The UK has been my dream destination for the longest time. In College, I had a fascination, borderline obsession with the UK’s medieval history. It was a dream to see the castles, paintings, and even the burying place of iconic British figures.
That has finally happened and I honestly can’t believe I got to see as many places as I could in just 20 days. I can’t wait to go back that’s for sure.
The UK is such a great destination to spend your 3-week vacation. It comprises four beautiful countries: England, Wales, Scotland, and Northern Ireland. Visiting the UK will make the most out of your annual holiday.
You will get to chill at the beach (if visiting in summer), hike a mountain or two, visit ancient cities and ruins, explore vibrant cities, and, well, finally, have the best fish and chips you will ever have.
In this article, I will show you how to spend 3 weeks in the UK. I will first list things you should prepare before you book anything, and then I will proceed to show you must-see places and must-do activities during your holiday, plus tips on places to stay in each country.

THINGS TO KNOW BEFORE GOING TO THE UK
The United Kingdom, also known as Great Britain, can be confusing to people who are not local. The name Britain came even before the now-known United Kingdom.
When Scotland and Wales joined England in 1707, the name Britain was used. Ireland has always been part of the English colony since the 12th century, but not officially. When Ireland was divided into two, Northern Ireland formally joined Great Britain, and the term United Kingdom of Great Britain became official.
Today, the terms the United Kingdom and Great Britain are used interchangeably. Here are some quick tips for travelling to the UK; before you book anything, take a look and plan your trip properly:
When is the best time to go to the UK
Normally, when we talk about the best time to visit a place for a holiday, the summer season in the Global North is the preferred time to go on a holiday.
But for the UK, the best time to visit is during spring. It’s the time when it’s drier and warmer. Summer in the UK is filled with rain, while winter is freezing and still raining. If you get allergies from the pollen that spring brings, remember to bring your medications.
Are 3 weeks enough for the UK
The UK is not a massive country when it comes to land size; however, there is just so much to see. I really want you to focus on creating a travel itinerary, even though it is just a basic one. In this way, you can see how much you are willing to spend in one place and what type of attractions you prefer to see.
Renting a car will only save you time if you plan to use it anywhere but London. In that city, it’s better to use public transport. But in countries such as Scotland, Wales, and Northern Ireland, having your own vehicle can help you see more places.
Average cost of 20 days in the UK
The cost depends on many things, such as your preferred type of accommodation, dining, and transportation. But to give you a quick idea, $2,300 is a good mid-range budget. You’ll dine out in a private room in a mid-range hotel.
But if you have a tight budget, you can bring that down a little bit to $1,500, where you’d be staying in youth hostels and probably half cooking at the hostel and half eating out.
If you want to make this a luxury trip, $4,500 will be an amazing budget for sleeping in 5-star hotels and eating out at fancier restaurants.
Accommodation will cost the most when travelling in the UK, especially in London, where a room can easily cost as much as $90 per night for a basic mid-range hotel. If you can minimise your stay in London to 2-3 days, it will make a big difference in your budget.
How to get around the UK
The UK have one of the best transportation systems in place. There are domestic flights, buses, and the most popular – train. Sure, they can be annoying for being late sometimes, but it’s still reliable.
If you have an international driver’s license that is valid here, you can also rent a car, which will give you so much more freedom with your schedule.
If you need to get out of the UK, there are a lot of affordable flights going to other parts of Europe. At the same time, Heathrow is one of the busiest airports in the world. Flights here go all over the place, to Latin America, North America, Asia, Africa, and even all the way to Australia.
On the other hand, taking the bus and the train will be more affordable, but you have to plan accordingly to ensure you won’t be wasting too much time in bus terminals or train stations.

Visa
The UK always had a different visa policy than the EU, which is a member of the Schengen States. So, Brexit didn’t really affect travellers visiting the UK.
If you are from an EU country, you can enjoy a 180-day visa-free, the same goes for North Americans, countries from Oceania, some countries in Latin America, Namibia and Botswana, East Asia, Malaysia and Singapore. On the other hand, Ireland has freedom of movement with no time limit.

3 WEEKS IN THE UK ITINERARY
In this travel itinerary, I will be covering all 4 countries in the UK, which are composed of England, Wales, Scotland, and Northern Ireland. I must say, though, this itinerary is a bit packed.
If you want to slow it down or spend more time in other countries, you can cut down some days from England and leave some for your next visit.
If you want to travel slower, you can reduce the number of countries you want to see. Here are a few samples: 7 days in England, 6 days in Scotland, and 6 days in Northern Ireland. You can also try 7 days in England, 6 days in Scotland, and 6 days in Wales. Then explore the country you missed on your next holiday in the UK.
Day-to-day overview
- Day 1: Arrive in London – pick up your car rental if you decide on that
- Day 2-4: Explore London – get a hop-on, hop-off bus tour or The London Pass valid to 90+ attractions

England for 9 days
England is not a very big country, but there’s too much to see; maybe 10 days won’t even cut it. While reliable train connections exist between all the big areas of England, it can still take some time to travel around. Renting a car will give you a bit more flexibility.
England is known for its historical spots, very diverse culture, and people, and it is home to many food hubs and pubs. Not to mention, most Harry Potter film locations are around England (some are in Scotland).
London alone has so much to offer, from history, architecture, adventure, and local pubs. If you are staying right in the city centre, you can see many iconic landmarks just by walking around. You won’t run out of things to do near Tower Bridge and of course Buckingham Palace.
If you only want to see England in the UK, we have an itinerary for 3 weeks in England as well.

If you’re a fan of Harry Potter, there are more filming locations and activities you can do here. Do you know that golf came from Scotland?

Northern Ireland for 3 days
I’m not going to lie; I didn’t have a lot of expectations from my visit to Northern Ireland, but that’s on me for not being aware enough about Northern Ireland. But I was super surprised. I can now say that 3 weeks in the UK are not complete without visiting Northern Ireland.
Northern Ireland (especially the city of Derry) may be known for having a long and dark war history that happened not long ago. Some people might even think that the tension is still as strong as it was about 30 years ago.
There are places you should visit to learn more about the war in the 1990s. There are also so many beautiful spots to see. Many are related to the famous Titanic.
Not to mention how adorable and honestly hard-to-understand accents people have. And if you love whiskey or are simply curious, make sure to try traditional Irish whiskey.
If the Potterheads had their day in Scotland and England, Game of Thrones fans would also enjoy a great time in Northern Ireland.
