Should you visit Kauai or Oahu?

Which city should you visit? Read on to compare the prices of travel for Kauai and Oahu. We’ll break down costs for accommodation, food, transportation and more to help you learn more about these two destinations. Then, you can figure out if either of these two places are accessible based on your travel budget. So, let's dig into it.


Hawaii is certainly a bucket list destination, but what if you want to do it without being surrounded by tourists? You want the adventure of the land of volcanoes and less of the kids in water wings. Then Kaua'i is the island for you.

Kaua'i, or the "garden island," is full of tropical forests, little villages and even more laid back lifestyle if you can imagine. It's a smaller island at 560 square miles with a population of only 68,000.

With more coastline miles than any other island, Kaua'i is the result of massive erosion forming awe-inspiring sights like the Waimea Canyon and Na Pali Coast. The island experiences more rainfall every year keeping it lush and green all year.

You'll feel like you've walked into another world in Kaua'i. Because of height restrictions, this island's buildings are no taller than the coconut trees. So if you're looking for an escape from civilization, you'll want to head straight for Kaua'i.


Hawaii is the epitome of paradise, and at the heart of paradise is the island of O'ahu (or Oahu). While it's only the third largest of the Hawaiian islands, O'ahu, or "the gathering place," is the most populous in the state with approximately 976,000 people calling O'ahu home, many of which live in the capital city of Honolulu.
