You’ve booked the trip, packed your bags, and you’re ready to tick off the world’s most iconic landmarks. But there’s something you should know about some of the world’s most-visited attractions: they are genuinely, measurably loaded with bacteria. From the locks on the Pont des Arts to the Blarney Stone, millions of hands, lips, and selfie-stick grips have left their mark — microbiologically speaking.
This isn’t meant to scare you away from traveling. It’s the opposite: arm yourself with knowledge and a little preparation, and you can experience every iconic moment without bringing home anything you didn’t intend to. Here’s what the science says, and here’s how to travel healthy.
The Germiest Tourist Attractions in the World
The Blarney Stone, Ireland
Kissing the Blarney Stone is one of Ireland’s most famous traditions — and one of its most germ-intensive. Millions of travelers per year lie on their backs and press their lips to a stone that has also been touched, kissed, and pressed against by millions of others. Studies have found significant bacterial contamination on heavily touched stone surfaces at popular attractions. That said, the tradition is beloved and the views from Blarney Castle are genuinely wonderful — just maybe carry a small bottle of hand sanitizer for afterward and avoid touching your face.
Love Locks on Bridges (Paris, Prague, and Beyond)
The love lock phenomenon has spread to bridges across the world, with Paris’s Pont des Arts being the most famous example. Millions of padlocks, each one attached by loving hands, create an atmosphere that’s undeniably romantic. But those same locks, handled by millions of tourists, are a congregation point for bacteria. The handrails, bridge surfaces, and surrounding areas attract hand contact from an extraordinary range of people. Enjoy the romance — and wash your hands afterward.
Airport Surfaces
Research published in the journal BMC Infectious Diseases found that airport security trays carry more respiratory viruses than almost any other public surface — more than toilet seats, more than handrails, more than door handles. The plastic security trays that receive your phones, laptops, wallets, and keys are rarely sanitized between passengers. The moral: wash your hands after clearing security, and avoid touching your face until you do. Carry sanitizer in your carry-on (travel-size bottles under 3.4 oz are TSA-compliant).
Hotel TV Remotes
Multiple studies have ranked hotel TV remotes as among the highest-bacteria-count surfaces in any hotel room — higher than toilet seats, higher than bathroom counters. Remotes aren’t typically part of standard cleaning routines. A simple solution: wipe the remote with a sanitizing wipe when you check in, or wrap it in a plastic bag if you’re particularly concerned. This has been standard advice from travel health experts for years and it works.
Cruise Ship Buffets
Cruise ships and norovirus have an unfortunately well-documented relationship, largely because of the close-quarters nature of shipboard life and the communal buffet format. Serving utensils, salad tongs, and sneeze guards are all high-touch points. Modern cruise lines have significantly improved their sanitation protocols — including hand-washing stations at buffet entrances — but travelers can further reduce risk by washing hands thoroughly before eating, using utensils rather than bare hands where possible, and following the ship’s hygiene recommendations.

Museum Handrails and High-Touch Exhibits
Interactive museum exhibits — the kind you’re meant to touch, push, or crank — see thousands of hands per day and are often sanitized only at opening and closing. Even passive handrails along museum staircases and walkways accumulate significant bacterial loads over the course of a busy day. This doesn’t mean avoiding museums (please don’t — they’re wonderful), but it does mean making a habit of not touching your face during your visit and washing hands before eating.
How to Stay Healthy While Traveling: A Travel Advisor’s Practical Guide
The good news is that smart preparation dramatically reduces your risk of getting sick on vacation. Here’s what our travel advisors recommend to every client before a big trip:
Stay current on vaccinations. Before traveling internationally, check the CDC’s destination-specific health recommendations. Some destinations require proof of vaccination; others strongly recommend travel-specific immunizations for things like hepatitis A, typhoid, or yellow fever depending on the region.
Pack a basic health kit. A small zip pouch with hand sanitizer (60%+ alcohol), sanitizing wipes, a thermometer, rehydration packets, and basic OTC medications (antidiarrheal, antihistamine, pain reliever) covers most common travel health situations without adding significant weight.
Be strategic about when you visit crowded attractions. More people = more surface contact. Visiting major attractions at off-peak hours (early morning, late afternoon, or shoulder season) reduces your exposure and usually delivers a better experience. Less crowded = better photos too.
Hydrate consistently. Travel is dehydrating — air travel especially. A well-hydrated traveler has a more resilient immune system. Carry a reusable water bottle and fill it at safe water sources. In destinations where tap water quality is uncertain, stick to bottled water.
Wash your hands properly. This is the single most effective thing you can do. Twenty seconds with soap and water before eating, after using transportation, and after visiting high-touch attractions is more effective than any hand sanitizer.
Get adequate sleep. A tired immune system is a compromised one. The temptation to stay out late and rise early to pack in every experience is real, but burning yourself out in the first few days of a two-week trip is a classic traveler’s mistake.
Travel Confidently — The Germs Won’t Stop Us
The world’s most iconic landmarks are iconic for a reason — the experiences they offer are genuinely extraordinary. A little extra hand hygiene shouldn’t stop anyone from standing on the Charles Bridge at sunrise, touring the Louvre, or kissing the Blarney Stone if the spirit moves them. The key is awareness and preparation, not avoidance.
