This dive site, known as Crystal Beach or Yamahara Beach, is a secluded underwater gem nestled in Kabira, Ishigaki. It derives its name from the natural crystal deposits carried by Mt. Omotodake’s river, contributing to its exceptionally clear waters. Navigation underwater is generally straightforward due to its shallow average depth and healthy coral reefs providing visual landmarks. While a direct historical account isn't detailed, its remote nature suggests a site largely untouched by mass tourism.
Divers and snorkelers at Crystal Beach can expect to encounter vibrant coral reefs teeming with a variety of tropical fish, including the eponymous clownfish. The site is also a known habitat for sea turtles, offering opportunities for encounters with these gentle marine creatures. The diverse ecosystem includes various other marine life typical of healthy Indo-Pacific coral environments.
The best time to visit Crystal Beach for diving or freediving is likely during periods of calm weather, ensuring optimal visibility in its famed crystal-clear waters. Due to limited facilities and a steep access slope, visitors should come well-prepared with all necessary gear and provisions. Its suitability for all levels, combined with the rich marine life, makes it an excellent choice for both beginner divers and experienced underwater enthusiasts seeking a tranquil and beautiful natural environment.
