Mols-Linien is a ferry company, serving the lines between Sjællands Odde on the very western tip of…read moreSjælland, and either Ebeltoft or Aarhus in Jylland. For people going from the area around Aarhus, the second-most populous area in Denmark, to the Copenhagen area, the most populous area in Denmark, there are two options: drive across a large part of Jylland, all of Fyn, and most of Sjælland, or take one of these ferries. It takes about the same amount of time to drive or to sail and drive, but you save quite a bit of driving time, which is nice.
The ferry service is quite convenient, with online and app ticket sales, check-in only 10 minutes prior to sailing, and often quite good discounts on tickets.
The ferries themselves are modern and comfortable. Most of them have a cafeteria, which serves mostly junk food and not very impressive coffee, a restaurant with a decent, but overpriced, buffet, and a coffee shop from the Danish chain Baresso. Go for the latter if you want coffee and something light to eat. If you want a bigger meal go for the restaurant, or wait until you arrive at your destination. Don't bother with the cafeteria.
