About the event

After the success of the first Hertfordshire Chalk Stream Challenge route the River Mimram in 2025, we are launching a new route on the River Beane.

Join us at Waterford Marsh to learn more about why chalk streams are so special, and why we are lucky to have so many in Hertfordshire. Use our spotting sheets to find out more about the plants and animals that live around the river.

We will have our river dipping kit out to show you the creatures that live under the water.

There are 2 sessions available and we kindly ask you to book a session before the event, so we can better manage numbers. This a self led activity but our river team will be there to guide you. You can arrive at any time in your in your session but please allow at least 1hour to explore the site.

The route starts at the gate entrance to Waterford Marsh, Vicarage Ln, Waterford, Hertford SG14 2QA

This event is suitable for children of all ages and well behaved dogs.

What is the Chalk Stream Challenge

The Chalk Stream Challenge is about exploring your local chalk stream, understanding what makes them so rare and important, whilst discovering their incredible wildlife and rich heritage.

You can then download your certificate to display with pride and you can even purchase one of the Chalk Stream Challenge badges.
