Croatia is a country at the crossroads of Southeast and Central Europe, which shares a coastline along the picturesque Adriatic Sea. This country has a beautiful overall climate, with more than 2,500 hours of sun per year, picturesque ports, stunning cities, hundreds of islands, and the most beautiful coastline in Europe.

Croatia is known for its scenic pebbled beaches, lavender fields, Pag cheese, and Ancient Roman Ruins, as well as being one of the locations where Game of Thrones was beautifully filmed. You could see or experience these and more if you stay for 3 weeks in Croatia.

In December 2022, Croatia was accepted to be part of the Schengen State (although it has been part of the EU since 2013). There will be some changes to its rules, specifically in travel. These pointers are essential to consider before travelling to avoid any mishaps or hassles and will also help you write your own travel itinerary.

When is the best time to go to Croatia

The summer season is from June to September, perfect for swimming, sailing, and island hopping and is what Croatia is famous for. Those months are also the country’s peak season, while its winter season is from December to February. Its rainiest month is January.

The low season in Croatia is from October all the way to April. To those who are not looking to get on the water that much, you might want to avoid the high cost of peak season and travel during these months.

Are 3 weeks enough for Croatia

You can see and explore many places in Croatia in 20 days, but it all depends on what you want to do and planning your trip. If you want to travel slowly, you can visit 3-4 cities and take your time exploring. Then 3 weeks might be sufficient.

But if your goal is to see as many places as possible, either check if you can extend your stay or expect that you will be spending most of your time on your feet and making sure that you don’t miss any train, bus, or flights.

One smart way to make the most of your time in Croatia is by listing a few key areas in mind. For example, list the top sites highly related to the country’s history if you love history. If you want to do lots of water activities, list the excellent places for this plan.

This will allow you not to feel rushed and make sure you see the places that matter most to you. Overall, 3 weeks in Croatia is a reasonable amount of time, especially if you visit during the off-season when the queues are not too long.

What to pack

What to pack for Croatia differs a lot on a few things. Due to its location, the temperature can vary greatly depending on the season. If you plan to visit during peak months which is the summer, everywhere in Croatia gets pretty much warm.

During that time, you want to make sure that you pack enough sunscreen, a hat, and breathable clothing. Bringing reliable walking shoes or sandals is also a must since holidaying in Croatia means hours of being on your feet while exploring.

But for those who decide to visit in the winter, springtime, and autumn seasons, it’s best to plan to do some layering to stay warm. Don’t plan on bringing thick and heavy jackets, as they will take up lots of space in your luggage.

Finally, if you have been prescribed medicine, bring enough with you. You should also pack the prescription letter with you. Although it’s not 100% that you can refill it in Croatia, it’s better to have the prescription letter. We have a general packing list for a 3-week trip or you can also check out our summer packing list.

How to get around

Driving is the best way to get around Croatia as it is convenient and flexible. The roads are also wide, modern, and easy to navigate. Croatia acknowledges driving licenses issued by most countries, including the EU, North America, Latin America, Africa, Oceania, and some parts of Asia.

However, most cars for rent in Croatia are manual (just like in France and Spain). Make sure you are comfortable driving a manual transmitter. If you have an IDP (International Driving Permit), that is also acceptable in Croatia.

Public transport is more appropriate if you are either a solo traveller or budget conscious. However, some destinations have limited bus lines, and inter-city transport takes time. You can use Flixbus to book your bus and get a digital ticket.

Carpooling is another option if you have a tight budget and want to visit more than one place. Otherwise, you can opt for a private transfer if you prefer not to drive and are willing to splurge on transportation costs.

Language and currency

Croatia’s most spoken language is Croatian, followed by Bosnian and Serbian. Aside from that, English is also widely spoken and taught throughout the country, along with German and Italian. Many Croatians are actually bilingual or multilingual.

The current currency in the country is the Croatian Kuna. However, starting January 2023 will begin using Euro since it’s been accepted to be part of the Schengen State. Major debit and credit cards are accepted in most hotels and restaurants, but it’s also better to be prepared and bring cash.

Average travel cost for Croatia

The average travel cost for Croatia will depend on a few factors. This includes the season you plan to go, how many people are going, and what kind of trip you have in mind (tight budget, mid-range, luxury). We also have an article of itineraries if you want to do Europe on a budget for 3 weeks.

Accommodations in Croatia, in general, are decent. For two people, a mid-range double room should cost around $45 per night. A bed in a hostel dorm room is approximately $12, while a luxury hotel room is about $100.

Transportation and food are also relatively cheap. Flights getting to Croatia could be the most expensive on your list, especially if you travel from the Americas or Asia. From Europe to Croatia, you should be able to find flights as cheap as $70 for one way.

For 20 days in Croatia, the average cost is about $1,500 per person, excluding the flights. If you plan to stay in hostel dorms, you can make the trip for under $1,100.

Visa and COVID-19 protocol

Croatia is part of the EU which means it implements the same visa policies as the other European Union members. In general, travellers with passports issued by most countries in the Americas (except Ecuador, Bolivia, Guyana, Suriname, and French Guinea), New Zealand, Australia, Japan, South Korea, Malaysia, Singapore, and the UK can enter and stay in Croatia for up to 90 days in a 180-day calendar. Travellers with passports issued by an EU member have the freedom of movement in Croatia.

Starting January 2023, Croatia will be part of the Schengen States. This means that there is now an open border policy between Croatia and the other 26 other European countries. If your passport is from the mentioned countries under the 90-day rule, you can only stay for 90 days in the area of Schengen States (not each country).

Croatia started to welcome international visitors again in June 2021. As of writing this article, there are no restrictions at the moment. It is required to wear masks in closed spaces such as public transportation. However, rules can vary. You don’t need to show COVID-19 vaccination card or antigen test to enter Croatia.

Other travel tips

To make your travel planning a little easier, here’s a quick list of the travel services I personally use. These travel sites have wide selections suitable to everyone regardless of your travel budget, as they offer options for those on the budget, mid-range, and people seeking luxury.

I also enjoy that many travel booking sites allow me to cancel my reservation even at the last minute. This means you can book in advance, choose the best hotels, and then cancel later if your travel date changes without losing too much money.

Zagreb has fewer tourists than other more famous places in Croatia, but it doesn’t mean it has no charms. In fact, it’s quite the opposite. Zagreb is filled with historical sites comparable to a hybrid version of Budapest, Vienna, and Prague.

The cost of living here is super affordable by European standards, and it is a perfect starting point as there are tons of available day trips. Even flights from here to neighbouring countries are super cheap. If you plan to travel with a vehicle, pick up your car rental in Zagreb and make sure you can drop it off in Dubrovnik.
