Boko Haram sparked global outrage when it seized more than 219 girls from Chibok town a year ago.
The US, China and other foreign powers promised to help find the girls.
The Nigerian woman, who lived under Boko Haram's rule in Gwoza, told the BBC she saw the girls
in Islamic attire, being escorted by the militants.
"They said they were Chibok girls kept in a big house," said the woman, who asked not to be identified for fear of reprisals.
"We just happened to be on the same road with them," she added.
Three other women also told the BBC they had seen the girls in Gwoza.
Another woman told the BBC she last saw some of the girls in November at a Boko Haram camp in Bita village, also in the north-east.
"About a week after they were brought to the camp, one of us peeked through a window and asked: 'Are you really the Chibok girls?' and they said: 'Yes'. We believed them and didn't ask them again," the woman said.
"They took Koranic lessons, cleaned their compound, cooked for themselves and they braided each others' hair. They were treated differently - their food [was] better and water clean. "
Boko Haram was believed to have turned Gwoza into its headquarters after it captured the town in August 2014. Nigeria’s military, backed by troops from neighbouring countries, recaptured the town last month.
The militants were suspected to have fled to the nearby Mandara Mountains, near the border with Cameroon. It is unclear whether the girls are with them there.
