Site details

A natural sandstone wall at the south end of the Tacoma Narrows near Day Island, just south of Titlow Beach. The sheer main wall runs south of the entry to about 110 ft, with shallower ledges and cutbacks in 40-55 ft to the north and a reported deeper wall starting around 100 ft and running to roughly 140 ft. Swift Narrows currents carve dens that shelter numerous wolf eels and giant Pacific octopus, but the same currents make this an advanced, slack-only dive planned around minor exchanges (max ~2.4 kt predictions); current along the wall runs opposite to the mid-channel flow.
