Swimming with Giants: A Day on La Paz’s Sea of Cortez
6 hours • Ages 5+ for public tours • All ages for private tours
The boat rocks gently as the marina loosens its grip on La Paz. Salt shuffles over the gunwale, and a horizon that was a flat line a minute ago begins to breathe: fins cutting the surface, a sloped back showing grey-blue, and the slow, deliberate mouth of a creature that has no idea it’s the headline of a day. You slip a mask on and feel the small thrill that comes whenever the ocean makes you a guest. Guides hand out biodegradable sunscreen and snorkel gear, but the real briefing is shorter: respect the animal, move slowly, watch and let the water do the telling.
Trail Wisdom
Rotate When In The Water
Guides limit swimmers to two at a time to reduce stress on animals; follow the rotation so everyone gets equal viewing time.
Use Biodegradable Sunscreen
The boat provides biodegradable sunscreen but bring your own if you prefer a specific brand to protect reefs and marine life.
Secure Your Camera
Use a wrist tether or floating strap for cameras—losing gear in the surf is common and avoid chasing wildlife for shots.
Hydrate and Eat Light
Six hours on the water calls for steady hydration and a light breakfast; avoid heavy meals that can cause seasickness.

Conservation Note
Operators here emphasize minimal-impact viewing—biodegradable sunscreen, limited swimmers, and educational briefings to reduce stress on animals and protect reefs.
La Paz has long been a maritime hub on the Baja peninsula, shaped by fishing, pearl diving, and a growing eco-tourism industry centered on its endemic marine life.

Quick Travel Tips
Book in advance for winter months; bring motion-sickness medication if prone; confirm dietary needs ahead of time; expect limited cell signal offshore
Local Flavor
After the tour, head to La Paz’s Malecón for fresh ceviche or fish tacos and a cold local beer; small seafood stands near the waterfront serve fish stew (caldillo) and are popular with locals.
Logistics Snapshot
Closest airport: La Paz International Airport (LAP) / Marina La Paz: 5–10 minutes from downtown / Cell service: intermittent offshore; expect patchy coverage / Permits: no public permit required but liability waiver and safety briefings are mandatory
