Drena, a castle above the Sarca valley

On a terrace above the Sarca valley, behind Dro, Castel Drena is the first thing you see on arrival. The village lies at around four hundred metres, in a landscape of woods, meadows and rock that belongs to the Alto Garda area, and the lake is an easy drive away.

Life is in a small, quiet village with a cooler climate than the valley floor, while Arco and Riva del Garda are close by for schools, work and services. Houses are partly traditional buildings in the old village and partly recent builds; newcomers should bear in mind that in Trentino planning rules and building permits also involve the autonomous Province.

Residents have increased: 597 in 2023, 8.3% more than the 551 of 2011. The average age is 46.5, close to that of the province of Trento (45.4), and foreign nationals make up 6.9%.

Drena is in seismic zone 3, like 146 other municipalities in Trentino, with an expected ground acceleration of around 0.096 g. For an older building, ask for the documents on the structure and any work carried out.

The land registry here is tavolare: the land book is kept by the Province and the Revenue Agency (Agenzia delle Entrate) does not publish cadastral maps, so the report cannot reach the land parcel from the address and flags this. Landslides and rockfall on the valley slopes, however, are checked on the official maps at the exact location of the house.

Landslides and flooding

Landslide and flood hazard changes from one street to the next even within Drena: the report checks the address against the ISPRA maps.

House prices

The Revenue Agency's price ranges per square metre (OMI) apply to zones, not to whole municipalities: the report gives the range for the address's zone.

Land registry

For Drena the Revenue Agency does not publish cadastral maps: the land registry here uses the tavolare (land book) system. The report cannot give a parcel reference, but it still checks risks, services and transport at the address and states this clearly.

Liveability area by area

The Vicinalia liveability index runs from 0 to 100 and looks at the place, not the people who live there: services within walking distance, transport, green space, natural hazards, air, quiet, buildings and connection. Here it is worked out at the centre of each of the 9 inhabited census areas in Drena. Half of the residents live in areas scoring 59 or more.
