Coronado’s Are a Must-Do!
Just off the coast of Baja California lies the rugged and remote archipelago known as the Coronado Islands — a unique dive destination that offers more than your typical day-trip. Although you're only a short boat ride from San Diego, you’ll be immersed in Mexican waters, surrounded by clearer seas, abundant marine life, and a wild-water vibe that feels far from your shore-dives.
You will see:
Playful sea lions: The pups are curious and interactive — expect them to buzz past you, blow bubbles, or pop into your frame unexpectedly.
Diverse reef life: From Garibaldi and moray eels to scorpionfish, two-spot octopus, and other macro critters, the ecosystem is rich.
Signature dive terrain: Sites like “Lobster Shack”, “Keyhole”, and “Middle Grounds” present a mix of shallow vistas, drop-offs, arches, and ledges — plenty of variety for different experience levels.
Surface pass featuring big water: On our return trip, we’ll skim over deep channels and the trench near the islands — a chance to watch dolphins or whales from the deck as the sun begins to dip.
Typical Conditions & Gear Tips
Visibility: On a good day, expect 30-70 ft (9-21 m); average hovers around 50 ft.
Water temps: Surface temps often in the 60-70 °F (15-21 °C) range. Deeper or thermocline zones may drop into the low 50s °F (10-12 °C).
Recommended gear: Since you’ll dive several sites in one day, and conditions can vary, plan for a 7 mm wetsuit (or equivalent), hood, booties, and gloves. Surge can occur, especially in arches or channels.
Bonus tip: Because it’s a full-day charter, a dry-bag with a change of clothes and a light towel will keep you comfortable for the ride back.
