I like hiking in the mountains.
e-scur-SIO-ni: stress on the third syllable. 'Montagna' = mon-TA-gna, with 'gn' like the 'ny' in 'canyon'.
Use this when describing outdoor leisure activities. It works well in conversations about nature, fitness, or travel. Italians from northern regions are especially enthusiastic about mountain activities.
'Fare' + noun is a very productive Italian pattern for expressing activities: fare escursioni (hiking), fare sport (doing sport), fare shopping, fare una passeggiata (taking a walk). It is more natural than using a specific verb in many contexts.
Adoro camminare in montagna.
I love walking in the mountains.
Uses 'camminare' (to walk) for a simpler phrasing
Faccio trekking ogni estate.
I go trekking every summer.
'Trekking' is widely used in Italian as a loanword
Vado spesso in montagna a fare delle belle camminate.
I often go to the mountains for nice walks.
More conversational and descriptive
The Dolomites in northeast Italy are a UNESCO World Heritage Site and one of Italy's most beloved hiking destinations. Mountain culture ('cultura alpina') is very strong in regions like Trentino-Alto Adige and Valle d'Aosta, with centuries-old hiking traditions.
