How to Plan a 3-Week Europe Itinerary

1. Decide where you want to go

Define what you want to get out of the trip. Is your group interested in history, art, food, adventure, relaxation, or a mix of these? Your interests will guide your choice of destinations

2. Choose your destinations wisely

Research various countries and cities to find ones that match your interests. Aim for a balance between popular spots and lesser-known destinations for a well-rounded experience.

3. How many countries should I visit in Europe in 3 weeks?

This is a personal choice. How often do you want to move accommodation? For three weeks in Europe, we recommend 3 to 4 different locations. Note that travel time between locations can significantly reduce the actual time you have for exploration.

If it is your first time visiting Europe be sure to leave enough time to make connections. Opt for destinations that are closer together or well-connected by efficient transport networks.

4. How Much to Pack for 3 Weeks in Europe

For such a long trip we recommend liming luggage to the essentials. Choose items that mix and match and pack layers.

The weather can vary greatly across Europe, so be sure to check the weather during your trip and pack appropriately.

If it’s an option, book accommodation with a washer and/or dryer so you can pack fewer clothes. Remember, you’ll probably pick up a few souvenirs along the way.

5. Don’t overplan your trip

While it’s tempting to try and see everything, cramming too many activities or cities into your itinerary can lead to burnout. Allow for downtime and spontaneous exploration, especially when traveling with younger kids. Flexibility is key.

6. Research Visa Requirements

Some countries may require visas for entry, so ensure that you’re aware of these requirements and prepare accordingly.

*Note: Starting in 2024, Americans will need authorization through ETIAS to visit 30 European countries. For more information, we recommend this website.

7. How Far in Advance to Book a Trip to Europe

This really depends on your schedule and availability. It also depends on the time of year you plan to travel.

We recommend booking flights and accommodations at least 6 months in advance to get your first choices. Be sure to book your intercity train or plane tickets at the same time.

If there are any must-see attractions or experiences on your list, be sure to book those in advance to prevent disappointment.

8. Purchase Travel Insurance

I’ve had to file two claims in the last two years and I wouldn’t recommend traveling without insurance right now. Travel insurance can provide coverage for unexpected situations such as medical emergencies, trip cancellations, or lost luggage.

9. How to Stay Connected in Europe

Consider your options for staying connected, such as getting a local SIM card or portable WiFi. Each carrier offers different coverage. T-Mobile offers an international calling plan, whereas Verizon and AT&T offer a daily rate. Another option is to set phones to airplane mode and use Wi-Fi when available.

Recently we discovered eSIM cards which are very easy to use. Just download the app to your phone and connect through it. We used Airalo and felt it was a great option.

10. How much should I budget for 3 weeks in Europe?

Unfortunately, it’s not a set number. Nordic countries are typically more expensive than the rest of Europe. Southern countries like Greece, Portugal, and Spain are relatively inexpensive as are the former Yugoslavian countries, Bulgaria, and Romania.

Depending on your travel style and how many people are traveling with you, I think it’s safe to plan on $1000 minimum per week.

Research and plan your budget carefully. You’ll need to be sure to account for transportation, accommodation, food, attractions, and tours at a minimum. We recommend you always carry emergency cash just in case.
