It's easy to reach Denmark by rail from the rest of Continental Europe via Germany. Denmark is also reachable by rail from Sweden and by ferry from Norway and the British Isles.
In this small country, rail goes to most destinations. The notable exception is the western half of the Nordjylland region, the northern edge of Jutland, which is criss-crossed by water.
Most trains have open seating, which means pass holders do not need to make reservations; however, making a reservation is the only way to guarantee a seat.
The S-train connects central Copenhagen with its immediate environs through a series of train lines. These metropolitan trains are independent of intercity rail, and run from about 5:00 a.m. to 1:00 a.m. every day.
Rail Europe offers packages for travelers exploring Denmark, Denmark-Germany, or all of Scandinavia. Discounts are also available to youth 25 and under and seniors over 60.
