3 Weeks on West Coast USA Itinerary

DISCLAIMER: This post might have links to travel services and products that we enjoy. We might make a commission from it at no extra cost to you.

On my first trip to the US, I planned to only visit the East Coast of the US, but I ended up visiting a very small part of the West Coast – San Diego, California. I loved it so much I just had to come back and explore this region for 20 days.

The US is such a massive country with so much to offer its visitors and locals. Due to its diverse, magnificent attractions, you can easily explore different worlds featuring various natural wonders on the same day.

At the same time, the west coast of the US has one of the most fantastic national parks to explore. Road-tripping in the US is one of the best ways to explore the country, especially on the west coast.

This guide will help you plan two different ways to explore the west coast of the US. You can explore it by road or by taking a mixture of driving and taking domestic flights. Renting a car in the US is pretty easy. Most cars can be picked up at the airport, and finding flights should not be a big problem.

These itineraries for 3 weeks on West Coast USA are suitable for travelling in any country, but good planning is required if you want to go during the peak season. June until August is the busiest month for travelling around the US.

Planning a trip to a new place you have never been to can be challenging. The best way to start is, to begin with something easy such as deciding the places you really want to see and the time of the year you want to go. Here are things to help you plan and write your trip itinerary.

Getting around

We highly recommend you rent a car which is very easy to do in the US. It will give you the freedom to go anytime and anywhere. Don’t worry about spending too much time in the car.

You can also chop up the entire 3 weeks on west coast USA by travelling to the places near each other by car and then further by air.

You can also use public transportation such as a bus or train; although cheaper, they can be unreliable and not very flexible. Again, if you plan to travel during peak season, make sure to book your flight and car in advance, especially if you want a specific vehicle, such as a camping van or an electric one.

Best time to go

The best time to visit the west coast of the US depends on the activity you want to do. Many places for hiking and camping here are great to do during spring, summer, and even autumn. But if you want to go skiing, you definitely have to plan a trip for winter.

  • Peak Season: Summer (June to August) is peak season, offering warm weather perfect for beaches in California and outdoor activities across the region. Expect larger crowds and higher prices, especially in tourist hotspots.

  • Rainy Season: In the Pacific Northwest (Washington and Oregon), the rainy season runs from late fall through early spring (November to March). This period brings cooler temperatures and frequent rain, but fewer tourists and lush landscapes.

  • Winter Season: Winter (December to February) is mild in California, ideal for those seeking cooler but not freezing temperatures. In contrast, the Pacific Northwest experiences cold and wet weather, which can be a great time for snow sports in the mountains.
  • The shoulder seasons, spring (March to May) and fall (September to November). These times offer pleasant temperatures, blooming landscapes in the spring, and colourful foliage in the fall, making them excellent for exploring the diverse landscapes and cities of the West Coast.


The US have one of the strictest visa policies in the world. Only a limited number of nationalities can enter the country and enjoy visa-free. If your passport is from Europe, Canada, some parts of Latin America, South Korea, Japan, Singapore, New Zealand, and Australia, you can enter and travel around the US without applying for a visa for six months maximum.

Those nationalities can enter and stay in the US for 90 to 180 days but are still required to get an ESTA in advance. Even after applying for a tourist visa, you can stay in the country for up to 6 months. That is plenty of time for your 3-week in the USA holiday.

It’s no secret that medical services are super expensive here. Thus, getting insurance is worth every penny. You also don’t want the immigration officer to deny you entry if they find out you don’t have insurance valid for the US.

Other travel tips

While planning your holiday, these websites and tools will help you book everything. From flight, accommodations, car rental, and even buying travel insurance.

These are the sites I always use for my trips. I love how many of these travel services have a flexible cancellation policy that allows me to snatch reasonable prices even though I’m not sure about being able to make the trip.

If it’s your first time in the US, we have 3 weeks in the US itinerary that takes you to the most popular places across the entire country.

Los Angeles

Los Angeles is also renowned as the “City of Angels” and the location of celebrity-owned mansions. It is a great starting point on your 20 days on West Coast USA trip since it is home to incredible beaches, regional art, and varied culture that every traveller should see.

Besides theme parks, Los Angeles is also known for its unique surfing spots. Head to 27th St Manhattan Beach or the famous Venice Beach for some great waves. You can also explore your way around Los Angeles through its food culture.

There are many places to eat in LA if you are looking for Instagrammable spots, quick bites, or splurge at fancy restaurants. Los Angeles is for you if you’re looking for glamour and excitement.

Rather than exploring the city with public transportation, book a rental car to make the most of your trip, and consult with the rental company if it’s possible to drop off the car in Seattle or other airports you plan to stop and switch to taking a flight. You can even go on a 26-mile day trip to Disneyland on I-5 South which takes around 30 minutes.

Las Vegas

Las Vegas is referred to as the ultimate playground and attracts a wide range of tourists who want to experience its entertainment, gastronomy, and nightlife scene. There are various options available for people of all ages to enjoy.

From incredible museums, performances, and interactive games to renowned hotels and restaurants, Vegas offers it all. But do you know there are many things to do in Vegas besides gambling?

This includes exploring Freemont Street, Downtown Container Park, and even a day trip to the Grand Canyon.

Depending on your route, expect to allocate at least 4 hrs on the road from Los Angeles to Vegas.  The shortest and most common way, the I-15 N, takes roughly 4 hrs and 15 mins to complete across a distance of 270 miles (425 km). You’ll enjoy the famous drive between Barstow and Victorville while travelling along this route.

You can also book a bus from Los Angeles to Las Vegas. That will take 5 hr and 10 mins. There are non-stop flights between these two cities that will only take 1 hr and 20 mins.

Things to do in Las Vegas

TIP: If you want to save time, you can also visit the Grand Canyon from Las Vegas by booking a group tour or helicopter tour.

Grand Canyon

Tourists frequently visit the Grand Canyon due to its timeless beauty, which was made possible by untouched nature. In addition, the canyon itself provides a close-up view of the fascinating geological features, the array of rocks, and the numerous desert habitats that are otherwise impossible to witness without travelling to the location.

You can do many activities, including hiking, horseback riding, rafting, swimming, or just taking a leisurely stroll. Spend a night inside the Grand Canyon Village, on Grand Canyon National Park’s South Rim, where most tourists head while exploring the Canyon.

While there are various places to stay overnight, the most renowned sought-after is El Tovar, which sits directly on the rim of the Canyon and offers an incredible view. Make sure to book ahead of time for cheaper rates.

Grand Canyon West Rim is the nearest entry point, about 128 miles (206 km) or roughly a 2 hr 30 mins drive from Las Vegas. The route passes through areas of Arizona as well as notable locations, including Boulder City, Hoover Dam, and Lake Mead. 

Taking a bus or flying to the Grand Canyon can be tricky. If you want to fly to Flagstaff (the town where the Gran Canyon is), you’ll have to take a flight to Flagstaff, which means you need to connect, which could take 3 to 4 hours. You can also fly to Phoenix Airport, requiring you to drive for nearly 5 hours to the Grand Canyon.

If you’re not driving a rented vehicle, you can take a bus from Las Vegas to Flagstaff. That will take 6 hr and 40 mins. From Flagstaff, you can rent a car to explore the Grand Canyon or take a bus/train.

Zion National Park is home to 68 different species of mammals, ranging from bighorn sheep to the little kangaroo rat. Mule deer, foxes, rock squirrels, bighorn sheep, and bats are the most frequently sighted animals. 

Springdale, just outside Zion National Park and set against one of the most spectacular mountain backdrops you will ever encounter, is the place to book accommodations for your Zion visit.

This area is home to locally owned and operated hotels, bed and breakfasts, art galleries, restaurants, markets, tour guides, gift shops, and many more. Your road trip starts in Desert View, near the park’s Eastern border.

Leave the Grand Canyon through the east entrance and take Arizona State Route 64 toward Highway 89 for about 30 miles (48 km). With a distance of 252 miles (404.5 km), it takes around 5 hrs and 40 mins to travel directly from Grand Canyon to Zion National Park.

No buses will directly connect you from the Grand Canyon/Flagstaff to Zion National Park. But you can fly from Flagstaff to St George Regional Airport. From there, you can rent a vehicle to explore Zion National Park for the day since it’s only an hour’s drive from the airport.

Although there aren’t many tours available here, many camping options exist.

While Craters of the Moon may appear barren, it is home to small desert rodents, including bobcats, bats, foxes, owls, mountain lions, and nighthawks. The park’s animals will be active depending on the weather and the time of the day. 

If you’re looking for a place to stay, head over to Pocatello, the largest city in Southeast Idaho. It is an excellent starting point due to its convenient location at Highways 15 and 86 junction. To secure a slot near the tourist centre, make sure to plan your stay accordingly.!

The direct drive from Salt Lake City to Craters of the Moon National Monument takes around 3 hr 4 mins through the US-26 W and I-15 N, covering a distance of 345 miles (555 km).

3 weeks on west coast USA is incomplete without visiting Yellowstone National Park. Yellowstone is an active volcano that many scientists always keep an eye on for the possibility of an eruption. Every year, there are 700-3,000 earthquakes caused by the volcano.
