The first guided walk informing people about the rivers environmental pressures is taking place this Sunday and it will run from Reffley Wood to Great Ouse.
The river Gaywood is a spring-fed chalk river, a rare and declining habitat, and participants will find out what can be done to help its natural functioning.
The walk is run by Norfolk Rivers Trust and the response has been overwhelming with all the pre-booked places being taken.
Gemma Clark, community involvement officer said: “The walk aims to tell people about the much overlooked river and it’s relationship to the town,the importance of its wildlife and the work of the Norfolk Rivers Trust.”
The river provides a vital wildlife corridor which links green spaces and brings wildlife into the heart of Lynn.
It is hoped that exciting animals, birds, insects and fish will be spotted en route.
The walk will finish at Millfleet, where man’s historical use of the river will be brought to life by the expert guide.
After the 4.5 mile walk has finished coffee and cake will be enjoyed by walkers at the Marriott’s Warehouse.
