AccessThe shore entry is rocky and the water near the stream can be murky. Visibility often improves toward the sides and outer bay.
ParkingThere are no visitor facilities at the bay. Use legal parking only and follow signs on the access road.
ReservationsNo general snorkel reservation is listed. The bay sits inside the Honolua-Mokulēʻia Marine Life Conservation District.
ClosuresDLNR says winter surf can make both bays dangerous and no lifeguards are stationed there. Wait for calm seas.
Marine lifeFishing and taking marine life are prohibited in the conservation district. Leave coral, rocks, and animals where they are.
