The South West Herts Great Big Green Week (GBGW) is nearly here.
Join us for this celebration of community action to tackle climate change and protect nature. Events will be taking place across Three Rivers and Watford between the 6 – 14 June– including the Watford Green Festival on the 7 June.
There are over 25 events during the week to choose from for all ages – from family fun days and fairs, walks and Zumba, to getting your hands dirty with conservation volunteering, repair cafes and events to help wildlife, plus litter picks, bike rides and so much more!

Each event in the week to view below contains a link to the events full details (which can also be found in south-west hert’s event pages).
