The 105 girls, covered head to toe in burkas, arrived aboard five buses in the town of Dapchi, in Yobe state, where they were greeted by their parents at the boarding school from where they were snatched on February 19.
After their release on Wednesday they had spent three days in the national capital Abuja and were greeted by President Muhammadu Buhari.
Kachalla Bukar, the father of one of the girls who is spokesman for the parents, said they were flown to the major northern city of Maiduguri from Abuja, then transferred under military escort to Dapchi.

Schoolgirls abducted by Boko Haram 'brought back': parents
Top officials were on hand for a solemn ceremony in which the parents regained custody of their children.
"My joy knows no bounds," Mai Saleh Gaji told AFP after being reunited with both his daughter and his grand-daughter. "The nightmare of the kidnap will not deter me from sending them to school," he added.
But for Ali Gashomu, the kidnap of his daughter just hours after she was enrolled at the school for the first time had left him "traumatised and terrified" and undecided about whether she should return.
Information Minister Lai Mohammed said the girls were released following negotiations with the insurgents and that no ransom payment or prisoner swap was carried out.
"All they demanded was a ceasefire that would open a safe corridor for returning the girls," he said Sunday, adding that the week-long truce began on March 19.
The girls were among 111 seized last month, of whom five died apparently during the violent hostage-taking or in the trucks that took them away.

Held on Lake Chad island
Their release leaves one schoolgirl, Leah Sharibu, still in the hands of the kidnappers, reportedly because she is a Christian who has refused to convert to Islam.
Buhari on Friday pledged to do "everything in our power" to obtain Leah's freedom.
Authorities earlier expressed optimism that she would be released at the weekend.
But on Sunday, a spokesman for the national police said that comments by national police chief Ibrahim Idris had been "misunderstood and misquoted".
The police "reiterates that it has no information yet on the release of the last Dapchi schoolgirl," he said.
According to witnesses contacted by AFP, the girls were held on an island on Lake Chad, which is a known stronghold for fighters loyal to Boko Haram factional leader Abu Mus'ab al-Barnawi.
The Dapchi kidnapping revived painful memories in Nigeria of the April 2014 abduction of over 200 schoolgirls from Chibok, a town also in the northeast, which caused global outrage.
While some of the Chibok girls have been freed in exchange for ransom and the release of top Boko Haram commanders, a total of 112 remain in captivity.
Boko Haram -- which means "Western education is forbidden" in Islam -- has repeatedly targeted schools providing Western education in the mainly Muslim region as part of an insurgency that has killed at least 20,000 people and displaced more than 2.6 million since 2009.
While a 2015 offensive launched by Buhari successfully reclaimed swathes of territory back from the jihadists in Nigeria, the group still stages deadly attacks on both military targets and civilians.
