The 24-year-old, who won a silver medal in the 200m breaststroke at the 2012 Games, visited Scotstoun Leisure Centre as part of a British Swimming event aimed at encouraging more children to take up the sport.
More than a dozen athletes from Team GB were in Glasgow to promote swimming, diving, water polo and synchronised swimming.
During the visit Michael also met Glasgow City Council leader Gordon Matheson and his former school mates from Glasgow School Of Sport, Bellahouston.
The swimmer, now based in Somerset, where he attends Bath University, said he hoped to win a gold medal in his home city when it hosts the 2014 Commonwealth Games.
He said: "London 2012 was an amazing experience with huge crowds, and if we as Olympians can inspire more children to get in the pool as part of the legacy of the Games that will be incredible.
"It's great to be involved with the Heroes Tour and I hope all the kids taking part across the country have a fantastic time.
"I hope they will continue in the sport and some may even be lucky enough to experience an Olympics or Paralympics."
His Team GB swimming teammates Craig Benson and Ross Davenport were also at the event.
Mr Matheson said: "Michael was one the stars of Team GB at the Olympic Games, where he confirmed his place as one of the world's top swimmers.
"To land a silver medal and set a new British record showed just what he is capable of and bodes well for the 2014 Commonwealth Games.
"He is a real inspiration and we are all very proud of him, none more so than the staff and pupils at Glasgow School Of Sport, where he was a pupil for six years."
Ashley Howard, chief executive of Scottish Swimming, said: "We are delighted that athletes from across our sport are going to be part of this tour.
"Their inspirational stories will help us to achieve our Olympic and Paralympics legacy to increase participation."
Meanwhile, four groups of Scouts today climbed to the top of the UK's highest peaks to prepare the flame that will light the Paralympic Torch.
On the day that the first athletes began arriving in London for next week's opening of the Paralympic Games, the Scouts set off at dawn to reach the summits of Ben Nevis, the UK's highest peak, as well as Scafell Pike, England's highest mountain, Slieve Donard in Northern Ireland, and Snowdon in Wales.
Once at the top, they were going to use a metal rod and strike it against a rough steel surface to make the sparks that will ignite the flame.
The flame will then be placed in a miner's lantern and brought back down on foot before being transferred to each country's capital for a day of Paralympic celebration.
