The volunteers joined our staff on the towpath off Iver Lane, helping to clear over-grown vegetation and rubbish from a half-mile stretch of the canal.
The group regularly volunteers as part of the Trust's Towpath Taskforce team, which encourages people out onto the waterways to help improve them.
Debbie Vidler, Canal & River Trust volunteer development co-ordinator, said: “We're really grateful to the volunteers for their hard work, they've improved this stretch no end. It just shows how much we can enhance the canal with a bit of extra help and it's always amazing to see people giving up their time.
"The Grand Union Canal is going from strength to strength at the moment, we're always on the lookout for more people to help, so do get in touch if you are interested.”
Tony O'Dell, one of the volunteers who took part in the clean-up, said: “The day was really enjoyable. All of us are regulars and we get on really well with the boat crew. Boaters will definitely notice the difference now that they have an unrestricted view when approaching Iver Road bridge tunnel.”
