The sand dunes look pleasant, inviting, however, looks are deceiving. Walking up a slope is an arduous task. Every step up comes with a slide down most of the time 75% of the step is lost. Other times it’s almost 100%. I found myself getting on all fours to climb up the slopes. Once up to the ridge, it was still a challenging ordeal but not as taxing. The reward: Great vistas, solitude, and the challenge of another dune just ahead.
