We are just leaving after 2 weeks starting in Amsterdam then a barge/biking week from there through Antwerp, Ghent to Bruges where we stayed several days.
From a Covid standpoint, masks are required indoors and on public transportation. All museums and public sites are open. Some shops have closed but most are operating. Must have negative test here tó return to US ($50 approx)
Weather is wetter than normal according to locals but overall ours has been fairly good.
Bottom line, our experience was generally 'normal'. However, would only travel here if fully vaccinated.
