Black Sand Beaches on the Big Island You Can’t Miss
If you're mapping out the best things to do on the Big Island, tracking down the best restaurants on the Big Island, or finding the best snorkeling spots on the Big Island, hitting a volcanic beach is a must. Staying at top-tier Hawaii hotels gives you the perfect base camp to explore these geologic wonders.
The island of Hawaii, affectionately known as the Big Island, is a place of raw, dramatic beauty. It's an island where the Earth is actively creating itself, thanks to the fiery, ongoing volcanic activity of Kilauea and Mauna Loa. Because of this continuous lifecycle of creation and erosion, the Big Island plays host to some of the most striking coastlines on Earth. Among its most iconic features are its jet-black sand beaches.
How Black Sand Beaches in Hawaii Are Created
But what turns this sand black, and why does the Big Island have so many of them? Unlike traditional white sand beaches, which are typically made of crushed coral, shells, and quartz over millions of years, black sand is born in an instant. When molten basaltic lava escapes from deep within the Earth and encounters the freezing Pacific Ocean, a violent thermal shock occurs.
The lava cools rapidly, shattering instantly into tiny fragments of volcanic glass and basalt rock. Over time, the relentless action of ocean waves breaks these fragments down even further, creating smooth, dark, and glistening sand. Because the Big Island is geologically the youngest island in the Hawaiian archipelago, its volcanic coastlines haven't yet been fully worn away or covered by coral growth. This creates a playground of dark coastlines waiting to be discovered.
If you're ready to experience the surreal feeling of jet-black sand between your toes, pack your camera and your water shoes. Here are the eight best black sand beach Big Island gems worth exploring on your next Hawaiian getaway.

1. Punaluʻu Black Sand Beach
When people picture a Hawaiian black sand beach, they're almost certainly picturing Punaluʻu. Located on the southeastern Kaʻū coast, this is easily the most famous, accessible, and photogenic black sand beach on the island. Framed by an iconic row of vibrant green coconut palms that directly contrast with the dark sand, Punaluʻu looks like a living postcard.
What truly sets Punaluʻu apart is its local residents: the honu (Hawaiian green sea turtles) and honuʻea (hawksbill turtles). These ancient marine creatures frequently crawl ashore to bask in the warm, sun-heated black sand. While it's incredibly tempting to get close, federal law mandates that you give these protected beauties a wide berth of at least 10 feet (3 meters). Swimming here can be tricky due to strong offshore currents and a rocky shoreline, but the beach offers great amenities, including restrooms, showers, pavilions, and a lifeguard on duty.
-
Pro Tip: For a unique historical detour, check out the Hokuloa Church sitting on the hill just above the beach. It's a quaint, open-air chapel constructed entirely out of local lava rock.
-
Getting There & Parking: Located off Highway 11 between the towns of Pāhala and Nāʻālehu. The turnoff is well-marked, and there's a large, paved parking lot directly next to the beach park that requires no hiking to access.

2. Richardson Ocean Park
If you're staying on the lush, rainy eastern side of the island near Hilo, Richardson Ocean Park is your absolute best bet for a quick beach trip. This local favorite isn't just an incredible visual destination; it's also one of the safest and best family-friendly options on this side of the island.
The sand here is a fascinating geological cocktail. It's a mixture of jet-black basalt fragments and green olivine crystals, giving the shoreline an almost iridescent, dark-olive hue under the direct midday sun. Because the bay is naturally protected by a sweeping seawall of jagged lava rock, the waters remain relatively calm, making it a fantastic spot for swimming and novice snorkeling. Freshwater springs bubble up from the ocean floor here, so you might notice cool pockets of water as you swim.
-
Pro Tip: Walk past the main beach area toward the tide pools. These calm, brackish pockets are natural nurseries for small marine life and a favored resting spot for sea turtles.
-
Getting There & Parking: Head down Kalanianaole Avenue along the Hilo coastline until the road nearly ends. Parking is free, but spots can fill up fast on weekends because it's a popular spot for Hilo locals. Full restroom facilities and lifeguards are available.
3. Pololū Valley Beach
For the travelers who want a massive dose of epic adventure alongside their coastal views, Pololū Valley Beach delivers on every front. Tucked away at the absolute northern end of Akoni Pule Highway (Highway 270), this beach sits at the mouth of a dramatic, eroded volcanic valley.
Before you even set foot on the sand, the view from the Pololū Valley Lookout will take your breath away. You'll see dramatic, sheer green cliffs plunging directly into a churning, dark blue ocean. To get down to the beach itself, you'll embark on a short but steep half-mile hike down the cliffside switchbacks. The trail drops about 400 feet in elevation, weaving through ironwood trees until you step out onto a sweeping expanse of fine, dark sand.
-
Pro Tip: Do not swim here. The rip currents and waves at Pololū are notoriously aggressive and dangerous, and there are no lifeguards. Instead, cross the beach to explore the beautiful ironwood forest or sit back and watch the wild waves crash against the offshore sea stacks.
-
Getting There & Parking: Drive to the very end of Highway 270. Parking at the actual lookout is extremely limited, with only about a dozen spots. Arrive before 9:00 AM to secure a space, or be prepared to park along the roadside and walk to the trailhead.
4. Isaac Hale Beach Park (Pohoiki)
Isaac Hale Beach Park is a living testament to the sheer power of Hawaii’s volcanic landscape. Located at Pohoiki Bay in the Puna district, this beach park was dramatically altered during the historic 2018 Kilauea eruption. Lava flows marched across the region, swallowing nearby communities and closing off parts of the coastline, but it ended up creating something beautiful right here: the island's newest black sand beach.
The lava flow stopped just short of destroying the park's boat ramp, instead piling up massive mounds of fresh basalt material that the ocean quickly ground down into a thick, coarse blanket of rich black sand and smooth river rocks. What makes this destination truly elite, however, are the Pohoiki Hot Springs. These thermal ocean ponds were naturally formed when underground lava heated the water table.
-
Pro Tip: Pack a towel and head just behind the beach into the tree line to find the main geothermal pool. The water is roughly 4 feet deep and hovers at a heavenly 100°F, creating a natural volcanic hot tub.
-
Getting There & Parking: Accessible via Highway 137 (the famous "Red Road"). The drive itself takes you directly over the hardened, massive 2018 lava fields, offering an incredible look at the island's terrain. There is a spacious gravel parking lot, portable restrooms, and lifeguards on site.
5. 49 Black Sand Beach (Honokaope Bay)
Most of the Big Island’s black sand destinations are clustered on the south and east coasts where the volcanoes are youngest. However, hidden away within the luxurious Mauna Lani resort community on the sunny Kohala Coast sits a true anomaly: 49 Black Sand Beach.
Nestled inside Honokaope Bay, this hidden gem features incredibly fine, soft black sand framed by striking, stark white calcium-carbonate rocks and upscale real estate. Because it's on the dry, sunny side of the island, the weather here is almost always perfect for sunbathing. The water inside the cove is crystal clear, making it a spectacular spot for underwater exploration.
-
Pro Tip: Because the beach is located inside a private gated residential community, you must request a public beach pass at the Mauna Lani security gate. Access is completely free, but there’s only a limited number of passes per day.
-
Getting There & Parking: Enter the Mauna Lani Resort area from Highway 19, follow the signs for the beach club or 49 Black Sand Beach, and present your ID at the gate. The dedicated public parking lot has restrooms and showers. Go early so you don't miss out on a parking pass.
6. Kehena Black Sand Beach
Kehena Beach is a spot that marches to the beat of its own drum. Tucked away along the Puna coast beneath steep, rocky cliffs, this beautiful crescent-shaped cove is renowned for its ultra-soft, powdery black sand, dramatic overhanging ironwood trees, and deeply bohemian, counterculture community vibe.
There's one major detail every traveler should know before heading down: Kehena is one of the few clothing-optional beaches in Hawaii. On any given day, you'll find locals sunbathing nude, playing music, and practicing yoga. If you visit on a Sunday, you'll get to experience the famous local drum circle that echoes through the cliffs. The trek down requires a quick, five-minute scramble down a steep, rocky path, so wear sturdy footwear.
-
Pro Tip: Keep your eyes glued to the horizon. Kehena translates to "the place where spinner dolphins play," and a pod of wild spinner dolphins frequently hangs out right in this bay, jumping and putting on a show for beachgoers.
-
Getting There & Parking: Located off Highway 137 near mile marker 19. Look for cars parked along the shoulder of the cliffside road. There's no official parking lot, so look for a safe pullout spot along the road.
7. Kaimū Black Sand Beach
If you want to understand the true cycle of destruction and rebirth on the Big Island, make a stop at Kaimū Black Sand Beach in Kalapana. In 1990, a massive, slow-moving lava flow from Kilauea completely inundated the historic town of Kalapana, burying the original Kaimū beach under 50 feet of solid rock.
Today, a new eco-path allows you to walk directly across that hardened, undulating lava field to reach the "New Kaimū Beach." It’s a surreal, 15-minute walk where you'll see small, bright green coconut palms sprouting directly out of the cracks in the dark stone—planted by locals to help bring life back to the coastline. At the end of the trail, you'll emerge onto a young, rugged beach where powerful waves crash violently against a brand-new shelf of dark sand.
-
Pro Tip: This beach is strictly for viewing and walking, not swimming. The surf here is incredibly dangerous, with no barrier to slow down the ocean swell. Stop by the nearby Uncle Robert's Awa Bar and Farmers Market afterward for some local food and live music.
-
Getting There & Parking: Take Highway 130 south to the very end in Kalapana. You'll find a parking area near the local vendor stands, where the trailhead begins.
8. Ka'u Forest Reserve
If you want to trade the crashing waves for a journey into the ancient, misty heart of the island, head inland to the Kaʻū Forest Reserve. Located on the southern slopes of Mauna Loa, this massive reserve is a hidden ecological crown jewel. While it isn't a beach, it's the very source of the island's raw beauty, offering a lush, primeval contrast to the stark lava fields down on the coastline.
Spanning more than 60,000 acres, this protected sanctuary is a thriving cloud forest filled with towering native ʻōhiʻa and koa trees, giant tree ferns, and some of the rarest birds on earth, like the vibrant red ʻapapane. The air up here is cool, crisp, and heavy with the scent of wild ginger. It's an incredible destination for adventurous hikers who want to experience the true wilderness of the island far away from the standard tourist tracks.
-
Pro Tip: This is a wild, undeveloped reserve with no paved paths, facilities, or cell service. You'll need to prepare as if you're going on a true expedition—bring a rain jacket (it showers frequently up here), plenty of water, and solid hiking boots. Keep an eye out for ancient stone structures hidden in the undergrowth, which serve as a reminder of the area's rich Native Hawaiian agricultural history.
-
Getting There & Parking: The reserve is accessible via several rough four-wheel-drive roads off Highway 11 near Nāʻālehu and Pāhala, such as Wood Valley Road. There are no official parking lots, so visitors typically park in clear, gravel pullouts near the forest boundary line. Make sure your vehicle has high clearance if you plan to drive past the paved sections.
Pro Tips for Visiting Volcanic Beaches
To ensure you have the best, safest experience exploring these unique coastlines, keep these expert tips in mind:
-
Leave the Sand Behind: It's illegal to remove black sand, rocks, or coral from any beach in Hawaii. Local legend says that taking volcanic rocks will incur the wrath of Pele, the volcano goddess. Keep the sand on the beach and take photos instead.
-
Prep for the "Oven Effect" and Sun Protection: Because black sand absorbs solar radiation rather than reflecting it, the ambient temperature just a few inches above the ground can feel significantly hotter than a traditional white-sand beach. Pack a high-quality umbrella for personal shade, bring plenty of extra drinking water to stay hydrated, and always apply reef-safe sunscreen. Traditional sunscreens contain chemicals like oxybenzone that are banned in Hawaii because they bleach and damage the fragile coral reefs you'll want to explore.
-
Check Ocean Conditions: Many of these coastlines feature steep drop-offs and open-ocean swells. Always check for warning signs or consult a lifeguard before entering the water.
-
Time Your Photographic Golden Hour: If you want your vacation photos to truly pop, timing is everything. The deep, rich tones of black sand can easily look washed out or overly dark under the harsh glare of a midday sun. Plan your visits for early morning or late afternoon. The low-angled golden light hits the volcanic grains perfectly, making the sand glisten like diamonds and providing a gorgeous contrast against the white sea foam and green palm trees.
-
Pack Water Shoes: Black sand retains heat significantly more than white sand. On a sunny afternoon, the ground can become hot enough to burn your feet. Always wear sturdy sandals or water shoes.
-
Watch for Changing Shoreline Footprint: Volcanic sand beaches are geologically fleeting and highly dynamic. Unlike older, stabilized coastlines, these beaches can change dramatically from month to month or even day to day based on rough winter swells and local currents. A wide expanse of soft sand you see in a photo online might be a bed of smooth basalt river rocks when you arrive. Embrace the island's ever-changing nature and always check local surf forecasts before you head out.
Visiting Hawaii's Dark Coastlines
Exploring the best black sand beaches on the Big Island is easily one of the most unforgettable, bucket-list activities you can experience when visiting the Aloha State. These volcanic wonders provide a front-row seat to the living, breathing geology of Hawaii, showcasing a dramatic contrast between stark, jet-black shorelines, lush emerald valleys, and vibrant turquoise waters.
From watching majestic sea turtles bask on the sun-warmed shores of Punaluʻu to embarking on an adventurous cliffside descent into the striking, untouched wilderness of Pololū Valley, each of these unique spaces offers a powerful alternative to traditional white-sand resort coastlines.
Remember that these delicate ecosystems require our protection. Treat these natural monuments with the deep respect they deserve by practicing malama (to care for and protect)—always keeping a safe distance from protected marine wildlife, wearing reef-safe sunscreen to preserve the delicate coral systems, and leaving every single grain of volcanic sand exactly where you found it.
Now it’s time to pack your water shoes, bring your sense of adventure, and get ready to experience the surreal magic of the Big Island's dark coastlines for an unforgettable getaway!
