Yes. France's US State Department rating is Level 2 ("exercise
increased caution") — the same band as Italy, the UK, and
Germany — and the elevated level reflects generic European
terrorism risk, not anything specific to Strasbourg. The city
sits visibly below the French national average on violent
crime, partly because the European institutions push a heavy
police and security presence year-round. The realistic risk is
opportunistic pickpocketing at Strasbourg-Ville train station
and on the tram lines that run between the cathedral and the
Parliament, plus elevated street activity during the December
Christmas market.
On a Passports teacher-led trip the group is never on public
transport alone, the Tour Director runs a pickpocket-awareness
briefing on the first evening, and every hotel is pre-vetted for
24-hour reception and secure room storage. We operate a 24/7
emergency line out of Boston, keep parents on a daily-update
channel, and have English-speaking medical contacts in every
city we visit. For most teachers running their first school
group tours to France, Strasbourg feels easier than Paris on
the safety side and every bit as rich on the curricular side.
