The youngsters from St Columba’s and Rockfield primaries will be walking the path on Monday (November 29), leaving school at 11am.
They will walk the 700m route between Glengallan Road and Glenshellach Road, where a plaque acknowledging the project’s funders will be unveiled.
The £40,000 project – which took four weeks to complete - involved resurfacing, improving drainage, removing a narrow bridge and replacing it with a culvert and removing steps and replacing them with a ramp.
Funding was provided by Argyll and Bute Council, Sustrans and Highlands and Islands Enterprise.
Chair of the Oban, Lorn and the Isles area committee, Councillor Duncan MacIntyre, said: “This is a well-used route, particularly to the primary campus, and the upgrade will make it a much easier journey for those who regularly use it.
“The route is now safer, smoother and dryer and is suitable not just for cycles but also buggies and wheelchairs. I am delighted it has been completed, and would encourage people to go and see for themselves the difference the improvements have made.”
