This walk is the first day of British Summer Time - remember the clocks have gone forward an hour. Meet at Whipsnade Tree Cathedral Cark Park near Whipsnade Zoo for a scenic walk along the Dunstable Downs. We descend to head West to explore Totternhoe Nature Reserve, before returning to the escarpment. This walk is varied with splendid views, taking in the Tree Cathedral, Gliding Club and NT Visitors Centre. There may be mud after rain. We will visit the NT Visitor Centre on the Downs where there is a cafe, shop and toilets. Bring a picnic.
