The EASA also makes a distinction between <250g drones >250g drones, in terms of registration and permissions required.

However drones remain pretty hard to use across the EU, they're strictly forbidden in most places (cities, natural parks) and for the rest you need explicit permission from the county's aviation authority ( and sometimes even more, e.g. in Portugal if the coastline is visible you also need the Coast Guard's permission). Apparently lots of tourists are unaware and are getting fined for that, there was even a few cases recently where oblivious tourists crashed their drones in historical buildings.
