Most travelers neglect the option of using planes to travel across Europe. Flights within Europe are generally cheaper than domestic flights in Canada and some great deals can be found, especially in London. If you're planning to go to Ireland, or want to dash down to Greece or Spain without stopping to sightsee along the way, you may find that it's not much more expensive to fly and certainly much more pleasant than the train or boat. Train The most common option for European travel is train. Trains are quick, efficient, and can take you everywhere from the largest cities to tiny villages, with an abundance of departures each day.
Train passes are also unparalleled for their flexibility.
They can be purchased for unlimited travel in almost all of continental Europe for up to 3 months, or for only a limited number of days in a limited number of countries. However, one of the best bits of advice I received was that if you have a little extra money, the best thing to do with it is to upgrade your rail pass, either to add more days to a flexipass or to upgrade to an unlimited pass. I purchased an unlimited travel 2-month pass and likely could have made do with a cheaper option but as a single traveller I wanted complete freedom. I never had to plan out how many days I had left or attempt to outsmart the train conductors by cheating on my flexipass. An unlimited pass is a luxury that may not be in the budget for some travellers, but it was one that I found was worth the extra money.
