More than 300 excited youngsters left Kelvin Way to head to Troon yesterday.
Crowds of people lined the streets and waved as the convoy of specially decorated cabs travelled through Glasgow city centre cabs before heading for the coast.
The youngsters were driven by more than 150 taxi drivers, who volunteered their time. Many of the drivers wore fancy dress, despite the hot weather.
Taxi driver, Jim Hennigan, has taken part in eight previous outings.
Dressed as CBeebies star Mr Tumble, he said he looks forward to the trip every year.
He said: "All the kids and teachers get excited, and the taxis are all done up. It's a good feeling."
Newly appointed Celtic manager Ronny Deila helped get the event started as he posed for pictures with the children and donated £7000 on behalf of the club.
The Scottish Premiership champions have supported the event for the past 16 years and during that time have raised £121,000 for the ride.
The Norwegian also helped pick the winners of the best decorated cab competition.
