Yixiantian 一線天

Located about 1.8 kilometers northeast of Green Island's Gongguan Port, 'Yixiantian' is an independent reef diving spot in the east-west direction. The east side has a classic '一线天裂缝' (a line of sky crack), with an entrance depth of about 26 meters (north side) and an exit depth of about 15 meters (south side). The reef extends north to a depth of more than 50 meters. This is a high-risk diving spot that requires experience in current control. Those without proper training should not try to cross the crack.
