Kalani MillerSun, Sand & Sea: Lanai's Pristine Coastline
Hulopoe Bay
Fronting the Four Seasons Resort, Hulopoe Bay is Lanai's premier beach and a protected Marine Life Conservation District. Its crescent of white sand meets calm, crystal-clear water. This makes it perfect for swimming and snorkeling, especially in summer. The reef is vibrant with marine life, including large parrotfish, schools of convict tang, sea turtles, and occasionally pods of spinner dolphins that come to rest in the bay. The beach park is open to the public and has excellent facilities, including restrooms, picnic tables, and showers.
Local Tip: Having spent many hours in these waters, my personal tip for snorkeling at Hulopoe Bay is to start on the left (east) side of the bay, where the coral is most vibrant. The real treasure is found at low tide in the large volcanic tide pools. These pools are precious nurseries for the reef, teeming with small fish, sea stars, and ʻopihi (limpets). Please look, but do not touch. From the tide pools, a short 15-minute hike leads you to the legendary Puʻu Pehe (Sweetheart Rock), a stunning sea stack that is especially beautiful at sunset.
The Legend of Puʻu Pehe
The legend of Puʻu Pehe tells of a young warrior from Lanai who fell deeply in love with a beautiful woman from a rival island. Fearing that others might steal her away, he hid her in a sea cave below the rock stack. One day, while he was away, a storm filled the cave with water and she drowned. Overcome with grief, he carried her body to the top of the rock stack, buried her there, and then leaped to his death into the churning sea below. Today, the rock stands as a monument to their tragic love story, and locals still leave flowers there in their memory.
Kaiolohia (Shipwreck Beach)
On the windswept northern coast lies Kaiolohia, an 8-mile stretch of beach known for the many vessels that have met their end in its treacherous, shallow channel. This is a place for exploration, beachcombing, and photography. It is absolutely not a place for swimming. The currents are strong and the waters are rocky and dangerous.
The most prominent feature is the ghostly, rusted hull of a WWII-era vessel grounded on the reef. Many mistakenly call it a Liberty Ship, but maritime historians have identified it as a concrete-hulled navy fuel tanker, the YOGN-42. Access requires a 4x4, and you should park your vehicle once the road opens up at the sandy area to avoid getting stuck. From there, a short hike along the coast reveals not only the wreck but also the Pōʻaiwa petroglyphs, ancient rock carvings etched into boulders about 200 yards up a trail from the beach.
The Pōʻaiwa Petroglyphs
These petroglyphs represent some of the oldest human artwork in Hawaii. The figures carved into the dark volcanic rock include representations of humans, dogs, and various symbols whose meanings have been lost to time. Archaeologists believe they were created by Native Hawaiian travelers who used this area as a temporary camp while fishing or gathering resources from the sea.
Walking along Shipwreck Beach, you'll find all manner of debris washed ashore by the relentless trade winds and currents. Glass fishing floats from Japan, pieces of driftwood sculpted by salt and sand, and shells from distant reefs all tell stories of the ocean's vast reach. This beachcombing can be rewarding, but remember that this is still a fragile ecosystem. Take only photos and memories, leaving everything else for future visitors to discover.
Polihua Beach
For those seeking ultimate solitude, Polihua Beach on Lanai's remote northwest coast offers one of Hawaii's most pristine and undeveloped stretches of sand. The name "Polihua" means "eggs in bosom," referring to the green sea turtles that once nested here in great numbers. While turtle nesting has decreased due to various environmental pressures, the beach remains a spectacular example of untouched Hawaiian coastline.
The journey to Polihua is an adventure itself, requiring a challenging 45-minute drive on rough 4x4 roads through the island's arid interior. The route passes through former pineapple fields and offers sweeping views of Molokaʻi across the Kalohi Channel. Once you arrive, you'll likely find yourself alone on a vast expanse of white sand backed by low sand dunes and native coastal vegetation.
Safety Warning: Like Shipwreck Beach, Polihua is not suitable for swimming due to strong currents and rough surf. However, it's perfect for solitary walks, photography, and simply experiencing the raw power of the Pacific Ocean. On clear days, the views of Molokaʻi's towering sea cliffs are breathtaking, and you can sometimes spot the island of Oahu in the far distance.
