A total of 12 students from the Get Ready for Work programme are carrying out work on the Forth and Clyde Canal next to The Boathouse Restaurant, in Kilsyth, as part of a Green Action project.
The 14-week voluntary opportunity is provided by The Scottish Waterways Trust and partner organisation, The Conservation Volunteers.
The young people, aged between 16 and 18, are volunteering every Friday and getting involved in joinery, painting and landscape work.
They recently took part in an activity to carve letters into stone to spell out Auchinstarry, which has been installed as part of a pond feature at the site.
Robert Canevy, from Cumbernauld, is one of the students taking part.
He said: "The Green Action project has been a great chance for me to do something different and learn new skills which will benefit me.
"I enjoyed taking part in the stone carving as it was really fun and it's nice to know that my work will be admired by visitors to the area for years to come."
Cumbernauld College has worked with The Scottish Waterways Trust for the past two years.
Stephen McKnight, senior learning assistant at Cumbernauld College, added: "The project has given the students a chance to build on the employability training we provide."
