Join Thames 21 with Chris McGaw and Matthew Blumler as we launch the Waterway Treasure Hunt in Lewisham. Get into the river for this wade to explore the wealth of wildlife one of the Thames’ urban tributaries can hold. You’ll be able to celebrate all that you find on the new online map. This engaging event is a great way to learn more about the area and get involved in a new interactive project. Thames21 will provide boots, size 3 and up.
