Germany has got many islands, however there is one high sea island only. About 70 km off mainland the red sand-stone rock with its green land steeplys stands out against the German Sea. (German Sea = Nordsee) Helgoland – an oasis of quietude and a unique natural monument. There is nothing to compare with it!
Moreover, as you will discover, everything is a little bit different. For instance the sun. People living on the mainland do not even dare to dream of it – as often as it shines upon the island. The climate is favoured by the surrounding Gulf Stream favourably. It gives us the bright but not too hot summer seasons and due to the mild temperatures it ensures during winter time that our "exotic" plants do not get frostbitten.
The special sea current brings us our proverbial clean sand beach. On the dune situated immediately in front of the island you can bath, independently form ebb and flow of the tide, on spacious beaches in healthy and clean German Sea waters.
By the way: in desalinated condition the water has got drinking water norm.

The air itself does not require any special technology. Even on top of the Zugspitze (the highest point of Germany) there are more dust particles flying around than on the island of Helgoland. Here you will neither encounter any car noise toxic exhaust gases, i. e. pure nature – everywhere.
