The world's aquarium
What makes the Sea of Cortez special?
The Sea of Cortez is one of the most alive marine environments on Earth. UNESCO World Heritage since 2005, home to 39% of the world's marine mammal species, with whales, dolphins, mobulas, and other wildlife moving through by season.
Cousteau called it “the world's aquarium.” We run small-group trips from La Ventana where the pace is simple: watch the water, wait with patience, and let the ocean decide what the day becomes.

What Makes the Sea of Cortez Special?
The Sea of Cortez — also called the Gulf of California — is one of the richest bodies of water on Earth. It holds 39% of the world's marine mammal species, but what matters most is how it feels when the water goes quiet and something wild appears on its own terms. Bajablue Tours operates from La Ventana, a quiet Baja California Sur village 45 minutes south of La Paz, where the Cerralvo Channel brings deep water, changing seasons, and real ocean surprises within reach.
From La Ventana, we run small-group trips into the waters around Cerralvo Island. We are not here to force the ocean into a schedule. We linger, watch, drift, and help people connect with the sea by seeing it as it is.

November – July
When's the best time to visit?
Each window brings different movement through the water. Pick a season below to see what may be passing through.
November – Early May
Winter Whales & Open Water
Cooler months can bring bigger whales, mobula schools, dolphins, and occasional orcas moving through the rich water around Cerralvo Island. Every day depends on weather, recent activity, and patience.

November through July
When Is the Best Time to Visit?
The best window for marine wildlife in the Sea of Cortez usually runs from November through July, but no two weeks feel the same. Cooler months can bring whales, spring and early summer can bring mobula schools, and orcas move through when prey, weather, and recent activity line up. We plan around the season, then spend the day watching the water and letting the animals choose the moment.

Spring & Summer Migration
Spring and early summer can bring larger mobula schools, mantas, dolphins, whales, and orcas moving with the season. We use the extra water time to wait, watch, and let the animals choose the moment.
Always Wild
The Sea of Cortez is alive year-round. Dolphins, sea turtles, sea lions, reef fish, and other resident wildlife can be present any month, while orcas and large whales move through in seasonal windows.

Day tours start at 8:00 AM. Start time is weather-dependent and may change — we confirm your exact time the day before or the morning of.
The 6-hour day tour (Ocean Safari) meets at the Playa Central boat ramp. The multi-day expeditions (Blue Expedition and Master Seafari) meet at La Ventana Hostel.
Sometimes, when conditions and the animals allow it. We do not chase, force, or rush in. The team positions carefully, waits, and only enters the water when the moment is calm and appropriate. Whales are observed from the boat, and if an animal does not want to interact, we leave it alone.
