A search will resume this morning in far north Queensland for the pilot of a helicopter that has crashed into seas off Cape Tribulation.

Police said the privately chartered helicopter was travelling from Cooktown to Port Douglas when it ditched about 1 kilometre from Noah's Beach.

Local resident Miika said it happened just south of the Cape Tribulation camping grounds about 8:00pm.

"A helicopter hit the water. There is one person alive safe and sound, but there is one person missing, probably in the water," Miika said.

Emergency services have confirmed there were two men onboard.

A 43-year old passenger made it to shore, found people camping nearby, and used their mobile phone to call police.

Police were at the scene and at least one rescue helicopter was out searching the seas and beaches for the missing pilot.
