Denmark rail pass

The Copenhagen Metro is not a private company and is under the same ticket system as the Copenhagen S-train, Copenhagen busses and DSB Øresund, so logically the railpass should cover the Metro as well. But i would check the fine print anyway.
To find prices and travel times for all puplic transport in Denmark use www.rejseplanen.dk

"For ferries the website says:

"Fjord Line, Scandlines, Stena Lines"

Would these cover any ferries that one might need to take between the islands?"

Which Islands? there are over 400 islands in Denmark and the biggest one are connected by bridges.

Thanks for a quick response, Morten. I suppose my main concern would be ferries connecting Funen & Aero; possibly, Zealand & Mon; and Jutland(Aarhus) and Zealand.

http://www.aeroe-ferry.com/home-en/#/ operate the ferries to Ærø. Århus is connected by train via bridges and Møn via train and busses, which your pass will likely cover.

I don't believe there's any more full ferry coverage with a rail pass anywhere in Scandinavia; only occasional discounts. I don't see those described as you quote; both http://www.eurail.com/eurail-passes/pass-benefits/benefits-denmark and our Rail Europe purchase page are a bit more specific about discounts (which do not use a counted rail pass travel day).

Eurail states that the suburban S-Bahn is covered, but does not mention metro in-city, which is not covered with most rail passes in most cities. Nothing is ever "free," the better description is "covered" when you are using a counted rail pass travel day, usually to connect to or from longer-distance trains.

Thank you!
