The Legendary Hawaiian Crater Hike On Oahu Is Short, Steep, And Absolutely Stunning

Last year, nearly 10 million people made the trek to the gorgeous state of Hawaii. And out of that number, a large percentage visited Oahu. No wonder the island is known as "the Gathering Place." Maybe it's because there are so many outdoor adventures to experience, maybe it's because there are so many sights to see, or maybe it's because Oahu is the most budget-friendly island in Hawaii. There are lots of reasons visitors decide that the third-largest Hawaiian island is the perfect island for a first-time visit.

But one of the most iconic attractions on the island is Lēʻahi (Hawaiian for "brow of the tuna") also known as Diamond Head State Monument. This 475-acre legendary landmark is a giant crater that lends its distinct and looming silhouette to the skyline on the east side of Waikiki. Those willing to make the short but steep hike up the summit trail will be treated to sweeping views of Honolulu and Waikiki Beach.

Lēʻahi (Diamond Head) was created by a volcanic explosion about 300,000 years ago. Once the dust settled, sparkling calcite crystals formed around the volcanic cone. When British soldiers arrived in the 19th century, they thought they'd discovered diamonds and were no doubt disappointed. Nevertheless, they named the crater Diamond Head. By 1908, the summit trail was constructed as part of the island's coastal defense system.

Although the trail is just under a mile long, it includes 560 feet of elevation gain, two flights of stairs, two tunnels, and a spiral staircase. It's not an easy hike. Once you reach the highest elevation (761 feet), you'll enter the Fire Control Station built in 1911, then continue along the trail down 82 stairs to the military bunkers built along the crater's rim. Finally, make your way to the lookout point where you can see the lighthouse built in 1917, miles of southeastern Oahu coastline, and (depending on the time of year) maybe even a few humpback whales. The entire round-trip hike takes about two hours plus extra time for the photo ops.

While this is one of the best outdoor activities to do in Hawaii, it's a steep hike, so good walking shoes are a must. Also, don't forget a hat and sunscreen to protect your skin from that intense island sun. We know you'd love to bring your fur babies along, but only service animals are allowed on the trail. Residents with a valid Hawaii State ID can visit without any reservations or parking fees. However, reservations are required for non-residents, so be sure to visit the Hawaii State Parks website to reserve your spot before you go. 

Non-residents pay a $5 per person entry fee and a $10 parking fee (children under 3 years old visit free). If you want to learn more about the history of Lēʻahi, be sure to take advantage of the self-guided audio tour for an additional $7.99 per person. The park is open every day from 6:00 a.m. until the gates close at 6:00 p.m. (minus Christmas Day and New Year's Day).
