We've been able to make the upgrades thanks to Monmouthshire County Council’s access improvement scheme funded by the UK Government’s shared prosperity fund.
The works are part of the community-led celebrations for this year's 225th anniversary of the canal with construction of the waterway starting near Gilwern in 1796.
David Morgan, development manager for Wales at Glandŵr Cymru, said: "As a charity, we want to make sure that everyone can enjoy our canals, and the improvements to the pathways and picnic site at Gilwern will enable all canal lovers to reap the benefits of spending time by water.
"We’re grateful to Monmouthshire County Council for their support of this project, and of our Brecon 225 anniversary celebrations, which will see us mark this special anniversary for the northern section of the Monmouthshire & Brecon Canal throughout the year with a series of community events.
"Our colleagues and volunteers do a wonderful job in making the canal a fantastic place to be. Their hard work to upgrade this site will offer people a place to relax and enjoy being next to the canal."
