THE BEACHES OF THE BIG ISLAND

WHAT’S WHITE, BLACK AND GREEN?
Papakōlea
It is a sure bet that visiting Hawaii would include a trip to a beach and none of these tropical islands will ever disappoint. What sets the Big Island apart from the others though are the varied colors of her beaches. On the north and west of the island are the Kona and Kohala coasts. These are the oldest parts of the island and the beaches here are beautiful white sand. Most of the tourist resorts are in this area.   

The beaches of the east coast and around Hilo are comparatively new and black.

In the extreme southern point of the island, which is also the southernmost point of the United States, there is a rare green sand beach called Papakōlea..

WHERE TO GO?

It is sunnier, warmer and drier on the Kona and Kohala coasts where many tourist resorts are clustered. The combination of pleasant weather and white sand beaches may convince you to travel there, especially since it rains a lot on the Hilo side of this massive island and temperatures there are cooler. 
Hapuna Beach

On our recent visit to the Big Island, we split our time between the two coasts. We stayed for a time in Kailua-Kona and then spent a week at the Hilton property in Waikoloa. We then spent another week at a vacation rental in the Hawaiian Paradise Park (HPP) development.

HPP is about 15 miles from Hilo and 7 miles from Pahoa on the Puna coast. There are rainforests on this side of the island and just 30 miles from Volcano National Park making this must-do destination an easier trek than from the Kohala coast. The beaches on the Hilo side are all black sand and there is a more Hawaiian feel in this area as opposed to the glitzy resorts. 

FIND YOUR BEACH

Depending on what you’re looking for on a trip to the Big Island will determine your beach destination. Don’t worry though, you can’t go wrong wherever you alight. First, let’s explain the colors of the sand and to appease this geeky arenophile who delights in collecting sand.

WHITE SAND

Anaehoomalu Bay

The sand on the beaches of the Kohala coast are white, but it may not be the minute quartz crystals that usually comprise a beach, say in New Jersey.

Instead, the sand is mostly shells from marine life and coral fragments pulverized by the incessant Pacific waves. Because this type of sand tends to have rounded edges it doesn’t stack well and is not suited to building sandcastles.

Here are just a few of the white beaches on the Kohala coast:

Hāpuna Beach

Regularly voted as one of the best beaches in Hawaii, Hāpuna is a mile long and tree-lined offering shade with a lifeguard and a pavilion. It can get crowded. Residents have free entry, but supposedly $10 per car for non-residents. Our recent trip there had a booth, but it was empty.

Anaehoomalu Bay or A-Bay

In the Waikoloa beach area. There’s a lifeguard and free parking, an ancient fish pond and most importantly the Lava Lava Beach Club is nearby offering drinks and food.

Waialea beach (69 beach)

Near Hapuna. Named 69 because of the utility pole marked near the parking entrance. In a small residential community. During the winter months the white sand disappears because of the stronger waves but returns in time for summer. Good snorkeling.

Mauna Kea Beach 

Great for sunbathing. During the summer months when the waves are calmer, it is a good place for snorkeling.

Here’s a live cam of Mauna Kea Beach

Spencer Beach Park

Protected from high surf by an offshore coral reef, this beach park is great for families. Camping is allowed with a permit. There are BBQ facilities, a picnic area and a bathing pavilion.  

Kua Bay

Kua Bay

Secluded white sand beach with beautiful crystal-clear water. Very popular with locals and tourists. Such a great place that Kona Brewing Company named an IPA after it. 

 

BLACK SAND

All black sand beaches on Hawaii are tiny fragments of lava that have reached the ocean. Molten lava cools down quickly when it hits the cold water, solidifying and then shattering into large rocks or big sand granules so to speak. Over time this solidified lava is ground down by the waves into smaller and smoother grains of “sand”.

Newer beaches that have not been ground down can be difficult to walk along barefooted because of the sharper edges and because black sand retains heat very well. Sea turtles often choose black sand beaches to lay their eggs because of the heat retention.

Some of the black sand beaches on the Hilo and Puna side.

Punaluʻu

Punalu'u

Popular beach for Honu or turtle watching, both Hawaiian green sea turtles and the rarer Hawksbill often sun themselves on the hot lava sand. Do not disturb Honu. It’s against the law.

Lifeguard, facilities. Snorkeling visibility can be poor. Only go in the water when the surf is calm.

It’s quite striking to see the blue Pacific, the black beach and the verdant green palms all juxtaposed.

Here’s a nice video of Punnalu views.



Kaimū beach

Lava covered much of the town of Kalapana and Kaimu Bay when Kilauea began erupting in the late 80s creating a young black beach 50 feet over the old beach. Not a place for swimming, but instead to marvel at the power of nature. We did see some locals surfing when we visited. The road ends where the lava carved a path to the sea and located there is Uncle Robert’s Awa Bar and market. On Wednesday nights it is a lively party with music and dancing.  Here's a glimpse at the revelry there.

Isaac Hale (Pohoiki)

In 2018 lava covered the Isaac Hale Beach Park and added acres to the shoreline. A road was carved through the ominous lava after it cooled to reach Isaac Hale. Though quite majestic and with a lifeguard on duty when we visited we were not brave enough to swim.

Kehena Beach

Supposedly nude bathing is illegal, but Kehena Black Sand Beach it is “overlooked”. I guess authorities have more on their hands than grabbing up nudists. Kehena is on the same road as Isaac Hale, McKenzie State Park and Kalapana.

…gone…

Ahalanui Beach Park and Hot Springs
Ahalanui Beach park...gone

This once popular destination did not survive the 2018 eruption. Fed by the cooler ocean water and the thermal warming made this place a unique visit. Ahalanui even had a lifeguard.

Black sand beaches in the Hilo area:

Richardson Beach Park

There are several small beaches around Hilo, but none have any great expanse of sand. Mostly rocky and tide pools, but a great place to see turtles. I once put on my goggles and went under only to come face-to-face with a turtle.

Richardson Beach Park is just one of several in the area.

GREEN SAND

Papakōlea beach is a 49,000-year-old collapsed cinder cone near the South point of the island that is also called “Green Sand Beach”. Glassy olivine crystals are what make up most of the sand on this rare natural display. Other materials like ash, lava and shells are less dense and tend to be washed out to sea, though there are still some found in the sand.

Evidently there are only three other beaches in the world 

Green sand (Olivine) 
that can claim they have green sand. One is on a 
Galapagos Island, another in Guam and a third in 
Norway. None of them though has the grandeur of
Papakōlea with the collapsed cinder cone tilting
towards the Pacific.  

Known locally as Hawaiian diamonds olivine is in the same mineral family as the semi-precious stone Peridot though the latter has a slightly different chemical composition that gives Peridot high-clarity transparent crystals. 

Yeah, I know… blah blah blah.

You can get there from here…

It is a commitment to reach the green sand beach, but worth the effort. There are no facilities here, no lifeguard or concessions, the water can be rough, and to help you reconsider a visit, it is a 2.5-mile hike from the parking lot at South Point.
cliff jumping at South Point

After pondering your life choices by watching brave souls leap 40 feet off the cliffs at South Point (which is an activity enjoyed by native Hawaiians and fearless individuals), follow the windswept trail to the beach. You can’t get lost, just keep the Pacific on your right. There are locals who will offer a ride to the beach for $20 pp, and there were some people maneuvering their 4x4 rentals along the rutty track, but evidently this is frowned on by the Department of Hawaiian Homelands (DHHL). We walked to the beach but hitched a ride with a local and a pickup truck to get back.

Janet thinking about jumping

There are some makeshift steps that lead down to the beach once you arrive and after hoofing in the hot sun or even riding in an open pickup the water is a great reward for your efforts. When we went the water wasn’t that rough and we even had a sea turtle cruise across.
