Malta had the highest proportion of nights in tourist accommodation spent by tourists from other EU countries (84 per cent), according to Eurostat.
The statistics, released to mark European Tourism Day 2018, showed that last year, EU citizens made a total of 1.2 billion tourist trip across the bloc.
The vast majority of these (94 per cent) were to destinations within the EU, often within their own country of residence.
The European Union’s statistics agency said that the highest proportion of overnight stays undertaken by residents within the country or non-residents from other EU countries in 2017 was in Poland (94 per cent).
Meanwhile, Cyprus had the highest proportion of nights in tourist accommodation spent by tourists coming from outside the EU (36 per cent).
For the EU as a whole, half (52 per cent) of the nights were spent by people who were residents of the reporting countries and 35 per cent were spent by non-residents from other EU countries. Tourists from outside the EU accounted for the remaining 13 per cent of nights.
