The best beaches near Puerto San Carlos sit on the Pacific side of Baja California Sur, where Magdalena Bay cuts into the coastline. This small fishing port serves as the gateway to one of the largest protected bays in Mexico.
However, Puerto San Carlos is not a typical beach town. Most visitors come here for whale watching between December and April, when gray whales raise their calves in the warm, shallow bay. As a result, the beaches play a supporting role to the wildlife.
Still, the sand here is worth the drive. The beaches on this list pass two tests.
First, the practical test: sand (not rock), public access, somewhere to park, and a way to reach the waterline. Second, the photo test: if you would not stop and take a picture, it is not worth the trip.
In total, two of the best beaches near Puerto San Carlos made the cut. One sits right in town. The other requires a boat.
La Curva: The Town Beach
The Scouting Report
La Curva sits on a crescent-shaped bend in the highway as you enter Puerto San Carlos from the east. The beach curves along the southern edge of Magdalena Bay, facing calm water.
Parking is free along the road above the beach. Also, the drive from Ciudad Constitucion takes about one hour west on the paved highway. From La Paz, the drive takes roughly three hours north and west.
Cell service works in town.
What You Will Find
Essentially, La Curva is the local beach. Families from Puerto San Carlos and Ciudad Constitucion have used this stretch of sand for generations. The shallow water and gentle waves make it safe for children.
Specifically, the sand is soft with some pebbly sections near the waterline. The bay keeps the water calm. You can wade far from shore before the depth changes.
However, La Curva is quieter than most Baja beach towns outside of holidays. During Semana Santa, the beach fills with campers, fishing families, and weekend visitors. The rest of the year, you may have the sand to yourself.
Also, the views across Magdalena Bay are the draw here. On clear days, the barrier islands line the horizon. Pelicans and frigatebirds work the water in front of you.
Before You Go
Furthermore, a few restaurants near the waterfront serve fresh seafood. The port has basic supplies, fuel, and cold drinks.
Additionally, La Curva works best as a stop before or after a whale watching trip. The beach gives you a place to relax while the panga operators prepare for the bay.
La Curva is the beach for the reader who wants a calm bay swim in a working fishing port. One hour from Ciudad Constitucion, and the easiest sand to reach near Magdalena Bay.
Isla Magdalena: The Dune Beach
The Scouting Report
Isla Magdalena is a barrier island that forms the western wall of Magdalena Bay. The beach sits on the Pacific side of the island, backed by massive sand dunes.
Also, there is no road to this beach. You reach it by panga boat from Puerto San Carlos. The ride takes roughly 90 minutes across the bay.
Meanwhile, several tour operators in town arrange day trips and overnight camping excursions.
Specifically, expect to pay between 1,500 and 3,000 pesos per person for a day trip, depending on the operator and the season. Whale watching trips often include a stop on the island.
What You Will Find
Indeed, Isla Magdalena has the most dramatic beach landscape in all of Baja California Sur. The sand dunes rise 30 meters above the shore.
Then the Pacific stretches to the horizon on one side. The bay glimmers on the other.
Essentially, the beach runs for kilometers along the ocean side of the island. The sand is white and fine. Shells collect along the tide line.
Furthermore, there are no buildings, no roads, and no other people.
However, the Pacific side is rough. The surf pounds the exposed shore, and the currents are strong. Swimming is not safe on the ocean-facing beach.
Instead, the bay side of the island offers calm water for wading and swimming. Tour operators typically stop on the sheltered side for lunch and swimming breaks.
Also, the dunes themselves are the main attraction. Hiking to the top takes about 20 minutes. From the summit, you see the Pacific, the bay, mangrove channels, and the desert mainland in every direction.
Before You Go
Bring water, sunscreen, and a hat. There is no shade on the island. The sand reflects heat, and the wind can be strong.
Furthermore, whale watching season (December through April) is the easiest time to reach the island. Tour operators run daily trips. Outside that window, you can still hire a panga, but fewer operators work the bay.
Additionally, some operators offer overnight camping on the island. The glamping camps include tents, meals, and guided hikes. These fill up fast during peak whale season, so book ahead.
Isla Magdalena is the beach for the reader who wants a desert island with Pacific surf and sand dunes. Ninety minutes by boat from Puerto San Carlos, no roads, and no crowds.
Getting to Puerto San Carlos
Puerto San Carlos sits about 60 km west of Ciudad Constitucion on a paved two-lane highway. From La Paz, the drive takes roughly three hours north on Highway 1 to Ciudad Constitucion, then west to the coast.
However, the town is small. Puerto San Carlos has fuel, basic groceries, a few hotels, and several seafood restaurants. It does not have a large supermarket or ATMs from every bank.
Also, the nearest airport is in La Paz. No commercial flights land in Puerto San Carlos.
Best Time to Visit Puerto San Carlos Beaches
The beaches near Puerto San Carlos work year round, but the season changes the experience. Winter (December through March) brings gray whale season. The bay fills with mothers and calves, and tour operators run daily trips.
However, summer (June through September) brings warmer air and fewer visitors. The whales are gone, but the beaches are empty and the water is warm.
In particular, February and March are the peak months for whale watching. The bay has the highest concentration of gray whales during these weeks.
Instead, avoid late summer if you want guaranteed boat access to Isla Magdalena. Fewer operators run trips outside whale season.
Also, check the weather before crossing to the island. Wind and swell on the bay can cancel panga trips with little notice.
The Bottom Line on Puerto San Carlos Beaches
La Curva is the town beach: a calm bay swim on a crescent of sand, walking distance from the port. Isla Magdalena is the dune beach: white sand, Pacific surf, and 30-meter dunes on a barrier island you reach by boat.
Two beaches. Two completely different experiences.
So choose your speed. La Curva gives you an easy afternoon on the bay. Isla Magdalena gives you a desert island.
However, the real reason to come here is the whales. Plan your beach trip around whale season, and you get the sand, the dunes, and the gray whales all in one visit.
