North Denes Airport (ICAO: EGSD) is a heliport that is located in the northern suburbs of Great Yarmouth, just off the A149 next to Yarmouth Stadium, formerly used as a base for services to the gas platforms in the southern North Sea. Fixed-wing aircraft were not permitted to use the heliport. The heliport was owned by CHC Helicopter, which operated several AgustaWestland AW139 helicopters.
