A memorial service was held at a monument in Derry's Bogside on Sunday and afterwards some families took part in a march.
Around 3,000 people took part in the parade, which retraced the route taken by civil rights marchers on 30 January 1972, where British paratroopers killed 14 people.
The Saville Report, published in 2010, declared all the victims to be innocent and Prime Minister David Cameron apologised in the House of Commons.
At the time, most of the families decided to end the annual march they had taken part in for 39 years, saying they had been vindicated by Saville's findings.
However some families who are pressing for the prosecution of the soldiers involved, said they would continue to march.
Kate and Linda Nash's brother William was one of those killed on Bloody Sunday.
Kate Nash said the march should remain an annual event to help lobby for other bereaved families seeking justice.
"I am delighted with the turnout," she said.
"But even if it had just been myself and my sister, we would still have a right to march. That is democracy.
"We are going to continue to march for prosecutions, but beyond that, this is a unique march and it should continue for all those who are seeking justice.
