On Thursday, October 1, Vladimir Putin said Russia would use “all weapons” at its disposal if Kaliningrad were attacked, and the remark has travelers asking whether a trip to Poland, Lithuania or the other Baltic countries is still a good idea. This is what is known so far, and what official guidance says today.
What happened
Kaliningrad is a heavily militarized Russian exclave between Poland and Lithuania, slightly larger than Connecticut. According to CNN, Russia sent a diplomatic note to NATO this week warning of a possible nuclear response if the alliance tried to cut the territory off. Putin repeated the warning at a conference on Thursday, while also saying Russia has no plans to attack European countries. NATO Secretary General Mark Rutte replied that the alliance is defensive and that nuclear threats are unhelpful.
Reports tie the rhetoric to recent NATO exercises near Kaliningrad and to a standoff over Ukraine. None of the articles we read described any change to flights, border crossings or tourist access in Poland or the Baltic states.
What U.S. travel advisories say
We checked the State Department pages on October 2. Poland, Lithuania, Latvia and Estonia are all at Level 1: exercise normal precautions. The Poland advisory was issued in June 2025, Lithuania’s in April 2026, Latvia’s in April 2026 and Estonia’s in March 2026, so none was updated in response to this week’s statements. The advisory for Russia is Level 4: do not travel, citing terrorism, unrest and wrongful detention risks, and it was last issued in December 2025.
How to plan sensibly
- Do not plan any trip to Kaliningrad or elsewhere in Russia. The U.S. government advises against travel there for any reason.
- Enroll in the State Department’s Smart Traveler Enrollment Program (STEP) so the embassy can reach you with alerts.
- Buy travel insurance and ask your provider about evacuation, medical and trip cancellation cover.
- Re-check the advisory for your destination shortly before departure, because levels can change quickly.
This is not a security forecast. Governments, not travel blogs, are the right place to check for changes, and tensions between Russia and NATO can shift fast.
