Totternhoe Knolls Nature Reserve sits within an important medieval quarrying area; the resulting spoil tips are now home to a prolific range of wildflowers and butterflies, best seen during spring/summer months. There are some hill climbs, making this one of the more challenging walks, but you will be rewarded by panoramic views over the surrounding countryside.
