Yes. Spain's US State Department rating is Level 2 ("exercise
increased caution") — the same as France, the UK, Germany, and
most of Western Europe — and the elevated level reflects
generic European terrorism risk, not anything specific to
Peñíscola. Peñíscola is one of the safer stops on our Spanish
catalog; the small-town geography helps and the walled old town
is fully pedestrianized. Violent crime against travelers is
very rare. The actual risk is minor pickpocketing in the
summer-festival crowd inside the walls and the ordinary
seaside concerns — sun, surf, and slick wet limestone after a
rain shower.
On a Passports teacher-led trip, the group moves by private
coach with a professional driver, 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 Spain, the Peñíscola
half-day feels like the easiest stop on the itinerary because
the Tour Director owns the castle entry, the coach drop, and
any curveballs end to end.
