About this site
Big Dipper is a vibrant wall dive off Grand Cayman, plunging to dramatic depths. The site features a steep coral-covered wall teeming with reef sharks, eagle rays, and schools of jacks. Sponges and black coral thrive in the currents, while occasional turtles glide by. Visibility often exceeds 100 feet, with mild to moderate conditions ideal for drift diving. The top reef at 40 feet offers shallower exploration before the wall drops into the abyss. A must-dive for its marine life and pristine coral formations.
