The volunteers painted lock beams, built bug hotels and resurfaced a path at the World Heritage site, getting the popular attraction spruced up and ready for the summer season.
Steve Manzi, volunteer development co-ordinator at the Canal & River Trust, said: “We're really grateful to have the help of the volunteers from Burges Salmon to get Caen Hill looking great for the summer. In one day they managed to make a huge difference, and hopefully enjoyed being out by the canal as well.
“We'd love to hear from you if you're interested in getting involved in volunteering on the waterways. There's always lots to do – from getting your hands dirty to being a friendly face for the many visitors we have to the Kennet & Avon Canal."
