Tadnoll Heath

Important heathland site near Wool

Tadnoll HeathA site with a variety of habitats, but important mainly for its heathland, which the Dorset Wildlife Trust is managing traditionally: the heather in full flower is a glorious wash of purple and buzzing with bees.

The main footpaths are generally easy going, and the walk to the top of the Barrow is worth it for the views, though if you go down the other side, take care.
