49 Black Sand Beach - Deep Research Report

Deep Research Report

Last updated: April 23, 2026

What it is

49 Black Sand Beach, officially known as Honoka'ope Bay Beach, is a unique black sand beach located within a volcanic bay near the Mauna Lani Resort on the Kohala Coast of the Big Island of Hawaii. It is distinctive for being the only black sand beach on the Kohala Coast. The black sand is composed primarily of fine grains of lava, formed from a 19th-century lava flow from Mauna Loa that reached the ocean. Unlike many black sand beaches that are very fine, the sand at 49 Black Sand Beach can be coarse and contains pebbles, sometimes appearing more dark gray than jet black. The beach is situated in a small cove, buffered by natural lava rock walls on both sides.

Visitor experience

Travelers choose 49 Black Sand Beach for its unique black sand and its generally uncrowded, serene atmosphere, largely due to controlled access. The calm, clear waters in the protected cove make it suitable for swimming and offer good snorkeling, particularly along the rocky edges of the bay and towards the center. Snorkelers can expect to see tropical fish and underwater rock formations. Hawaiian green sea turtles (honu) are frequent visitors and can sometimes be seen basking on the warm black sand.

Beyond the beach itself, visitors can explore tide pools (being mindful of sharp lava rocks) or walk a sea cliff trail that tracks along the rim of the bay, offering views of tide pools and sea coves. The beach has public restrooms and an outdoor shower.

Logistics

Area & Access: 49 Black Sand Beach is located within the Mauna Lani Resort area on the Big Island's Kohala Coast. To access it, visitors must exit the Queen K Highway (Highway 19) into the Mauna Lani Resort. From the roundabout (near Foodland and Mauna Lani shops), take the third exit onto Kaniku Drive, then a left onto Honokaope Place, following it to the end.

Parking & Permits: Access to the parking lot is controlled by a guard shack, and visitors are required to stop and request a beach pass. There is a limited number of public parking stalls (around 20 cars), and these passes are limited daily. Arriving early in the morning is highly recommended, as parking often fills up, and visitors might be turned away if the "Beach Parking Full" sign is displayed. There are no fees for the beach pass itself.

Timing & Duration: The beach is open daily from sunrise to sunset. Given the limited parking, an early morning arrival is best. It can be enjoyed as a quick stop to see the unique black sand, or as a half-day activity for swimming, snorkeling, and relaxing.

Amenities: Public bathrooms are located next to the parking lot, and a shower is available near the trailhead above the beach.

Safety and cautions

  • Hot Sand: The black sand absorbs the sun's heat intensely and can get very hot. It is advisable to wear sandals or water shoes.
  • Sharp Lava Rocks: The sea cliff trail and edges of the beach area contain small lava rock reefs, which can be sharp. Water shoes are recommended for swimming and snorkeling to protect feet.
  • Water Entry: The beach has a steep slope into the water, which can be challenging depending on the surf. The waters can also get deep relatively fast, so supervise children closely.
  • Ocean Conditions: While generally calm due to being in a cove, ocean conditions can vary. Snorkeling is best when the water is clear and calm. There are no lifeguards.
  • Lack of Shade: There is very little natural shade at the beach. Bringing a beach umbrella, plenty of water, and sunblock is highly recommended.
  • Marine Life: If Hawaiian green sea turtles (honu) are present, observe them from a respectful distance (usually 10-20 feet) and do not disturb them.

Editorial take

49 Black Sand Beach is a highly recommended stop for travelers seeking a distinctive beach experience away from larger crowds. Its unique black (or dark grey) sand, calm waters, and good snorkeling opportunities make it a strong candidate for a half-day activity. It particularly suits those interested in natural geological formations and marine life.

Travelers who should prioritize it include snorkelers, families looking for a less crowded beach, and those wanting to see a unique black sand beach on the Kohala Coast.

Travelers who might skip it are those looking for extensive white sandy beaches with abundant shade, or those unwilling to arrive early to secure a parking pass. The limited parking can be a deterrent for spontaneous visits.

It should not be confused with other black sand beaches on the Big Island, such as Punalu'u Black Sand Beach (which is a true black sand beach made of volcanic glass) or the black sand beaches on Maui (like Honokalani/Pa'iloa at Waiʻānapanapa State Park, which require advance reservations and fees). This specific beach is known as "49 Black Sand Beach" due to the 49 residences behind it, and is within the Mauna Lani Resort area, accessible via a pass.
