In fact, you could spend a lifetime exploring Hawaii’s eight main islands and never run out of new places to discover. But, just in case you’re not sure where to start, I’ve compiled a list of 16 of the greatest hidden gems in Hawaii to start your bucket list – from the coast of Kauai to the summit of Mauna Kea on Hawaii Island.

From 1858 to 1879, the Haiku Mill was bustling with sugar cane production, but is now used for a slightly different purpose: serving as the backdrop for a variety of events, especially weddings. The mill is now home to an awe-inspiring mix of vine-draped ruins, French-inspired décor, and a unique ambiance.

Situated between Halona Point and the Halona Blowhole, this small rocky cove is perfectly picturesque, and has been featured in films like Pirates of the Caribbean and 50 First Dates. Despite its Hollywood fame, the only way to reach the stunning cove is via a rocky and slightly treacherous hike, so it is often pretty secluded.

Located more than 13,000 feet above sea level, near the summit of Hawaii Island’s Mauna Kea, is one of only a few lakes found throughout an island state known for its incredible beaches. It is also one of the smallest lakes in the country - measuring in at just 328 meters in diameter.

Situated off the coast of Windward is Oahu is a picturesque slice of paradise that is only accessible during low tide. The Kaneohe sandbar, located in the middle of Kaneohe Bay surrounded by the striking Ko’olau mountains, features crystalline turquoise waters, fine white sand, and plenty of fun. At high tide, you can comfortably stand waist-deep in the water, while at low tide, the sand is completely exposed.

Located just one mile past the famous Rainbow Falls on Wailuku River is Pe’epe’e Falls. Connected by a series of cascading waterfalls along columns that were formed from the slow cooling of basalt lava, these pools appear to be bubbling – almost as if they were boiling.

These volcanic formations are found on the edge of the Ritz’s golf course. The jagged, gray rocks were formed hundreds of years ago when wind gusts from the ocean forced lava to harden towards the sky. This intriguing scenery looks like something out of a science fiction or fantasy novel, does it not?

Editor's Note: You must travel through Lahaina, which was devastated by the 2023 fire, to reach the Dragon's Teeth. Please respect all state and local guidance as you travel through this area.

The geological formation is surrounded by high rock walls, and features an open ceiling to the sky. You can view the sea cave from above, or enter it on a boat tour. The light from the cave's open ceiling penetrates the water, and creates an ethereal blue hue that changes colors with the moving sun.

Located in Hanapepe, near Port Allen Harbor, is this incredible beach covered with millions of sea glass pebbles in brilliant hues of aqua, blue and brown. The glass found at this beach was mainly from broken bottles and auto glass that was dumped years ago, and then smoothed by time and ocean tides. The beach is pretty difficult to find, but it is heaven for lovers of sea glass.

Located on Oahu’s southeastern shore, just past Hanauma Bay, on Kalanaianaole Highway, is the Lanai Lookout, a seemingly average lookout point – that is, until you step over the man-made wall surrounding the parking lot and into the incredible lava formations below. Oh, and did we mention that on a clear day you can see Lanai, Molokai and Maui from the lookout?

We think these are simply some of the best hidden gems in Hawaii. Do you agree, or are there some other spots that you would add to this list? How many of these Hawaii hidden gems have you explored?
