About this site

Second Wall lies off Mabul Island in Sabah, on the Malaysian side of Borneo, within the same cluster of dive sites as nearby Sipadan and Kapalai. Mabul sits in the Celebes Sea and is reached by short boat rides from Semporna on the southeastern coast of Sabah. The wall reaches a maximum depth of around 20 metres, and divers have reported damselfish, eagle rays, manta rays, nudibranchs, and snapper along the site.
