Warm rinse water sloshed in the jug as my car hugged a sharp turn on California’s Pacific Coast Highway. I looked left at the mighty Pacific Ocean, the cliffs tumbling to the sea dotted by rugged pinnacles, stretching farther up the coast than the jam band solo currently playing out of the car speakers. Deep blue, favorable conditions all week, minimal swell, no-wind forecast—only unpredictable visibility could affect the diving today.

We asked our contributors what their favorite macro dive was and they answered with stories and images from some of the most beautiful and unique dive sites on the planet.
