What We Fish For In San Diego


Our Fishing Destinations

San Diego | H&M Landing

Puerto Vallarta

The Poseidon is based in San Diego, California where it targets some of the best fishing in the world for Bluefin Tuna, Yellowfin Tuna, Dorado "Mahi Mahi" and Yellowtail. We are berthed here from April- Mid October. Here we fish with live sardines and anchovies. Fish from 15-300lbs can be caught in our local waters.




From Oct 15 to the end of November the Poseidon relocates to the most flourish waters ever known "Mag Bay". Where anglers will experience some of the best fishing ever witnessed by humans. Many life forms of marine species migrate outside Mag Bay to target the huge schools of sardines, mackerel and various bait fish. Here you will see whales, dolphins, exotic birds,  pelagic species and Bottom fish. Marlin, tuna from 30-300lbs, Dorado 15-50lbs, yellowtail 15-50lbs, grouper 20-100lbs and many bottom fish are found here for anglers to catch. Topwater, heavy jigs, various trolling lures and almost anything in your tackle box eats it here. We use live sardines and mackerel for bait. These trips are a exclusive fly in fly back opportunity. Flights from LAX & TIJ to Loreto are only 2 hours.




Puerto Vallarta has been our home for our last two boats the Maximus and Constitution for over 15 years. Here we target giant yellowfin tuna to over 400lbs. Average tuna is around 80-120lbs and days we have seen over 20 fish over 200lbs caught in a single day. Due to regulations, and commercial pressure we have found Mag Bay is by far a much rewarding destination for our anglers. Seasons change and as soon as the giant yellowfin tuna show in larger numbers you can be assured we will be running out of Puerto Vallarta.
