We hiked the 14 km (return) to the top of the Cliffs. It’s a 721 m elevation gain. We carried 40 lbs of sand each as we are training for Death Valley. One of us wanted to build a 80 lb sand castle at the top and the other one said, ‘That’s 3 bucks worth of sand!’ So we carried it back down. In hindsight we should have carried a case of beer!
