Yes, this activity requires a lot of concentration as you can see !!
Like in Zagora, we spent the night eating tajines, telling stories, playing music and singing a little (especially our Berber guide because we don't speak Berber ;-)
Nothing's much more fun than climbing up a gigantic sand dune for nearly an hour and then sitting down on it's crest to watch the sunrise or sunset and then running all the way back down the dune so fast that you lose your balance and tumble in the powder like sand.
This is an amazing show, the moon, the sand dunes and the lake give and outstanding scene that you'll never forget.
