Travel Tips

Welcome to Potsdam, the city of majestic palaces and picturesque parks! To make your trip to this wonderful corner of Germany as comfortable and memorable as possible, we have prepared some practical tips.

  1. Clothing and Essentials:

    The climate in Potsdam is temperate. In summer (June–August), it is usually warm, so light clothing is appropriate. In winter (December–February), it can be cold, so pack warm layered clothing, a hat, gloves, and a scarf. Spring and autumn have mild but changeable weather—layering is best. Comfortable shoes are essential, as you will be doing a lot of walking in vast parks like Sanssouci and palace complexes. Don't forget a European adapter (Type F) for your electronic devices. There is no specific dress code for most places, but modest clothing is appreciated when visiting churches.

  2. City Transport:

    Potsdam has an excellent public transport system, including trams and buses (operated by ViP - Verkehrsbetrieb Potsdam). The city is also conveniently connected to Berlin via the S-Bahn. Consider buying a Potsdam AB day ticket or a WelcomeCard if you plan to move around a lot. Taxis are available, and ride-hailing apps like Uber or FreeNow also operate. Renting a car to see Potsdam itself is generally not necessary due to the good public transport and many pedestrian zones near historical sites. Furthermore, parking can be difficult and expensive. A great alternative is a bicycle, especially for exploring the parks.

  3. Finances:

    The local currency is the Euro (EUR). Credit and debit cards (Visa, Mastercard) are widely accepted in hotels, most restaurants, and large shops. However, it is always useful to carry some cash for small cafes, markets, or in case cards are not accepted. ATMs (Geldautomat) are easy to find throughout the city. An approximate daily budget per person (excluding accommodation) can be €50–€100 for food, transport, and small expenses. Tipping (Trinkgeld): in restaurants, it is customary to leave 5–10% of the bill if you enjoyed the service. You can round up the amount or say "Stimmt so" (keep the change). Small tips are also appropriate for taxi drivers and hotel staff.

  4. Health and Safety:

    Pharmacies (Apotheke) are easily recognizable by a red "A" sign. They are found in all districts. Information about on-duty (24-hour) pharmacies (Notdienst Apotheke) can be found on any pharmacy door or online. EU citizens are advised to have a European Health Insurance Card (EHIC). Tourists from other countries should arrange travel medical insurance. In emergencies, call 112 (the general emergency number). Potsdam is generally a very safe city. However, take standard precautions: watch your belongings in crowded places and on public transport. Try to avoid poorly lit and deserted park areas after dark.

  5. Communication:

    The official language is German. English is quite common, especially among younger people and in tourist areas. Nevertheless, knowing a few basic German phrases will be very helpful and appreciated by locals: "Hello" – Guten Tag (Goo-ten Tahg), "Thank you" – Danke (Dan-keh), "Please" – Bitte (Bit-teh), "Yes/No" – Ja/Nein (Yah/Nine), "Do you speak English?" – Sprechen Sie Englisch? (Shpreh-khen Zee Eng-lish?). SIM cards can be purchased at supermarkets, electronics stores, or mobile operator shops. Free Wi-Fi is available in many cafes, hotels, and some public spaces. Public transport apps (e.g., VBB Bus & Bahn) and maps (Google Maps, Maps.me) can be very useful.

  6. Local Etiquette:

    It is customary to say hello (Guten Tag during the day, Guten Morgen in the morning, Guten Abend in the evening) when entering small shops or addressing staff. Germans value punctuality; if you have a meeting, try to arrive on time. In public places, it is customary to behave discreetly and not talk too loudly. When addressing strangers, especially older people, use the polite form "Sie" (You) rather than "du" (the informal you).

  7. What to Avoid:

    Do not cross the street on a red light, even if no cars are nearby. This is considered a serious violation, can lead to a fine, and will be frowned upon by locals. Also, try to avoid excessively loud behavior in public places, especially on transport and in restaurants. Germans value peace and order.

  8. Extra Tip for Potsdam:

    Plan your palace visits in advance. Especially during the tourist season, it is better to book tickets for palaces like the famous Sanssouci online. This will help avoid long queues and guarantee entry at a specific time, as the number of visitors per day is often limited. Also, keep in mind that the parks around Potsdam's palaces are huge, so allow enough time for leisurely walks to enjoy their beauty.

We hope these tips help you better prepare for your trip and get the most out of your stay in Potsdam. We wish you an unforgettable journey through this historical city!

Getting Around

Public transport in Potsdam is well-developed and offers convenient ways to move around the city and its surroundings. The transport system is based on trams and buses, with a route network covering almost all districts. Additionally, S-Bahn commuter rail lines pass through Potsdam, providing fast connections to Berlin and other towns in the region.

Potsdam is part of the Berlin-Brandenburg Transport Association (VBB), which means a unified system of tickets and fares. For travel within the city, a ticket for tariff zone AB is usually sufficient. Various types of tickets are available: single (Einzelfahrschein), short distance (Kurzstrecke), daily (Tageskarte), weekly (7-Tage-Karte), and group day tickets. As of early 2024, the approximate cost of a single ticket for the Potsdam AB zone was about €2.50, and a day pass (Tageskarte) was about €5.00.

Tickets can also be bought via mobile apps like VBB "Bus & Bahn" or BVG Fahrinfo.

Before starting your journey, a paper ticket purchased from a machine or counter must be validated (stamped) in special yellow or red machines located on platforms or inside trams and buses. Tickets purchased from a driver or via a mobile app are usually valid from the moment of purchase and do not require additional validation. Fines for fare evasion are quite high.

Public transport in Potsdam runs according to a schedule, which can be found at stops and online. During the day, intervals are quite short. At night, special night bus routes operate, though with longer intervals. Overall, the system is reliable and makes it easy to reach most attractions.

In addition to public transport, other modes of travel are popular in Potsdam. Cycling is an excellent choice for exploring the city, thanks to a developed network of bike paths and numerous rental points. You can also use taxis, with ranks located at stations and in the city center. Car-sharing services are also available if you prefer to travel by car.

One pleasant feature of Potsdam's transport system is the ferry crossings, which are part of the VBB system and allow for scenic water trips across the lakes and the Havel River. For example, the F1 ferry connects the Hermannswerder and Krampnitz districts. This is not only a convenient way to reach some parts of the city but also a chance to view Potsdam from the water.
