Southern Arch
About Southern Arch
Southern Arch is a steep arch formation with near-vertical sides. The depth ranges from around 10 m at the northern end, sloping down to 40 m or more at the southern end. Currents can be strong, and the walls host abundant invertebrate life with nudibranchs commonly seen. Strong flow may also bring in large schools of fish.
