For anglers who believe they have already seen it all, Islas Marías represents something truly rare: access to one of the last untouched fisheries in the Eastern Pacific.
Located off the Pacific coast of Mexico, the Islas Marías archipelago has remained protected and restricted for centuries. Limited access, strict regulations and a deep respect for conservation have preserved these waters in a way few places on the planet can still claim.
Tag Cabo Sportfishing is among the very few operations allowed to offer exclusive sportfishing expeditions to Islas Marías, designed for anglers seeking world-class fishing, privacy and luxury without compromising sustainability.
One of the last untouched fisheries in Mexico
Unlike heavily trafficked destinations, Islas Marías has remained largely untouched by mass tourism and commercial fishing pressure. For generations access was restricted, allowing marine life to thrive naturally.
- Healthier fish populations
- Larger average fish sizes
- Minimal fishing pressure
- Exceptionally clean and productive waters
Why very few companies are allowed to fish here
Fishing access to Islas Marías is highly regulated. Only a small number of vetted operators are permitted, and trips must comply with strict rules designed to protect the ecosystem — exactly why the fishery remains so productive today.
- We operate legally and responsibly
- We respect all protected marine zones
- We limit the number of anglers per expedition
- We focus on long-term sustainability over short-term harvest

Islas Marías vs other Mexican destinations
While Cabo offers convenience and Mag Bay offers seasonal abundance, Islas Marías stands apart for one key reason: lack of pressure. Fewer boats, stricter rules and untouched waters mean bigger fish, more consistent action and a genuinely exclusive experience.
How to book
Because of limited access and high demand, Islas Marías expeditions must be planned well in advance. Trips are customized based on season, yacht selection and group size — contact us to check availability.
