Local famous faces including television presenter Tim Lovejoy and actress Bonnie Langford showed their support during the march on Saturday (March 18) in Chiswick.
More than 100 people took part in the demonstration against proposed cuts to youth services in the borough, affecting three youth centres.
It was the second march down Chiswick High Road from around 10am before moving on to Hounslow High Street in the afternoon.
Campaigner Sarah Harvey said: "Children, parents and members of the community come out and marched down Chiswick High Road making as much noise and bringing as much attention to the cause as we possibly could.
"Some of us went on to join dozens more at a march in Hounslow and marched down Hounslow High Street."
The first protest held last month saw around 100 people chant "no cuts" and "save our youth centres" outside Hounslow Civic Centre.
A public consultation was launched by Hounslow council after plans were announced to cut the budget for youth services by £212,000.
The changes proposed five youth service projects affecting vulnerable young people's groups will remain, while three youth centres face closure.
More than 700 people have now signed an online petition to save youth services and stop the cuts.
The petition will close on March 31.
