Donut Hole

Depth: 25' - 35'

Overview

A shallow site with a diverse layout, easy to get around even without a guide. The reef has a large round rock with a hole straight through the middle of it, and that is where the name comes from. It sits above the thermocline, so the water is warmer than most of our dives.

What to See

Fish you would find in the intertidal zone: Garibaldi, opaleye, giant kelpfish, calico bass and sheephead. Plus lobsters, urchins, sea stars, nudibranchs and octopi.

Typical Conditions

Open Water / beginner-friendly. Shallow and often warmer above the thermocline.

History

Natural rocky reef in the Point Loma kelp beds.
