At least 16 people have been killed and 27 injured after a bus carrying tourists in Bulgaria flipped off a highway and plunged at least 20 metres down a side road below.

Local police say the bus was travelling towards a nearby resort when the accident occurred in Svoge, about 20km north of the nation's capital Sofia.

It's understood the bus also collided with four cars, but it's believed none of the passengers in those vehicles were injured.

Bulgaria's Health Minister Kiril Ananiev said the crash was "extremely heavy" with "many, many victims."

Nikolay Gabrovski, Director of Neurosurgery Department at Pirogov Emergency Hospital, where many of the injured were transported, said some of the patients remain serious -- with injuries ranging from limb, chest and abdominal trauma.

"I expect we'll need at least another 24 hours until we have more detailed information about their condition, at the moment everything is literally changing minute by minute," Gabrovski said.

The mayor of Bozhurishte in the Sofia province, believed to be the hometown of most of the victims, said it was a horrible tragedy for the town.

"The victims are our relatives and friends," Georgi Dimov said.

"We also all know the bus driver, he is one of us and a local... He is a hard working person."

The Bulgarian government has declared Monday a national day of mourning for the victims.
