I did my exchange course in Europe, where I backpacked for 3 months, albeit with a regular break in between. For every 20 days travel, I spent a week resting. My location was Marseille. I'm not going to give a route as such, but some generic tips. Travel : Use your Eurail pass - This is god's gift. I have traveled in the US and Europe wins hands down. You can literally reach any place free with the pass. The moment you step into the train, write on the trip sheet. This helps you save a lot of money (especially in Eastern Europe, where Ticket inspector will try to loot you for non-compliance of rules). Additional sheets can be found online. Reservations are required in France, Italy, Spain in most of the trains. You might be fined if you don't have a reservation. You can reserve online in advance, however, that is expensive than the rates in person. France has differential pricing ( price increases as time reduces ) but others are pretty standard ICE (Germany) is the best. Runs everywhere, no reservation needed. If you are above 26, you have to take first class pass & make use of the lounges, first class travel and the complementary drinks, food etc. Some trains in Eastern Europe has very cheap reservation charges. The momentu00a0 you land in the station, go get your reservation for the return train. Trains in Scandinavia often have free wifi during travel. Utilize them effectively. Accommodation : Stay in a youth hostel dorm always. Europe is way safer than US and a lot of these hostels are well maintained. You connect to a lot of people by this way. Don't get individual room in the hostel unless needed. You can book any youth hostel online using booking.com or hostelworld.com Talk to people in your dorm. I met a Chinese nurse who left her job traveling, a aspiring director from Japan touring, a physical training student from Turkey etc. etc. They often introduce to a lot of local places Irrespective of if you carry a guide book or not, ask for what to do in the reception of the dorm. Believe me, you spending ten minutes in the reception counter is better than any information you get from the book. Generally, you are not supposed to be in your room between 12 noon to 3 noon. Plan accordingly. Food : Try to get the native food at any place. Research helps here.. !!!Since you are backpacking solo, find the company first to have food with. Never have dinner alone.A general meal would cost you around 10 Euro, however, you can finish at a much lower price if needed Sight Seeing: This depends onu00a0 your interest. Europe has a lot to offer on each of your needs. Google to find what in your interest. I'm going to list down my visits and interests Key tip: There is always a free walking tour in any city you go. Do take the tour and it will tell you what you need to see. Take the tour first and you can decide on what you want to see later. It's an all you want to know about the city package. If you are an off beat traveler, stay in a village near the city. You will get to know true native people in village. Bruges : Watch the movie before you go.. A nice place to spend a day around, walk peacefully, absorb a typical European town. It's a small town and you can never be lost here. Go to the tower and have a good view. Amsterdam: Mind I tell you?? In addition to legalization of everything, it is generally a mind blowing place. Take a walk in the night, starting from the railway station, to the canal, through the strip clubs. Paris*: Spend a day in Louvre, with the headset. Pick some random museums and Paris will never fail you. Go the versailes palace and enjoy the gardens. Go to Notre dame and walk through Champs-u00c9lysu00e9es. Marseille: Spend some time in the Calanques and the port. Spend a peaceful day in the Pope's old palace in Avignon, walk through the broken bridge in river Rhine, enjoy the Provence region. Barcelona*: My favorite place in whole of Europe. Bask in the creativity of Gaudi, immerse yourself in the dominance of historic buildings and the catalan culture. If you are into football, camp nou is a must visitMadrid: Definitely the Prado Museum. A treat to your eyes. Bull fighting zone. Nice: Better not to stay in Nice or Cannes, but go to any beach you like in the French Rivera. Your Eurail pass will help. Cinque Terra : Take a walk across the five small villages and the dotted coast line. Worth a day Rome*: Vatican Museum, St. Peters' Basilica, Pantheon, Colloseum, Palantine Hill & so on. Easily a week here. Athens & San Santorini: Islands around Athens, the temples in Athens, and San Santorini in the night. Meteora: Not much population. A leisurely visit to some of the orthodox monasteries in Greece. Sophia: Time for you to splurge. Everything is cheap, and a decent place, though not much to see. Bucharest: Parliament, the 2nd largest building in the world. Budapest*: Amazing history, walk over the chain bridge from the Danube river, view the Hungarian parliament, with the palaces on the background, go on the Danube Cruise. Weekend special spa parties are great & don't miss them. Bratislava: Good small town, leisure walksZagreb: Visit Plitvice national park*. This is a must, you will be amazed. There is also a museum of broken relationships here. Dubrovnik: GoT fans.. Must visit.. Venice: Buy a hand map. Only place so far, where google maps failed. Spend the evening in St. Marks Square. Go to the surrounding islands. Take the normal Gondola trips used by Venetians. Ljublana: Take a walk around the quiet city. Take a bicycle and go to the mountains around the city. Stay in a village. Vienna: Counterpart of Hungary. Historical museums. Do attend the Opera. There are shows in English and look out for them. Worth the visit. Salzburg: Ice caves, depends on when you go. Prague*: Palace, strip clubs, night walk in the city. The night trams are really goodMunich: City walk, Oktoberfest, can't beat that atmosphere. Berlin*: The power center. The city offers what you want to see. History, politics, museums, pubs, night life, everything packed together in one place. Gothenburg: Archipelagos are really good. Go to Vrango. There would be no one and the houses are beautiful Finland: Go to the fish markets, talk to a finnish guy about Nokia, the rock church Bergen*: Do take the Fjord trip. Worth every aspect of it. Serene natural beauty. * are must visits for me. Visa: Countries in the edges require individual visas. However, if you are in Schengen zone, single visa will suffice. General inputs: Weather will play a key role in your travel. Try to travel from July, august since weather would be pleasant and good in most of the places. Keep your apparel part of luggage small. There is no need to take a full wardrobe and travel Every city has a tourist center in the railway station. Reach out to them for help, getting maps etc. They all speak English In buses, always ask if you have to stamp a ticket. Buying, but not stamping is equivalent to ticket less travel. Rest in between. For every 10 days of walking, traveling, stay 2 days in a off beat place (read village, small towns). Don't do any sight seeing. Just spend some time resting. This helps a lot. FB is a good tool. Check-in to places you went to, post selfies etc. Even after several years, it will remind you of the good times. Washing machines in youth hostels generally do not have dryers and drying your clothes is weather dependent. Lot of places have student discount. Get your ISIC card, if you are a student. I'm hoping this would have helped you in some ways. Happy traveling.. !! Do post your experience..
