Cape Maeda (Blue Cave)

Cape Maeda (Blue Cave), Onna

Cape Maeda, home to the world-renowned Blue Cave, stands as Okinawa’s most celebrated dive and snorkel site. This captivating dive site is famous for its unique natural phenomenon where sunlight penetrates an underwater opening, reflecting off the white limestone walls to illuminate the cavern with an ethereal, electric blue glow. Divers will find themselves immersed in a truly magical, luminous, liquid world, where schools of fish drift through the vibrant azure light, creating an unforgettable spectacle.

The Blue Cave Experience

The Blue Cave itself is a semi-submerged sea cavern, shallow and open to the surface, making it accessible and safe for divers of various experience levels. The maximum depth within the cave typically ranges from 4 to 6 meters. This makes it an excellent choice for beginner divers and those undertaking their Open Water certification.

Beyond the Cavern

While the Blue Cave is the primary draw, Cape Maeda offers a multifaceted dive experience that extends beyond the cavern. As divers venture out, they will discover vibrant outer reefs and intricate wall sections that descend into deeper waters. These areas feature a beautiful hard coral reef, with slopes reaching depths of 22 meters and some sections extending beyond 40 meters, providing ample exploration for more experienced divers.

Marine Life Encounters

The waters around Cape Maeda are renowned for their clarity and abundant marine life, often compared to a "natural aquarium." Divers can expect to encounter a rich diversity of species, including the Broadclub Cuttlefish (Sepia latimanus) and the majestic Green Sea Turtle (Chelonia mydas). The reefs teem with colorful tropical fish such as clownfish, butterflyfish, damselfish, parrotfish, and angelfish. Macro enthusiasts will delight in searching for smaller creatures like nudibranchs, cleaner shrimp, and gobies hiding within the coral formations. Other common sightings include lionfish, scorpionfish, moray eels, and garden eels. The site also boasts over 200 types of coral, creating a thriving ecosystem.

Diving Conditions and Logistics

• Difficulty: Cape Maeda is considered an excellent dive site for beginners, ideal for Open Water Diver courses and introductory dives.
• Certification Required: Open Water certification is required for independent diving.
• Depth: The Blue Cave reaches a maximum depth of 6 meters, while the surrounding reef and wall areas can extend to over 40 meters.
• Water Temperature: Okinawa's water temperatures are comfortable year-round, ranging from approximately 20°C in winter to 30°C in summer.
• Current: Currents at Cape Maeda can be variable. We recommend checking local sea conditions before diving, as strong currents and surge can occur and may lead to the closure of shore access.
• Entry: Divers can access the dive site via shore entry, which involves descending a long stairway of over 90 steps from the parking area to the water. Boat entry is also a popular and convenient option, especially when shore access is challenging due to conditions or crowds.
• Hazards: Divers should be aware of variable currents, potential surge, and boat traffic, particularly near entry and exit points. Always pay attention to your depth, especially in the shallower cave areas. The Cape Maeda management office monitors sea conditions, and diving may be prohibited during high waves or unsafe conditions.

Due to its immense popularity, Cape Maeda can become quite busy, especially during peak seasons and on weekends. For a more serene experience, we recommend planning early morning dives to avoid the crowds. Facilities at Cape Maeda include restrooms, showers, coin lockers, and paid parking.
