Hello. I just found where my great grandfather came from after searching for this for decades. Arlen Germany north of the German Swiss border in Konstanz District. Does anyone have any travel tips for this area? Hope to be there in May. Thank you!
Only a few kilometers on the Swiss side of the border where the river Rhine leaves the Bodensee (Lake Constance) there is the beautiful little town of Stein am Rhein (Stein on the Rhine)
https://tourismus.steinamrhein.ch/de/ Beware of the prices in Switzerland. The cost of living in Switzerland is nearly double as high as in Germany (for people living in the Euro zone). Arlen is a part of the town of Rielasingen-Worblingen, which has about 12,000 inhabitants.
