Mare Fen

Ancient peat diggings from medieval times stretch across this wetland expanse just outside Cambridge, creating a landscape that looks more Norfolk Broads than East Anglian fenland. Mare Fen is one of those places that rewards the curious - shallow pools reflect the enormous sky while reed beds rustle with hidden wildlife.

Birdwatchers will have a field day here. The mix of open water and marshy ground attracts everything from kingfishers darting between the willows to marsh harriers quartering overhead. Early morning visits are particularly rewarding when the mist lifts and herons stand motionless in the shallows.

Walking here isn't challenging - the paths are mostly level boardwalks and raised tracks - but waterproof boots are essential after rain. Families with older children who don't mind a proper countryside walk will enjoy spotting dragonflies and learning about this recovering landscape. Toddlers might find it a bit much.

From nearby holiday parks like Crystal Lakes Leisure or Roseberry Tourist Park, it's an easy drive for a morning exploration. The area works well as part of a wider Cambridge visit - you could easily combine it with the city's colleges or Wicken Fen for a full day of contrasts. Just don't expect facilities here; bring everything you need and respect this working conservation site.
