About this site
Crack (クラック) is a boat site at Tanabe on the Kii Peninsula of Wakayama, with depths of 10 to 25 m. A large rock carries a long arch, and in winter the site is a rich ground for nudibranchs, while ornate ghost pipefish are often spotted where the water moves well. The site is suitable from beginner level.
