Understand the prices vary from France to Belgium depending on who is traveling and how long you want to stay. Prices range from $150 to $520 for a 4- to 10-day pass.
Choose your ticket class. Second class is standard and cheaper, but is more crowded and offers fewer amenities than first class. The cost difference can be about one-third less in price for second class.
Know that adults can book an individual pass or Saver Pass (two or more people). The more people that travel, the better the price.
Take advantage of discounts on second class travel from France to Belgium for those passengers under the age of 26, anywhere from 25 to 50 percent of an adult full price fare.
Find your departure platform, designated by the French word "quai," by reading signs in the French train station.
Purchase food for your journey to Belgium before boarding your train in France, as many trains do not have lunch cars, contrary to popular notions.
Carry your Eurail pass on you so that you can produce it when asked by a conductor and purchase travel insurance while booking your ticket to avoid losing fare price for lost or stolen tickets.
