Track day in NL OR Germany

Hi, I’m would like to go to a track day. I’m from Hamburg, Germany and I don’t have any race track near by.
If anyone knows and want to go with me, we could go as group. The only option that I know is the Nürburgring and that’s over 500km. I’m open to go to other race tracks in NL, because the distance would be the same.

Best regards
