They include the coast off Texel, Rees, Marbeck, Emmerich, Hamm, Ostonnen, just north of the Mohne Dam, the former airfield at Gilze-Rijen in Holland and Castricum-aan-Zee, also Holland. The Dortmund-Ems Canal sites are Noordhorn, Recke, Bergeshovede, Ladbergen and Den Ham in Holland. All these sites can be visited within a week’s tour by car or public transport.
