The beautiful state of Hawaii is the last state to be part of the US. The state is made of islands from many volcanoes around the Pacific; many of these younger volcanoes remain active.

But today, Hawaii is known for its pristine beaches, golden sunset, fantastic surfing, amazing hikes, and unique culture. Since it’s part of the US, many tourists here are US Americans. However, its beauty attracts many foreign visitors from all over the world.

From the rhythmic hula dances to the mesmerizing call of ancient chants, it promises more than just postcard-perfect beaches. Walk through lush rainforests, scale volcanic landscapes, or simply let the spirit of ‘Aloha’ wash over you.

This 3 weeks in Hawaii itinerary will help you plan, visualise, and create a travel guide that is suitable for you and features activities that you love.

When is the best time to go to Hawaii

Hawaii, with its year-round tropical allure, is always a sought-after destination. But since it’s a rather expensive destination, I recommend you consider travelling during the shoulder season.

Peak Season (Mid-December to Mid-April): The Hawaiian Islands see the most visitors during these months. With cold winters elsewhere, many flock to Hawaii’s warm embrace. Expect higher prices and crowded attractions, but also reliably gorgeous weather.

Shoulder Season (Late April to Early June and September to Mid-December): This is the best time to travel to Hawaii. The crowds are fewer, and prices are often more affordable than peak season. The weather remains mostly pleasant, although there’s a slightly higher chance of rain.

Rainy Season (November to March): While Hawaii is an enticing destination throughout the year, it does experience more rain during these months. However, showers are often brief and localized.

Typhoon Season: It’s worth noting that Hawaii rarely sees typhoons, a weather phenomenon more common in the Western Pacific. While hurricanes can occur, they’re infrequent, with the most active period being from June to November.

Are 3 weeks enough for Hawaii

Yes. 20 days in Hawaii is plenty of time. You can visit all the islands; just be prepared that it won’t be a budget-friendly trip. Hawaii is an expensive destination, and you need to fly from island to island to save time. By visiting during the shoulder months, you could save some money as well.

What to pack

When heading to Hawaii, the essentials are a reef-safe sunscreen to protect your skin and the delicate marine ecosystems, comfortable walking shoes for exploring diverse terrains, and a swimsuit to plunge into the Pacific at a moment’s notice.

It’s also essential to bring water activity items such as snorkelling gear and water shoes if you don’t like the idea of renting one or planning to visit during peak season when rental places could run out.

You should check out our packing list for a 3-week trip and our summer packing list for a 20-day vacation.

How to get around

Navigating Hawaii’s diverse islands requires a mix of transportation. Inter-island flights are the quickest and most efficient for island-hopping, with major carriers like Hawaiian Airlines connecting the main islands.

Once on an island, renting a car is advisable for flexibility and accessing remote areas. Public buses and shuttles are available for short distances, particularly in urban regions like Honolulu.

Additionally, ferries operate between select islands, offering a scenic alternative. At the same time, ride-hailing apps such as Uber, Lyft, and Holoholo are popular ones to use around the city.

Language and currency

Hawaii is unique in its language. While English is the predominant language and is spoken by nearly everyone, Hawaiian is also an official state language. Tourists can easily get around using English in all parts of the islands.

Additionally, due to its diverse population and tourism influence, you’ll hear other languages spoken in tourist-heavy areas, especially Japanese. The term “Aloha” embodies both a greeting and a way of life, reflecting the islands’ warmth and spirit.

Knowing a few Hawaiian phrases, like “Mahalo” (thank you), can enrich your experience and resonate with the locals.

Hawaii uses the US Dollar ($, USD) as its official currency. While major credit and debit cards are widely accepted in hotels, restaurants, and most businesses, carrying some cash for smaller establishments, local markets, or remote areas is advisable.

ATMs are readily available across the islands. Although card payments are predominant in many areas, cash ensures a seamless experience, especially for tipping or exploring off-the-beaten-path locations.

Tipping in Hawaii

Tipping is a massive part of US American culture and is expected in the service and tourism industry, such as hotels, restaurants, bars, and even ferry ports.

The general tipping is around 20% to 25% of your total bill. But let’s say for ordering a drink at a bar $1 to $2 is what is expected. The same is true for porters or bellhops, where $1 to $2 per bag.

While tipping is optional, due to US laws, many workers in the service industry are making a lot less than the national minimum wage. This forces these workers to rely on tips as their main source of income.

Average travel cost for 20 days in Hawaii

Vacationing in Hawaii can cater to various budgets. However, costs can vary based on travel choices, seasons, and personal preferences. Here’s a general breakdown:

  • Affordable: Budget travellers might spend $80-$120 per day or $1,600 to $2,400 for 20 days. This includes staying in hostels or budget hotels, eating at local eateries or food trucks, using public transport, and enjoying free or low-cost attractions like beaches and hikes.
  • Mid-range: A mid-range traveller may spend $150-$350 daily or $3,000 to $7,000 for 3 weeks. This entails staying in 3 to 4-star hotels or vacation rentals, dining in mid-tier restaurants, renting a car, and participating in paid activities like guided tours or surf lessons.
  • Luxury: For a luxury experience, expect to spend $500-$1000+ per day or $10,000 and up for 20 days. This includes staying in 5-star resorts, dining at gourmet restaurants, private tours, spa treatments, helicopter rides, and more personalized experiences.

Remember, inter-island flights or special activities can add to these costs. Planning and booking in advance often result in savings.

Visa

Since Hawaii is part of the US, its visa policy is aligned with it. Foreign visitors with passports issued by Canada, Argentina, French Guiania, the EU, the UK, Japan, Australia, Malaysia, New Zealand, South Korea, Taiwan, and Singapore can travel to the US between 90 days and 180 days.

The rest of the world must apply for a US tourist visa from the nearest US Embassy in advance. I highly recommend you get a travel insurance for the US especially if you plan to do thrilling activities such as paragliding, riding planes, hiking, diving, and more.

Other travel tips

Hawaii is such a popular destination both to locals and foreigners, especially during the summer months (June to August) and winter (November to February). This means that you must book your hotels and car rental in advance if you plan to visit during these months.
