Matanchén Bay: San Blas's Long-Wave Beach Escape

Matanchén Bay is a 7-kilometer (4.3-mile) crescent of golden sand just south of San Blas, and it holds a Guinness World Record for the longest ridable wave ever documented — 5,700 feet at Las Islitas. Swimming is calm here in most spots, the seafood comes straight off the boats, and the whole bay feels a world away from the resort strips further south. That combination makes it the default beach day for anyone staying in San Blas.

Where Matanchén Bay Sits and How to Reach It

The bay begins about 5 to 7 kilometers south of San Blas along Highway 54, the coastal road toward Santa Cruz de Miramar and Aticama. It runs southeast in a gentle arc, passing the villages of Matanchén, Las Islitas, Los Cocos, and Aticama before ending near Miramar. That low, protected curve is why the water stays placid — the bay faces north, so the open Pacific swell gets filtered before it reaches shore.

Driving from San Blas, Tepic, and Puerto Vallarta

From San Blas town, the drive takes 10 to 20 minutes depending on which end of the bay you want. From Tepic, plan on roughly 45 minutes via Highway 54; from Puerto Vallarta, it is about 2 hours 10 minutes on the 76D toll road, and from Guadalajara around 3 hours. Tepic's international airport is a 50-minute drive. Rental cars are worth it only if you plan to explore beyond the bay — Mexcaltitán and Santiago Ixcuintla are the usual add-ons.

Taxis, Combis, and Parking

Taxis from San Blas charge fixed fares, typically 50 to 200 pesos depending on distance; agree on the price before you get in. Combis run from the center toward the bay for about 5 to 6 pesos, though service thins out in the afternoon. There is no bus-style public transport linking the beaches with the town center. A large parking area near the Matanchén village end was built for tour buses, and it is the easiest place to leave a car if you are heading to the palapa restaurants.

What to Do on the Bay

The water temperature runs about 28°C (82°F) in summer and 22°C (72°F) in winter — warm enough for long swims without a wetsuit. The sand is fine, pale, and golden, and the beach is roughly 30 meters wide in places, one of the broadest in Mexico. Long walks, volleyball, and simple sunbathing are the main draws, but the bay rewards a little planning.

Surfing at Las Islitas

Las Islitas is the bay's famous right-hand point break, peeling over a river-mouth sandbar for what can be well over a kilometer on a long-period south swell. The record wave was measured at 5,700 feet. Rides are slow and forgiving, which is why intermediate surfers flock here — leg fatigue, not the wave, usually ends the ride. The break is lightly crowded by Mexican standards. Best season is the south swell window from April through October; the rest of the year is inconsistent.

La Tovara and the Mangrove Estuary

La Tovara is a freshwater spring and mangrove reserve about 2 kilometers southeast of San Blas, and its channels connect directly to Matanchén Bay. Panga boats leave from the Matanchén embarcadero; arrive before 9 AM and you will find lancheros waiting for passengers. The ride passes crocodiles (six is a common count on a good morning), turtles, iguanas, and a wide range of birds, ending at a spring pool fenced off to keep the crocodiles out. Book directly at the dock — no agency needed.

Birding and Wildlife

The Sierra Madre foothills ring the bay, and the surrounding banana, mango, and jackfruit groves draw birds year-round. Las Brisas Birding and Sanctuary, at the far north end near Las Islitas, is the local base for guided birding. Sea turtles surface in the bay, and frigate birds circle the anchorage at dusk. The trade-off is insects: jejenes (no-see-ums) are fierce at dawn and dusk, so bring repellent with DEET and long sleeves for evening walks.

Practical Details, Safety, and When to Go

There is no entrance fee and no reservation system for Matanchén Bay — it is a public beach corridor, open every day. Restaurants along the sand operate from roughly mid-morning until sunset. Fees for boat tours and parking are set locally and subject to change, so confirm prices at the dock or with your hotel before committing.

Best Season and Weather

The dry season from November through April brings sunny days, cooler evenings, and the heaviest tourist traffic around holidays. The wet season from June through October is greener and quieter, with afternoon showers and the best surf. Daytime highs sit in the high 20s to low 30s Celsius year-round. If you want the bay to yourself, aim for a weekday in May or early June.

Safety and Etiquette

Swimming is safe in the protected middle of the bay, but the surf zone at Las Islitas is for surfers. Sharks have been reported in open water outside the bay, so stay inside the curve. Petty theft from boats and cars has been reported historically — lock valuables and avoid leaving anything visible in a parked vehicle. The mangrove reserve forbids removing any living or dead organism and bans fishing inside the protected channels; follow the marked interpretive trails.

Where to Eat

Palapa restaurants line the beach, serving oysters pulled from the bay that morning, shrimp, and whole grilled fish. Matanchén village is also known for banana bread and coconut sweets sold from family storefronts — a small, cheap treat that most day-trippers miss. Expect casual, barefoot-in-the-sand dining rather than white tablecloths.

Frequently Asked Questions

Is Matanchén Bay good for swimming with children?

Yes, in the central and southern stretches of the bay. The protected curve keeps waves small, and the water is warm year-round (28°C in summer, 22°C in winter). Avoid the Las Islitas surf zone, where the long right-hand wave breaks.

Do I need to book the La Tovara boat tour in advance?

No. Pangas leave from the Matanchén embarcadero and you can hire a lanchero directly at the dock. Arrive before 9 AM for the best wildlife sightings and to avoid waiting; tours last a couple of hours and include a stop at the freshwater spring.

How long should I spend at Matanchén Bay?

A half day covers swimming and lunch at a palapa restaurant. Add two to three hours if you are doing the La Tovara mangrove tour, and a full day if you are surfing Las Islitas. Most visitors based in San Blas treat it as a day trip rather than an overnight stay.

What is the best time of year to visit?

November through April for dry, sunny weather and calm water. April through October brings the south swells that make Las Islitas famous, plus fewer crowds and greener scenery, at the cost of afternoon rain.
