San Blas Historic Fort: Ruins Above the Pacific

The San Blas Historic Fort, known locally as Fuerte de San Basilio or La Contaduría, sits on a hilltop above the harbor and opens daily from 8:00 AM to 5:00 PM. Entrance costs a small fee — typically under 50 pesos — and the phone number for inquiries is +52 322 285 1180. The site holds the roofless ruins of an 18th-century Spanish fortress, a stone church, and a customs house that once controlled trade between Mexico and the Philippines.

What You'll See at the Fort

The Ruins and Their History

The fort was formally established on February 22, 1768, and soon became the most important shipyard on the Pacific Coast. Ships left from here to explore California and Alaska. The complex includes a ruined stone church — the Temple of the Virgin of the Rosary — soldiers' barracks, and the customs house (La Contaduría), which was built in 1760 to defend against pirates. Cannons still point toward the bay, though the fort has been looted over the centuries and lacks informational signage. A local guide can fill in the gaps; without one, you're mostly looking at worn stone walls and imagining the past.

Reviews on Google average 4.6 stars from over 1,100 ratings, but the common complaint is the same: "Nice viewpoint. The buildings were not so impressive. Not much info given." That's fair. The fort is a shell of its former self, and the Mexican government has not invested in restoration. What remains is atmospheric but sparse.

The Viewpoint

The hilltop position delivers the real payoff. From the fort walls you look down on the harbor, the town's red-tiled roofs, and the mangrove estuaries that stretch south toward La Tovara. On clear mornings the Pacific glints beyond the breakwater. Photographers should arrive before 10 AM to catch soft light on the ruins — by noon the stone gets harsh and the heat builds.

Accessibility and Practical Details

Parking is free at the site, and the approach road is paved. The fort is generally accessible for visitors with limited mobility, though some paths are uneven. Bring insect repellent — the surrounding vegetation harbors mosquitoes, especially after rain. There are no food or drink vendors at the fort, so carry water. The site closes promptly at 5 PM; I saw a guard shooing people out at 4:55 during my visit.

Getting There and Making the Most of Your Visit

How to Reach San Blas

Most travelers arrive by road from Tepic, the nearest city with an airport, about 70 kilometers (1.5 hours) away. From Puerto Vallarta it's a 3-hour drive; from Guadalajara, 4.5 hours. Buses run directly from both cities to San Blas's central plaza, where you can catch a taxi to the fort for a few dollars. If you're driving, take Highway 15 to the San Blas exit and follow signs for El Cerrito — the fort is signed as "Fuerte de San Basilio."

Best Time to Visit

The dry season from November to May brings lower humidity and reliable sunshine. Temperatures range from 25°C to 32°C (77°F to 90°F) year-round, but the wet months (June to October) dump heavy afternoon rain and turn the fort's paths muddy. Mosquitoes are fiercest from July to September. Weekdays are quieter than weekends, when Mexican families arrive in caravans. I'd avoid Semana Santa (Easter week) entirely — the town swells with domestic tourists and the fort's small parking lot fills by 10 AM.

Pairing the Fort with Other Sights

The fort visit takes 45 minutes to an hour. Combine it with the La Tovara mangrove boat tour, which departs from a dock 15 minutes south of town and runs about 2 hours. The restored customs house downtown (also called La Contaduría) is worth a 20-minute stop — it's a different building from the fort's customs house, despite the shared name. Birdwatchers should head to the Singayta estuary at dawn; the area hosts over 300 species, including the endemic San Blas jay. For lunch, the beachfront restaurants at Playa El Borrego serve fresh pescado zarandeado (grilled snook) for around 150 pesos.

What to Bring

Sturdy shoes are essential — the fort's paths are loose gravel and worn stone. A hat and sunscreen are non-negotiable; there's almost no shade. Binoculars reward those who scan the mangroves from the hilltop. Cash is useful for the entrance fee and for tips if you hire a guide at the gate (rates are negotiable, roughly 200-300 pesos for a 30-minute tour).
