You are currently viewing Hawaii’s busiest islands

Thinking about a vacation on one of Hawaii’s islands? Wondering which island is most crowded? You have come to the right place. In this blog we explain which island in Hawaii is the best to travel to by looking at the number of fellow tourists. We have sourced data from Hawaii’s official Tourism Authority and combined that with some of our own data and insights.

In this post we look at activities on the island as well the number of tourists traveling to each of those islands per year. Combined with some other datapoints such as size of the island, number of hotels and more, we will explain to you which Hawaii island to visit. Data by Hawaii’s Tourism Authority showed that in 2019, 10,2 million tourists arrived in Hawaii by air. On top of that the islands welcomed about 142k cruise passengers. Most of those 10 million tourists visit Oahu and/or Maui. These two islands are the busiest islands in Hawaii.

2023 update: Visitor numbers to Hawaii have almost completely recovered from COVID-19. In the summer of 2022, visitors arrivals were already at 92.4 percent of pre covid levels. For this overview we use 2019 numbers to give the most realistic overview of Hawaii’s busiest islands.

The majority of tourists, about 7 million out of 10 million tourists in 2019, in Hawaii come from the United States. Especially those living in the Western Part of the country know their way to the islands. Foreign visits are mainly coming from Japan (1.5 million) followed by Canada (548k).

1. Oahu

Oahu is by far the most visited island in Hawaii. Before COVID hit, the island welcomed over 6 million visitors per year (2019 data). It also makes sense if you think about it. Oahu is home to Hawaii’s most famous tourist attractions. Not only can you find the state’s capital Honolulu on Oahu, you can also visit Pearl Harbor as well as the famous Waikiki beach.

Best time to visit Oahu:

April to June & September to early December

Oahu is also Hawaii’s cheapest island to visit. The island has the most hotels which leads to increased competition. The island also has the most restaurants, activities and bars. Due to the ease of accessibility, things don’t have to go onto an extra boat or airplane which reduces the purchasing costs for businesses . That means that prices are more under pressure in Oahu than elsewhere. More competition in combination with lower costs for the industry lead to lower prices for us as tourists making Hawaii more accessible. On top of that, you can fly directly to Oahu (Honolulu) from many destinations on the US mainland. Without a stopover, this means less flying. As a result, Oahu (together with Maui) is the cheapest island in Hawaii to fly to.

It is not just the abundance of activities or the relatively low costs that make Oahu a perfect island to visit. The island has a very active and fun nightlife and is incredibly diverse. This diversity leads to a delicious cuisine and vibrant social atmosphere. Like all other islands Oahu is home to beautiful beaches and bays. The north shore of the island is a surfer’s paradise known for its perfect waves.

The best time to visit Oahu is during one of the two shoulder seasons. We recommend visiting Oahu from April to June or September to early December. The busiest months are July and August as well as during the holiday season in late December.

Before COVID hit, Maui has seen a steady flow of tourists. In 2019, the island registered about 3 million visitors. While the numbers are well beyond those of Ohau, these 3 million visitors make Maui, Hawaii’s second most frequented visited island. Maui is also Hawaii’s second largest island in size and attracts lots of tourists that come to watch whales, especially during the winter months.

The weather on Hawaii’s Big Island is stable around the year. The average temperature and average precipitation don’t fluctuate too much throughout the year. What does fluctuate is the number of visitors. Most visitors visit the Big Island in summer, during Spring Break and around the Christmas season. Outside those peak seasons, each month is good for a visit. According to our data, the best months to visit Hawaii’s Big Island are February, April, May and September to November when prices for hotel rooms also drop.
