Nonoc Shoal

Nonoc Shoal, located near Larena Harbor, is renowned for its captivating wall dive. However, due to the site's proximity to the harbor and ships, the presence of diverse marine species may be limited. Nevertheless, divers can still encounter vibrant reef fish and there is a slight possibility of spotting graceful green sea turtles. Nonoc Shoal is known to present challenges such as strong currents and reduced visibility, thus making it a more demanding dive site in Siquijor. With a maximum depth of 22m and virtually zero visibility, this dive is only recommended for advanced divers.
