If the company will pay, yes. Otherwise I would say no.
I would expect this trip to take at least a day and cost at least three figures of Euros. If the company is happy to cover the costs and have you take a day traveling instead of working then great. You get to meet your boss and build a personal bond. It really helps long distance communication for your emails to be going to a person you have met rather than an email address. It is quite possible for the company to be happy to pick up the tab for this "team building exercise". However if they are not, and you would be paying out of pocket and perhaps even making up the time, then the company does not think it is worth it to them so it is probably not worth it to you.
An additional consideration is the environmental footprint of the trip. As this will require two flights of about 1000 miles each this is not likely to be negligible. It will be for you to weigh this against the value you would get from the meeting, your company may not consider it at all.
