Tucked along the shores of the Sea of Cortez, La Paz has long been one of Mexico’s hidden treasures among divers. Balandra Beach—with its shallow turquoise waters, iconic “El Hongo” rock formation, and protected marine ecosystem—is the perfect natural entry point. But what many overlook is that just past the shallows lies one of the most biodiverse underwater paradises I’ve ever experienced.
I’ve dived in world-famous spots, yet nothing compares to the clarity and calm around Balandra Bay, combined with the wildlife-rich reefs and offshore pinnacles of Espiritu Santo and El Bajo. This guide shares the best dive spots, seasonal windows, marine life, conditions, and local must-sees—designed for curious divers eager to truly understand why La Paz is nicknamed “the world’s aquarium”

Balandra’s reef and mangrove fringe offer a peaceful dive in shallow turquoise water—ideal for photography, relaxation, or long bottom times. Dive here when you want a serene, low-impact experience surrounded by natural beauty. - Sea Lion Interaction:
Los Islotes is pure joy for divers. The sea lions treat you like an open-air toy—they’re playful, inquisitive, and endlessly fascinating. - Pelagic and Megafauna Diving:
La Reina delivers majestic manta encounters. At El Bajo, currents and depth blend to attract pelagic hunters like hammerheads, tunas, and mobulas—a clean, energetic dive environment. - Wreck Diving:

Diving off Balandra Beach and exploring the surrounding waters of La Paz unveils a world where tranquility and grandeur coexist beautifully. In Balandra itself, the serene turquoise shallows offer gentle reefs and mangroves, a perfect setting for reflective underwater discovery. Venture beyond, and you’ll find yourself swimming beside eager sea lions, drifting along canyon walls with manta rays gliding above, and witnessing the dance of hammerheads on offshore pinnacles. It’s this extraordinary mix of calm and exhilaration—juxtaposed with some of the clearest waters I’ve ever encountered—that makes diving here feel both deeply peaceful and thrillingly alive.
But the magic isn’t just in what you see—it’s in the way the water envelops you, how marine life opens their world to respectful visitors, and how the landscape above continues that sense of harmony. From the golden sands and rock formations at Balandra to the quiet charm of La Paz’s Malecón, the beauty stretches far beyond the reef. For divers seeking more than a checklist experience—those wanting to feel genuinely connected to the ocean and its creatures—this place has a rare gift: it reminds you of why the sea grabs hold of our hearts, and never lets go.
