Start from the Passo Sella bus stop and follow the signposts to Naturonda. You will come across Città dei sassi, resting at the bottom of the northern, vertical walls of the Sassolungo; continue on a jaw-dropping journey through a marvellous natural landscape. Information boards, placed along the walk, offer interesting titbits on local flora and fauna such as descriptions, food foraging and the habitat of wild foxes, rabbits and groundhogs living in Val Gardena. The boards also list interesting trivia on flora, geology and regional herbs. Return back on path number 526.
