Scotts Head Pinnacle

Scotts Head Pinnacle is one of the most well-known dive sites on the island. Divers frequently request return visits to this location. The dive begins on Swiss Cheese, a large rock formation that is home to the famous Soldierfish Cave. This swim-through, which is not technically a cave, is usually teeming with soldier fish and grunts that form a curtain in front of you, briefly parting to swallow you into the school as you pass through.

The Pinnacle can be reached by crossing a flat area of coral-encrusted rock formations. A picturesque swim-through bisects the pinnacle at a depth of only 35 feet, bringing you to the "other side" — a steep wall on the inside of the volcanic crater that drops off to more than 120 feet. Black bar soldierfish, grunts, and lobster can be found in the swim-through. If you're brave enough, you can descend the wall to see swaying sea fans and beautiful gorgonians.
