Lithuania is one of the healthiest, easiest destinations in our index — mild Baltic summers, clean food, excellent doctor coverage and tap water drawn entirely from deep groundwater. Vilnius's old town, Kaunas's modernist streets and the dunes of the Curonian Spit ask very little of a traveller's health planning. The two things genuinely worth knowing before you go: Lithuania's forests carry one of Europe's higher tick-borne encephalitis rates, and summer mosquitoes near the lakes are a real nuisance even though they carry nothing dangerous. Here's the full picture, metric by metric.
Can you drink the tap water in Lithuania? Safe to drink
Yes — and Lithuania is quietly proud of it. The country is unusual in Europe in drawing essentially all of its public drinking water from deep groundwater rather than rivers or lakes, so what reaches the tap in Vilnius, Kaunas and Klaipėda starts naturally filtered and needs comparatively little treatment. Drink from the tap, use ice and rinse fruit normally in the cities and towns on the municipal mains.
The caveats are small. As elsewhere around the Baltic, some groundwater runs naturally high in iron, so in smaller towns or older buildings you can meet a metallic taste or a faintly rusty first draw of the day — legally potable and safe, just let the cold tap run a moment. In rural homesteads using private wells, quality isn't municipally monitored, so bottled water is the sensible choice there.
In practice: tap water is a yes across urban Lithuania, a carbon-filter jug fixes any taste issue, and for infant formula in an iron-rich area, bottled low-mineral water is a reasonable default.
Mosquitoes and insect risk in Lithuania Very Low
Lithuania's lakes, forests and wetlands — Aukštaitija's lake country above all — breed plenty of mosquitoes from June to August, and on a still evening by the water they will find you. It's a comfort problem, not a medical one: there is no established tiger mosquito in Lithuania, no West Nile virus transmission and no locally-acquired dengue. Repellent with DEET or icaridin, long sleeves at dusk and a screened or sealed sleeping space solve it.
The bite that matters here is the tick. Lithuania has one of Europe's higher rates of tick-borne encephalitis (TBE), with risk widespread across the country's forests and grasslands, and the same ticks carry Lyme disease. Hikers, campers, cyclists, anglers and the many visitors who join the national pastime of berry- and mushroom-picking should treat tick precautions as the headline health measure of the trip: repellent, long trousers tucked in, and a thorough skin check at the end of every outdoor day.
How hot does Lithuania get in summer? Low
Summer heat is mild. Vilnius averages a July high around 23°C, and even exceptional heatwaves have only pushed national records into the mid-30s °C. Most summer days are pleasantly warm with cool evenings — pack a layer.
The Baltic coast runs a touch cooler: Palanga, the summer-resort capital, and Nida on the Curonian Spit get sea breezes that keep beach days comfortable, though the long, bright northern days make sunburn easier than the temperature suggests — sunscreen still matters on the dunes. Inland, Vilnius and Kaunas can feel warmer on humid afternoons.
Air-conditioning is uncommon in older guesthouses and apartments, so the occasional hot night can feel stuffy indoors; midsummer nights barely darken around Joninės (St John's Eve), so light sleepers will appreciate an eye mask. Summers can also turn wet and cool quickly — bring a rain layer.
Food and stomach bugs in Lithuania Low
Food safety is good and the risk of a serious stomach upset is low — salmonellosis notifications run at about 15 per 100,000 (ECDC 2021), in the same band as the UK and Belgium. City restaurant hygiene is sound, and salads, ice and fresh produce are no cause for concern.
The table here is hearty: cepelinai (potato dumplings), cold beet soup (šaltibarščiai), rye bread, smoked fish on the coast and curd cheeses — generally very safe, though creamy and cold-served dishes deserve the usual light caution at warm outdoor markets and festivals. If you forage berries or mushrooms, go with someone who knows what they're picking. A few oral rehydration sachets cover the occasional mild traveller's diarrhoea.
Do you need vaccinations for Lithuania? Routine (+TBE)
For ordinary travel, keep your routine vaccines current — MMR and tetanus-diphtheria-polio in particular — and you're covered. Hepatitis A and typhoid aren't routinely advised for a standard Lithuanian trip, and rabies risk is negligible.
The vaccine to take seriously is tick-borne encephalitis (TBE). Lithuania sits among the higher-incidence countries in Europe and the risk is widespread in forest and grassland, so vaccination is worth considering for anyone planning real outdoor time — hiking, camping, cycling or foraging. The primary course spans several weeks, so start well before departure. There's no vaccine for Lyme disease, carried by the same ticks, so avoidance and prompt removal matter regardless.
Healthcare in Lithuania: doctors, pharmacies & the EHIC/GHIC Good access
Lithuania is one of the better-doctored countries in the EU, with roughly 4.5 practising physicians per 1,000 people, and pharmacies are genuinely plentiful at about 47 per 100,000 — among the denser networks in Europe. The pharmacy (vaistinė; look for Eurovaistinė, Camelia or Gintarinė signs) is the natural first stop for minor complaints, and pharmacists in the cities usually manage in English. Younger doctors in Vilnius and Kaunas widely speak English; in rural districts, less so.
Carry your EHIC (or GHIC for UK visitors) for state healthcare on resident terms, backed by travel insurance for private care and repatriation. Private clinics in Vilnius and Kaunas offer fast, English-speaking appointments. Coverage thins outside the cities — on the Curonian Spit or deep in the lake country, the nearest emergency department can be a real drive away.
For routine problems — a repeat prescription, a UTI, a skin complaint, a minor infection — an online consultation can save you hunting for a clinic mid-trip, particularly on the coast or in the countryside.
Emergency numbers in Lithuania 112
The emergency number is 112 — Lithuania runs it as the single unified line for ambulance, fire and police. It's free from any phone, operators can assist in English, and call-takers can locate a mobile caller.
Save 112 before you set off. If you're heading into the lake forests or out along the Spit, note a landmark or your coordinates and tell someone your plans — help is further away than in Vilnius.

Can you drink the tap water in Lithuania?▾
Yes. Lithuania's public supply comes entirely from deep groundwater and meets EU standards, so tap water in Vilnius, Kaunas, Klaipėda and towns on the municipal mains is safe to drink. In a few areas it can taste of iron — still safe — and at rural homesteads on private wells, bottled water is the sensible choice.
Do I need a TBE vaccine for Lithuania?▾
Worth considering if you'll spend real time outdoors. Lithuania has one of Europe's higher tick-borne encephalitis rates and the risk is widespread in forests and grassland, so for hiking, camping or berry-picking the vaccine is sensible — and the course takes several weeks, so plan ahead. City-only trips don't require it, but take basic tick precautions whenever you're on grass or in woodland.
How hot does Lithuania get in summer?▾
Mild by European standards: Vilnius averages about 23°C as a July daily high, the coast at Palanga and Nida runs cooler with sea breezes, and even record heatwaves have stayed in the mid-30s. Pack for warm days, cool evenings and the odd wet spell.
Are mosquitoes dangerous in Lithuania?▾
No — they're a nuisance near lakes and wetlands in high summer, but there's no established tiger mosquito and no West Nile or dengue transmission. Repellent and long sleeves at dusk are all you need. The bite to take seriously is the tick, which carries TBE and Lyme disease.
What is the emergency number in Lithuania?▾
Dial 112 for any emergency — it's Lithuania's single number for ambulance, fire and police, free from any phone, with English-speaking operators.
Is healthcare good in Lithuania?▾
Yes — Lithuania has one of the EU's higher doctor densities (about 4.5 per 1,000 people) and a dense pharmacy network (about 47 per 100,000). Carry an EHIC or GHIC for state care, plus travel insurance; private English-speaking clinics in Vilnius and Kaunas offer quick appointments.
