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 Nice or the Côte
d'Azur. Violent crime against travelers is rare; the city's
visible safety profile is comparable to any French city its
size, and the Promenade and tourist core are continuously
monitored. The realistic risk is opportunistic pickpocketing on
the Promenade in summer, in the Cours Saleya market, and at
Nice-Ville train station on TGV-arrival mornings.
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 the Riviera, Nice feels easier than a domestic
field trip once the first morning is underway.
