The water has no tide, is mostly perfectly flat with small wind waves. 1km of shallow water. Beware of the wooden wave breakers right in front of the beach.
The beach is nice and soft. There are some groynes but in respect to the shallow water you can easily walk around them. Be careful of the trees nearby the beach. Off season is from September till May. There is enough space to launch and land the kite. During season it may get more crowded.
After you reached the island Usedom while coming over the Zecheriner Bridge (get the opening times via Internet) you follow the signs Ahlbeck/airport. Take right hand crossing in Zirchow to direction Kamminke. Passing the `Golm` you will be leaded into the harbour of the small village Kamminke. This road will lead you to the water, in front of the dam turn right and follow that small road along the dam to the parking lot. Park here (free). You can stay overnight and they will charge you about 4-6 Euro (depending if the old man likes you or not).
