30 Day Map Challenge


Welcome to our #30DayMapChallenge gallery! The 30 Day Map Challenge is a global month of mapping. Anyone can take part! Participants create one map a day for 30 days — each based on a different theme — and share them on social media using the hashtag #30DayMapChallenge.

Every map is a mystery map until the day arrives (no spoilers!). Click a picture below to view the map, how it fits the theme for that day, and how it was made. Note that some of our maps are on external websites. Check back throughout November to see a new map each day!

Warning! Some of our maps are serious, some are silly, some are scientific, some anything but! We have followed the 2026 themes for a map on each day during November. But we also have a mission - all the maps here relate to wildlife and Gloucestershire Wildlife Trust's vision for our county: more wildlife, more wild places and more people with a connection to the natural world.

Subscribe to Gloucestershire Wildlife Trust's e-newsletter here if you'd like to keep up to date with our current events, activities and projects.



2nd November - Day 2: Lines


  !Map links will only work when the day arrives! Most of the links will open in a new window and some will lead to an external website
