Beaches Near Diamond Head

About Diamond Head

Diamond Head (Lēʻahi) is the iconic volcanic crater that defines the eastern skyline of Waikiki, rising 760 feet above the coast. The short but steep hike to the summit is one of Oʻahu's most popular attractions, rewarding climbers with panoramic views from Koko Head to the Waianae Range.

The coast here transitions from the sandy shores of Waikiki's eastern end to the rocky, tide-pool-rich stretches of the Diamond Head coastline, eventually leading to the premier snorkeling at Hanauma Bay around the next headland.

From Diamond Head crater, Kaimana Beach is a short walk or drive west along Kalakaua Avenue. Diamond Head Beach is directly below the crater on the south side, accessed via a path near the lighthouse. For Hanauma Bay, drive east on Kalanianaole Highway (about 15 minutes) and book reservations in advance. Kailua Beach requires crossing the Koʻolau mountains via Pali Highway (Hwy 61), about 25 minutes.

Planning consideration: Kaimana Beach (check current notices). Best snorkeling: Hanauma Bay (reservations required, marine conservation district). Best beach overall: Kailua Beach (world-class, over the Pali). Most unique: Diamond Head Beach (tide pools, surf breaks, rocky coastline).

• Wait 72 hours after rain stops before entering the water
• Avoid brown or murky water regardless of whether an advisory is posted
• Best rain-resistant option: Diamond Head Beach (South side of crater) — generally clearer after rain due to geography
