Lau Lau Bay faces the east side of Saipan and holds a mix of reef and drift sites ranging from very shallow training grounds to deeper offshore water. Shore entry at Lau Lau Beach makes it one of the more accessible dive locations on the island, though thick-soled booties are recommended for the coral entry. East Bay, a kilometre offshore, suits advanced divers and features drift conditions and a large anchor at depth. Green sea turtles, Napoleon wrasse, whitetip reef sharks, and giant morays are among the regularly recorded species, alongside a wide range of nudibranchs. Water stays warm throughout the year.

Temperatures remain warm across all months, making a thin wetsuit sufficient year-round. Conditions at the shore sites are generally mild, though visibility and currents can shift without much notice. The offshore East Bay site is subject to moderate currents and should be treated as a boat dive for advanced divers only.
