Dive-site story
Located off the rugged northern cliffs of Saipan, Spot Light is a cavern dive defined by a natural aperture in the rock ceiling. Around midday during the calmer summer months, direct sunlight filters straight through this overhead opening, casting a dramatic, focused beam into the darkened chamber below. Outside the cavern, the volcanic seabed drops away into clear oceanic water characterized by large boulders and shelf coral formations.

Seasonality
