Coronado Islands Fishing: Mexico's Water, 14 Miles From San Diego

Four rocks, one border, and a very different fishing day

The Coronados sit in a line running roughly northwest to southeast off the Tijuana coast. The biggest and southernmost, South Coronado, is about 13 kilometers — eight miles — off the Mexican mainland and roughly 12 kilometers, or seven miles, south of the maritime border with the United States. North Coronado anchors the other end. Between them sit Middle Coronado and a steep sugarloaf of rock the charts call Pilón de Azúcar and the fleet calls Middle Rock.

None of them is big. South Coronado covers 183 hectares, about 450 acres; North Coronado 48 hectares; Middle Coronado 14; Pilón de Azúcar 7. South Island carries the high ground, with Middle Peak at roughly 180 meters — 590 feet — and South Peak at about 160 meters. The only people living on any of them are Mexican Navy personnel and a lighthouse keeper on South Island.

For an angler the geography is the point. Four pieces of rock dropped into deep, current-swept water create kelp on the lee sides, boiler rock on the weather sides, and hard structure running out into 40 fathoms — everything the Southern California fishery wants, packed into a few square miles that Californian boats can only reach by leaving the country.

Which San Diego trips actually go there

There is no half-day Coronado trip. The islands are a full-day product at every San Diego landing that runs them, and the pricing gap between a Mexican-water trip and a local one is the clearest number in the fleet. The table below takes published 2026 schedules from four San Diego landings on the same set of mornings, so the comparison is like for like.

One row is worth reading twice. H&M Landing prices the Grande as a whole-boat charter, and the islands version is about a thousand dollars cheaper than the offshore version — "Full Day Islands" at $6,950 to $8,500 against "Full Day Offshore" at $8,225 to $9,375, both to a maximum of 40 passengers. That is fuel. The islands are 14 miles out; the Grande's offshore trips "venture up to 50 miles offshore." The boat that costs less to run is the one that crosses a border.

• Seaforth sells the islands as its own product and says of the Full Day Coronado Island trip that "Mexican Permits are usually included in the ticket price" — which is not the same as the passport and FMM, and those are not included.
• The same boat runs both destinations. Point Loma's Mission Belle was listed as "MEXICO — Offshore" on October 1 and "CORONADO ISLANDS/MEXICO" on October 2 and 3, at the same $258.75, from the same 5:30 a.m. departure.
• Grande Sportfishing's own page describes the choice plainly: "Departing daily at 5:30AM, fish the legendary Coronado Islands or offshore for tuna."

The paperwork is the gate, and the bracelet is the part people miss

Three separate Mexican requirements stack on a Coronado Islands trip, and they come from three different agencies. The sportfishing permit comes from Mexico's fisheries authority and is required of every person aboard a boat carrying fishing gear in Mexican water. The FMM visitor permit comes from immigration and is triggered by proximity to Mexican land — H&M Landing's own FAQ states that "if a trip is operating within 12 miles of the Mexican coast of any of their islands, a Mexican Tourist Visa (FMM) is required," and names "Full Day Coronado Islands" as the example.

The third is the one that catches people out. The islands sit inside a Mexican federal protected area, and entering it for recreation carries its own fee, collected through a wristband the fleet calls a biosphere bracelet. Fisherman's Landing lists it as a standing requirement — "Mexico now requires anglers fishing specific Biospheres such as the Coronado Islands to purchase biosphere bracelets" — and sells them in its tackle shop. H&M Landing's charter terms spell out that its rate "does not include: Mexican Fishing Permits, Bracelets, Mexican Tourist Visas (FMM – Passports required) California fishing licenses, or meals."

A passport is not optional here and a driver's license will not do. Point Loma Sportfishing's schedule says "Passport or passport card required" on the Coronado departures. Fisherman's Landing is blunter still: "Everyone needs a passport no exceptions," adding that "Passport cards are valid." Our Mexican fishing license guide covers the permit fees, the 12-mile rule and Mexico's bag limits in full; this page assumes you have read it or will.

• Some tickets bundle some of it. H&M Landing says only that "some trips include the Mexican Sportfishing License and Mexican Visa in the price of the ticket; some do not" — so ask when you book, not at the gangway.
• A California license still matters if the boat may fish home water on the way in or out. On a trip that stays entirely in Mexico, ask the landing; on one that could go either way, carry it.
• Bracelets are sold at the tackle shops at Fisherman's Landing and Point Loma Sportfishing, so a last-minute seat is workable — provided the passport is already in your bag.

It is a biosphere reserve, and you cannot set foot on it

The bracelet is not a landing tax invented by the boats. On December 7, 2016, Mexico published a decree in the Diario Oficial declaring the region known as Islas del Pacífico de la Península de Baja California a biosphere reserve. It covers 1,161,222.97 hectares — 70,139.62 of them land and 1,091,083.35 marine — across 21 islands and 97 federal islets. The Archipiélago Coronado is one of eight polygons inside it, about 15 kilometers off Tijuana, and its polygon alone runs to 18,529.57 hectares.

The practical consequence is simple: you fish the water, you do not touch the rock. Landing on the islands is prohibited without specific permission from the Mexican government, and in practice access is restricted to government personnel and permitted scientists. Nobody on a party boat is going ashore, and no legitimate operator will offer to put you there.

It is worth understanding why the reserve exists, because it explains the fishing. Mexico's Pacific islands are seabird and pinniped strongholds, and the Coronados carry a sea lion haul-out that anybody who has fished the lee of South Island has heard before they have seen it. Protection of the land has left the surrounding water with structure, bait and far less shoreside pressure than the equivalent rock on the California side.

What actually comes over the rail

This is where the Coronados earn the extra money, and it is also where the brochure language stops being useful. The table below is not a promise; it is five dated Coronado Islands full-day trips that the Grande, out of H&M Landing, published on its own reports page, with the angler count for each.

Across those five trips, 141 anglers landed 187 yellowtail — about 1.3 fish a head — but the spread between trips is the honest story. The best day was 53 yellowtail for 23 anglers. The slowest was 20 for 29. Same boat, same island, three weeks apart.

The mixed bag is the other half of it. Look past the yellowtail column and you find barracuda, calico bass, whitefish, rockfish, red rockfish, sheephead, bonito and lingcod, sometimes eight species on a single ticket. A more recent example: H&M Landing's Malihini posted a full-day Coronado Islands count on September 27, 2026 of 91 yellowtail, 52 rockfish, 47 calico bass, 43 whitefish, 19 sculpin, 16 sheephead, 15 bonito and 1 skipjack. That variety is exactly why a full day at the islands appeals to anglers who find an offshore tuna run either feast or famine.

The marks: North Island, the Middle Grounds, South Island and the Rockpile

Crews work the chain rather than one spot, and the shorthand on the rail is worth knowing before you hear it. Writing for BD Outdoors on September 26, 2025, Nathan Winicki described the late-season pattern as running "from North Island to the Middle grounds, working all the way down to the tuna pens in the lee of South Island." Those three names cover most of a day.

North Island is the first stop for a boat coming down from Point Loma and the most exposed of the group. The Middle Grounds is the broken water between the islands — hard bottom, current lines and the kind of structure that holds bait when the surface looks empty. The lee of South Island is the calm-water option and the fallback when it blows, and it is where the tuna pens sit: commercial bluefin grow-out cages that attract bait and fish and are fished around rather than through.

One more name comes up in every serious conversation about the islands. "Eight miles below the Lighthouse on South Island lies a high spot dubbed 'The Rockpile'," Winicki writes — a pinnacle well south of the chain itself, fished when the boats have time and the weather to get there. If your captain mentions it, the day is going well.

• Surface iron, yo-yo jigs, dropper loops, flylined bait, slow-trolling and casting metals all have their moment here; late-season yellowtail on pressured days respond to downsized gear, 20 to 25 pound leader and smaller hooks.
• A full day gives the crew room to try three or four of those marks. That is the argument for the islands over a 3/4 day at home, where the boat has one area and one plan.

When to go, and why the same boat alternates

The Coronados are not a summer-only fishery, but they do have a window that the people who fish them defend. Winicki's assessment is that "this area finds its best fishing from mid-September through late October, with those trying their luck in early November," and he frames it as the last good score "before the cold water shuts everything down." That is the late-season bite, and it comes with fewer boats than July.

Earlier in the year the pattern is different but real — the Grande's own reports show productive island trips through the first weeks of July. What changes as summer peaks is competition from offshore: when tuna and dorado are inside a day's run, the same boats that fish the islands go looking for them instead, which is exactly what the Point Loma schedule showed for October 1 to 3, 2026, with the Mission Belle listed offshore one morning and at the Coronado Islands the next two.

The other calendar to check is California's, not Mexico's. CDFW's 2026 groundfish rules for the Southern Management Area — Point Conception to the border — run open at all depths from April 1 to June 30, inshore of 50 fathoms from July 1 to September 30, and from October 1 to December 31 nearshore rockfish, cabezon and greenling are "Closed — unlawful to possess in all waters," with shelf and slope rockfish and lingcod restricted to outside 50 fathoms. Ask your boat what is retainable on your date; the rockfish column in a July island count is not a promise for a November one.

Getting the fish home: the declaration almost nobody files

Fish caught at the Coronados are imported into California when the boat ties up, and California has a form for that. Section 712.5 of Title 14 makes it "unlawful to import any dead birds, mammals, fish, reptiles, or amphibians into this state" unless a completed CDFW Declaration of Importation of Dead Fish or Wildlife, form DFW 901, is submitted "by mail or online prior to or at the time (within 24 hours) of entry." CDFW's own enforcement page says a copy of the declaration, or the online confirmation number, "shall be retained with the dead fish or wildlife." The one exemption is for shipments handled by a common carrier under a bill of lading.

Underneath it sits Fish and Game Code section 2353, which permits fish taken outside California to be brought in only when they were lawfully taken and California does not prohibit possessing them. That second clause has teeth. Four rockfish species — bronzespotted, cowcod, quillback and yelloweye — carry a zero-fish limit in California for 2026, and CDFW's published guidance is that species prohibited here cannot be brought back even when they were legally caught in Mexico. The department has also pointed out that filleting is not permitted in Mexico, so fish taken there cannot come back into California filleted.

This is a paperwork problem, not a reason to skip the trip. Ask the landing how they handle the declaration for their passengers, do it on your phone if they do not, and keep the confirmation number with the sack. Our bag and size limits guide has the California numbers species by species for the moment you get home.

A Coronado Islands seat at a last-minute price

Coronado trips are where last-minute seats do the most good, for a reason peculiar to this destination: passenger loads are capped low and the paperwork thins the pool of people who can jump on a spot the night before. The Mission Belle's October 2 trip was carrying 13 of 30 the week before it ran. Seats like that are what the discount is for.

Mixed Bag Sportsman lists open spots as California captains submit them. Every deal is reviewed before it goes live, you book directly with the boat, and the price is whatever the captain set to fill the rail. If you want in on a Coronado Islands seat at short notice, the only real preparation is the one nobody can do for you: keep a current passport in your fishing bag.
