Malala was accompanied by her father Ziauddin Yousafzai, family members and State Information Minister Marriyum Aurangzeb among others as she travelled from Islamabad to Swat via helicopter after a security clearance was issued.
It had been uncertain whether Yousafzai would be able to visit Swat, parts of which spent almost two years under the Pakistani Taliban militants' harsh interpretation of Islamic law, due to continued concerns for her safety.
In rural areas where millions of girls leave their schools to get married and take care of their homes and children, it means that Malala is not just fighting the decade's old traditions of a society, but also challenging the powerful Mulla's who have complete dominance in the society. "And it was never true, ' she stated in between sobs of happiness", at the press conference at the Prime Minister's residence here.
In a letter, written by Adnan Rashid, the Taliban militant, claiming the attack on Malala Yousafzai in 2012, it was highlighted that the attack on Malala was because of her belief that "pen is mightier than the gun".
Yousafzai has won praise from across Pakistan on her return home, but some critics on social media have tried to undermine her efforts to promote girls' education.
She suffered bullet injuries and was admitted to the military hospital Peshawar but was later flown to London for further treatment.
"I still can't believe I am here", she said.
"Some students are transported by the school, an initiative paid for, along with the books, uniforms, tuition for the orphans and poorer students, teacher salaries and the building itself, by the Malala Fund", said Sajid Shah, the principal of the school.
There had been much speculation within the country over whether Malala would go to Swat during her visit.
In October 2012, Yousafzai was shot in the head by a Taliban assassin who had jumped inside her school van and yelled, "Who is Malala?".
The Taliban, expelled from valley by Army in 2009, accused her of vehicular "Western propaganda" and chose to assassinate her.
"Peace has returned to Swat because of the invaluable sacrifices rendered by my brothers and sisters", she said at a school outside Mingora, the district's main town, where she was escorted by the Pakistani military.
That was the year she was attacked by the Taliban for advocating girls' education.
"What I want is for people to support my goal of education and think about the daughters of Pakistan who need an education", she told Pakistan's The News in comments published on Saturday. She (Malala) said "I'm so emotional, words can't express what I'm feeling right now". Don't think about me.
Not everyone in Swat, though, has such reverence for Yousafzai, who became the youngest Nobel laureate in history in 2014 at age 17.
"Malala should come back again and again".
In response to a question about her role models, Malala said the nation had just lost one of the best role models, Asma Jahangir. I could not control it, ' she told the gathering.
