It's happening on Sunday, September 24 (10am - 2pm), near the banks of the Gaywood River.

The event, hosted by partners of the Hidden Heritage of the Gaywood River project is based around the 12th King's Lynn Scout Hut, in Beulah Street.

Activities including tales of the river bank storytelling, mini guided walks around Salters Sanctuary and Gaywood River, pot decorating and acorn planting, wildlife quizzes, nature and wildlife-inspired crafts, and making fish out of reeds.

There will also be a mobile fish tank and a pond-dipping tank that species that are likely to be found in the Gaywood River can be seen close up. Families can also go on a bug hunt or build a bug hotel and learn all about the lifecycle of bugs and frogs.

King's Lynn District Society of Model Engineers are also offering rides on the miniature railway - a small charge applies to this activity.

Alistair Beales, West Norfolk council's cabinet member for Special Projects and Assets, said: 'This is a great opportunity to find out more about the history of the Gaywood River and the importance of the chalk stream, and to learn about the species of bugs and wildlife that live in and around the area .

'It will be a hands on demonstration of the sorts of activities that people will be able to do, once the Hidden Heritage of the Gaywood River project is completed.

'In future there will be pond-dipping platforms, some of the river banks will be cleared and access to the former landraise site will be improved for wheelchairs. The area will be planted with wildflowers as well as maintaining areas of woodland.'

A £210,000 scheme to create wooded parkland and wildflower meadows along the Gaywood River near Lynnsport was announced last month.

There will also be a new disabled access footpath through the site, a pond dipping platform and benches.

Part of the river - originally a chalkstream - will be restored to its original habitat.

As well as open areas, the reserve includes Salter's Sanctuary, a thicket of blackthorn with a tunnel through the undergrowth.

The work is being part-funded by a £94,000 lottery grant.
