Molokini Crater | Maui

Molokini Crater is a marine sanctuary and marine caldera located off the coast of Maui, Hawaii. It's one of Hawaii's most famous snorkeling and diving destinations, known for its clear waters, vibrant marine life, and dramatic underwater topography. The crater is a partially submerged volcanic caldera that offers visitors a chance to explore a diverse range of marine environments, from coral reefs to deep ocean waters. Due to its isolation and protection as a marine reserve, Molokini is home to a wide variety of fish and marine species, some of which are endemic to Hawaii.

Overview of Molokini Crater

• Location: Molokini Crater is situated approximately 3 miles (4.8 km) off the southern coast of Maui, near the town of Ma'alaea. It is a crescent-shaped island, with its open side facing the ocean.
• Formation: Molokini was formed by a volcanic eruption around 230,000 years ago. The eruption created a crescent-shaped, submerged caldera, with the crater's rim remaining visible above the ocean surface. Over time, the interior of the crater has become a rich ecosystem for marine life.
• Size: The island itself is small, measuring about 0.3 square miles (0.8 square kilometers). The crater's rim rises about 161 feet (49 meters) above sea level, while its interior plunges into depths of up to 300 feet (91 meters).

Key Features of Molokini Crater

1. Molokini Crater Marine Reserve

• The area surrounding Molokini is designated as a marine protected area. This designation helps preserve its delicate ecosystem, ensuring that the marine life and coral reefs remain undisturbed by overfishing or commercial activities.
• The clear waters surrounding Molokini are perfect for snorkeling and diving, with visibility often reaching up to 150 feet (46 meters). This makes it one of the clearest places to explore the underwater world in Hawaii.

2. Molokini’s Crescent Shape

• The unique crescent shape of Molokini's rim creates a sheltered environment within the crater, providing calm waters that are ideal for snorkeling and diving.
• The open side of the crescent faces toward the ocean, and the shape of the crater helps protect the interior from strong winds and waves, creating a relatively calm environment for underwater exploration.

3. Vibrant Marine Life

• Molokini is home to over 250 species of marine life, including vibrant tropical fish, corals, sea turtles, rays, and occasional reef sharks. Some of the most notable species include:
  • Moorish idols, parrotfish, and triggerfish.
  • The Hawaiian Green Sea Turtle (Honu) and Hawaiian Monk Seal.
  • Manta rays, stingrays, and various species of sharks, including the blacktip reef shark.
  • The coral reefs surrounding the crater are full of colorful hard and soft corals, which provide shelter and food for the abundant marine species.

4. Molokini Crater’s Deep Waters

• While the shallow areas of the crater are perfect for snorkeling, Molokini’s deeper waters are ideal for scuba diving. Advanced divers can explore deeper parts of the caldera, where dramatic underwater landscapes and larger species of fish and sharks can be found.

Things to Do at Molokini Crater

1. Snorkeling

• Molokini Crater is one of the best places to go snorkeling in Hawaii due to its crystal-clear water, rich marine life, and protected status.
  • Best Spots for Snorkeling: The shallow waters inside the crescent-shaped caldera are teeming with tropical fish, colorful corals, and sea turtles. Molokini’s back wall (the outer side of the crater) is also a popular snorkeling spot for more advanced swimmers due to its dramatic underwater topography.
  • Tours are often available from Ma'alaea Harbor or Maui’s South Shore, where visitors can board boats that take them directly to Molokini for a guided snorkeling experience.

2. Scuba Diving

• Molokini Crater offers incredible opportunities for scuba diving, with both shallow and deep dive sites. The area is known for its pristine coral reefs, steep drop-offs, and variety of marine species.
  • Molokini Wall Dive: This is a popular dive spot along the outer rim of the crater, where divers can descend to deeper waters and explore underwater cliffs and dramatic rock formations.
  • Advanced Diving: Experienced divers can venture deeper into the crater, exploring caves, rock formations, and a wide variety of marine species in their natural habitat.

3. Glass-Bottom Boat Tours

• For those who prefer to stay dry while still enjoying the beauty of Molokini’s underwater world, glass-bottom boat tours are available. These boats allow visitors to view marine life and coral reefs through large glass panels in the boat’s floor, providing a unique view of the ocean below.

4. Whale Watching (Seasonal)

• During the winter months (from December to April), Molokini is a prime spot for whale watching. Humpback whales migrate to Hawaiian waters during this time, and their sightings are common in the area surrounding Molokini.
• Many tour operators offer whale-watching trips in addition to snorkeling or diving trips to Molokini.

How to Get to Molokini Crater

  • Departure Points: Tours usually depart from Ma'alaea Harbor or South Maui's Kihei and Wailea areas.
• Best Time to Visit: The best time to visit Molokini is early in the morning, as the waters tend to be calm, and the visibility is at its best. This is also when the crowds are smaller, allowing for a more serene experience.
