytra municipality. The airfield serves the surrounding agricultural and rural region, which is also known for reforestation and land reclamation efforts managed by the Soil Conservation Service of Iceland. The airport is a basic facility primarily used for light aircraft operations, agricultural flights, and occasional charter or private aviation. It does not serve scheduled commercial airline traffic and lacks the infrastructure typical of larger Icelandic airports.
