The Blue Lagoon is a very important site for Dragonflies and Butterflies. However, the owners, MK Council, have not carried out regular maintenance for several years. This walk will look at what state the key natural history parts of the site are now in.

This walk is not on made-up paths like previous walks so please wear suitable footwear.
