If you ride to the top of the Hotond, you might end up with a purple-blue complexion from all that pushing on the pedals. But you can see the real purple-blue in the spring. Then the wild hyacinth blooms and the woods colour spectacularly purple-blue. Also worth seeing: lily-of-the-valley, buckler-fern and wild honeysuckle.
Do you prefer to remain in the valleys? Keep your eyes peeled for the golden-ringed dragonfly, the fire salamander, the blind worm – also known as the slow worm – and the silver-washed fritillary butterfly.
