Health
Use normal food-and-water caution: standards can vary by place and activity, and hikers/campers should treat backcountry water. CDC notes tick/sand-fly and other bug-bite risks; use repellent and check for ticks after outdoor time. Summers can be hot, while mountains bring strong sun, cold snaps and fast-changing weather; plan hydration, sunscreen, layers and basic first aid.
Vaccinations
Consult a doctor or travel clinic at least a month before travel. CDC lists routine vaccines as the baseline, including MMR, polio, flu, varicella and Tdap/Td, plus staying current on COVID-19. Hepatitis A is recommended for unvaccinated travelers; Hepatitis B is recommended for many unvaccinated travelers. Rabies pre-exposure vaccine may be considered for animal, cave, outdoor or remote-area risk. Tick-borne encephalitis vaccine is for extensive or possible tick exposure in endemic areas. Yellow fever vaccine is not recommended and not required for entry.
eSIM / connectivity
eSIM is usable in Bosnia and Herzegovina, especially in cities and main tourist corridors, but check phone compatibility and registration rules. Local networks include BH Telecom, m:tel and HT Eronet. BH Telecom advertises tourist eSIM packages with data and regional roaming; other local eSIM availability can depend on plan, shop and eligibility. International travel eSIMs also commonly cover the country. Expect weaker service in mountains and rural valleys.
