Small mountain and mixed farms produce dairy, apples, hops, buckwheat and vegetables, but the country is a net food importer and self-sufficiency is only moderate for many products. Local, seasonal eating is straightforward through farm shops and markets.
Local staples
Potatoes, buckwheat (zganci), beans, cabbage and turnip, dairy, apples and struklji dumplings.
Markets
Daily central market in Ljubljana; weekly town markets, often on Friday or Saturday.
In season
Apples, grapes and pumpkins (and pumpkin-seed oil) in autumn; hops in the Savinja valley in late summer.
Wildlife

Slovenia holds a healthy large-carnivore community of brown bears, wolves and reintroduced lynx, and its Dinaric karst is a global hotspot of subterranean endemism, home to the olm (Proteus anguinus) and many endemic cave invertebrates. There are 84 threatened species recorded (IUCN via World Bank, 2022).
Found nowhere else
The olm (Proteus anguinus), a blind cave salamander of the Dinaric karst, and a rich endemic subterranean cave fauna.
Natural phenomena
Alpine north, Mediterranean south-west; hot summers and snowy winters in the Julian Alps.
When to go
Late spring to early autumn; winter for the Alps.
Getting around
A compact country where buses and trains link towns and a car easily reaches the Alpine valleys.
Good to know
Cards everywhere; EUR. A small country where a car unlocks the best.
Safety

| Plant based and real foodWhether you can eat unprocessed from local supply | 3/5 | Hearty traditional cooking makes good use of vegetables, beans, buckwheat (zganci), potatoes and turnip, and produce is plentiful at markets and farms. Full assessmentVegetarian and vegan options are still developing outside Ljubljana, so plant eating is available and modest rather than second nature. |
| OrganicCertified and chemical free growing, which is not the same thing as plant based | 4/5 | About 10.8 per cent of Slovenia's agricultural land was organic in 2020 (FiBL, The World of Organic Agriculture), among the higher shares in Europe and supported by extensive grassland and … Full assessmentountain farming. |

Per-person emissions are mid-range at about 6.02 tonnes of CO2 in 2024, weighed down by transport and industry.

Living heritage and ancestral traditions
The culture still danced, played and believed
Slovenia's best-known living tradition is Kurentovanje, the riotous late-winter rite in which men in sheepskin costumes and horned masks, the Kurenti, parade to drive away winter, a custom of ancestral pre-Christian origin recognised by UNESCO. Alpine-style polka and waltz music remains popular, shaped by the Avsenik ensemble. The Skofja Loka Passion Play, one of Europe's oldest surviving directed plays, is still staged by the townspeople. Beekeeping is treated as a cultural way of life, with painted hive panels and a distinctive craft heritage.
