Sylt is a very nice Island to visit. It is said to be one of the most exclusive places in Germany. You should definetly consider to rent an appartement there. Many people offer holiday flats around Westerland and Wenningstedt. Search the internet for a nice accomodation near those cities. It is the best place to go.
Once there, you should definetly discover the whole island. It is very beautiful! The harbors of List and Hörnum are worth a trip. If you are interested in birds, you can visit the national bird park.
Another idea would be to take a tour with a boat. You can either visit a Hallig, a very small island with only one or two inhabitants or visit the sand banks, where you can watch seals.
Need more ideas? ;-)
