If you wear a hat or cap, be careful when climbing the light house. It is very, very windy on the top so that I was afraid to lost my cap. So I put it off from my head and I leaved it in the car. And I recommend anyone to do the same as I did.
Take care of your shoes! There are a lot of Sand dunes there. When I photographed I didn´t realised that I stand in the sand .... and when we came back to the car I had to put off my shoes and even socks because all was full of sand .... !
BUT this sand dunes looked great!
