We’ll also talk about safety tips, the best times to visit, and how to respect these fragile ecosystems. So, get ready to explore the contrasting beauty of Hawaii’s volcanic landscapes!
How Black Sand Beaches Are Made: Nature’s Artistic Eruption
The story behind a black sand beach starts with a volcano. Specifically, basaltic lava, which is rich in iron and magnesium. When this molten rock flows into the ocean, the rapid cooling causes it to shatter into fine fragments. This process is known as littoral explosions or hyaloclastite formation. Over time, the ocean waves and currents grind these fragments down further, creating the fine, black sand that characterizes these beaches. The black color comes from the basalt rock itself.
There isn’t just one way for this to happen, though. Another process involves lava tubes. The Big Island of Hawai’i, with its active volcanoes, is where you’ll see this most prominently. Molten lava flows through underground tubes, eventually reaching the coastline. As it pours into the ocean, the same shattering and grinding process occurs, creating black sand. It’s a slow, constant process, and the texture of the sand can vary, from coarse and gravelly to smooth and fine.
Punalu’u Black Sand Beach (Big Island): Turtle Haven
Located on the southeastern coast of the Big Island, Punalu’u Black Sand Beach is perhaps the most famous black sand beach in Hawaii. It’s renowned for its frequent Hawaiian green sea turtle (honu) sightings. These gentle creatures bask in the sun on the warm black sand, making it a truly special experience. While observing them is a treat, remember to maintain a respectful distance of at least 10 feet (3 meters), as they are protected under the Endangered Species Act.
Getting There: Punalu’u is about an hour’s drive south of Kailua-Kona (70 miles) and about an hour and 45 minutes south of Hilo (50 miles). Take Highway 11, and you’ll see signs for Punalu’u Black Sand Beach. There is ample parking available.
What to Do: Besides turtle watching, you can enjoy picnicking (there are picnic tables available) and explore the small freshwater ponds located inland from the beach. These ponds, fed by underground springs, were historically used for growing taro.
Things to Know: The black sand gets very hot under the Hawaiian sun, so it’s advisable to wear footwear, especially during midday. Swimming isn’t the best here due to strong currents and rocky conditions, but it’s beautiful to look at. Always heed the warning signs posted regarding ocean conditions. The sand itself can be coarse, and it’s not ideal for building sandcastles, really. This is more a place for appreciating the view and the wildlife.
Cost: There is no entrance fee to access Punalu’u Black Sand Beach. Parking is free.
Waianapanapa State Park (Maui): Coastal Magic
Waianapanapa State Park, near Hana on Maui’s eastern coast, is an iconic destination, famed for its stunning black sand beach (Honokalani Beach), sea caves, blowholes, and coastal hiking trails. It’s a must-see stop along the Road to Hana, and its unique features offer a memorable experience.
Getting There: Waianapanapa State Park is located just before the town of Hana on the Road to Hana. From Kahului Airport (OGG), it’s about a 2-3 hour drive, depending on traffic and how often you stop along the way. Pre-booking is now required.
According to the official website , “All visitors, including Hawaii residents, must make reservations online up to 30 days in advance.”
Reservations and Costs: As of spring 2024, reservations are mandatory. This helps manage the crowds and protect the fragile ecosystem. The cost is $5 per vehicle for parking and $10 per person for entry (children under 3 are free). Reservations can be made online at the Hawaii State Parks website. Book well in advance, especially if you’re traveling during peak season.
What to Do:
Explore Honokalani Beach: This is the black sand beach within the park. The contrast of the black sand against the turquoise water is incredibly striking.
Hike the Coastal Trails: The park offers several hiking trails that wind along the rugged coastline. These trails provide breathtaking views of the ocean, cliffs, and blowholes. Check to see the condition of each trail before heading in, to be sure that conditions are acceptable.
Visit the Sea Caves: Waianapanapa means “glistening water” in Hawaiian, and the park’s sea caves live up to the name. The caves are accessible from the beach and offer a glimpse into the power of the ocean. During certain times of the year, you might even see red shrimp in the cave pools, a natural phenomenon.
Check out the Blowhole: The park includes some impressive blowholes which shoot water into the air when waves crash against the rocks.
Camping: Tent camping is available in the park (permit required).
Things to Know: The Road to Hana is a long and winding drive, so allow a full day for the trip. Be prepared for rain, as the Hana area is known for its frequent showers. Wear comfortable shoes for hiking. The black sand can get very hot, so use footwear. Swimming at Honokalani Beach can be dangerous due to strong currents and potentially rough surf, so exercise caution and heed any posted warnings. The park can get crowded, especially mid-day, so an early start is recommended.
Oneuli Beach (Maui): A Hidden Gem
Oneuli Beach, located in South Maui near the Makena area, is a lesser-known black sand beach that offers a more secluded experience compared to Waianapanapa. The name “Oneuli” translates to “dark sands” in Hawaiian, which accurately describes the beach’s black volcanic sand. It’s a great spot for snorkeling and diving, as the waters are usually calm and clear.
Getting There: To reach Oneuli Beach, head south on Makena Road past the turnoff for Big Beach (Makena Beach). You’ll see a dirt road on the left. Follow that road for a short distance. The road can be a bit bumpy, so drive slowly. Look for the parking area near the beach access point. High clearance vehicles are generally recommended but are not always required. You can also walk from the south end of Big Beach, but this requires navigating some rocky terrain.
What to Do:
Snorkeling and Diving: Oneuli Beach is a popular spot for snorkeling and diving because of the abundance of marine life. The underwater visibility is often excellent. Coral reefs and other rock formations provide habitats for lots of fish, sea turtles, and other marine creatures.
Relaxing on the Beach: The black sand provides a unique setting for sunbathing and relaxation. As it is less crowded than other beaches, you can spread out and enjoy the peace.
Photography: The dramatic contrast of the black sand against the blue ocean and sky makes Oneuli Beach a favorite spot for photographers. The clear water and interesting rock formations also offer great photo opportunities.
Things to Know: There are no facilities at Oneuli Beach, meaning no restrooms, showers, or lifeguards. So, come prepared with water, sunscreen, snacks, and anything else you might need for the day. The sun can be intense, so wear sunscreen and a hat. The beach is relatively small and can disappear completely at high tide, so check the tide charts before you go. The dirt road leading to the beach can be rough, so drive slowly and carefully.
Cost: Access to Oneuli Beach is free. Parking is also free but limited.
Kehena Black Sand Beach (Big Island): Seclusion and Swimming
Kehena Beach, also known as Dolphin Beach, is a secluded black sand beach located on the Puna coast of the Big Island. It’s known for its relaxed, clothing-optional atmosphere and its frequent dolphin sightings. It’s a bit more off the beaten path compared to Punalu’u, but is a charming beach to explore.

Respecting Hawaii’s Black Sand Beaches: Leave No Trace
Hawaii’s black sand beaches are fragile ecosystems, and it’s important to treat them with respect. Here are some tips for responsible tourism:
- Don’t Take Sand: Removing sand from any Hawaiian beach is illegal and can have significant environmental consequences. The sand is a natural resource, and its removal contributes to erosion and habitat loss. While a seemingly small amount may not seem like much, every handful taken contributes to the problem.
- Respect Wildlife: Keep a safe distance from sea turtles and other wildlife. These animals are protected by law, and disturbing them can result in fines and penalties. Don’t feed the animals, as this can alter their natural behaviors and make them dependent on humans.
- Stay on Marked Trails: When hiking, stick to marked trails to avoid damaging fragile vegetation and soil. Going off-trail can contribute to erosion and disrupt wildlife habitats.
- Pack Out What You Pack In: Don’t leave any trash behind. Bring a trash bag with you, and dispose of your waste properly. Even biodegradable items can take a long time to decompose and can still be harmful to wildlife.
- Use Reef-Safe Sunscreen: Regular sunscreen contains chemicals that can harm coral reefs. Choose reef-safe sunscreen that is free of oxybenzone and octinoxate.
- Be Mindful of Cultural Sites: Hawaii has a rich cultural history, and many beaches and coastal areas are considered sacred sites. Be respectful of these sites, and avoid disturbing any cultural artifacts or structures.
Additional Tips for Visiting Black Sand Beaches
- Wear Shoes: The black sand can get very hot under the sun, so wear sandals or shoes to protect your feet.
- Check the Weather: Weather conditions can change rapidly in Hawaii, so check the forecast before heading to the beach. Be prepared for rain, especially in areas like Hana.
- Bring Water and Snacks: Many black sand beaches are located in remote areas with limited facilities, so bring plenty of water and snacks with you.
- Be Aware of Ocean Conditions: The ocean can be unpredictable, with strong currents and high surf. Heed any posted warnings and avoid swimming in areas where it is not safe.
- Arrive Early: Popular black sand beaches can get crowded, so arrive early to secure a good spot.
The Best Time to Visit Hawaii’s Black Sand Beaches
Hawaii is beautiful year-round, but the best time to visit a particular black sand beach depends on your priorities.
For Warmest Weather: The summer months (May to September) are generally the warmest and driest in Hawaii. This is a good time to visit if you want to maximize your time in the sun. However, summer is also peak tourist season, so expect higher prices and more crowds.
For Whale Watching: If you want to see humpback whales, visit during the winter months (December to May). These magnificent creatures migrate to Hawaii’s warm waters to breed and give birth. Whale watching tours are available from many harbors on the islands.
For Fewer Crowds: The shoulder seasons (April-May and September-October) offer a good balance of pleasant weather and fewer crowds. You’ll still enjoy warm temperatures and sunshine, but you’ll avoid the peak season rush. Weekdays are also generally less crowded than weekends.
For Specific Activities: If you’re interested in surfing, the north shores of the islands typically have the best waves during the winter months. Snorkeling and diving are generally good year-round, but visibility may be better during the calmer summer months.
Safety First!
- Rip Currents: Be aware of rip currents, which are strong currents that can pull you away from shore. If you get caught in a rip current, don’t panic. Swim parallel to the shore until you are out of the current, then swim back to the beach.
- Shorebreak: Shorebreak is the breaking of waves directly on the shoreline. These waves can be powerful and can cause serious injuries if you are caught off guard. Exercise caution when entering and exiting the water.
- Sun Protection: The Hawaiian sun is intense, so protect yourself by wearing sunscreen, a hat, and sunglasses. Reapply sunscreen frequently, especially after swimming.
- Hydration: Drink plenty of water to stay hydrated, especially if you are hiking or spending time in the sun.
- First Aid: Bring a small first-aid kit with you, in case of minor injuries.
