Discover Tres Marias: Beach and Nature at Laguna Oca

If you’re looking for a hotel in Tres Marias, it helps to first sort out your travel interests. A key reference point is the Laguna Oca Biosphere Reserve: beaches, warm water, wetlands, and photo safaris give your travel plans concrete nature and landscape themes.

Beach and Nature at Laguna Oca

You can enjoy the beach and swim in the warm water at the reserve year-round. The surroundings invite you to experience nature, and photo safaris are also offered. The beach and photo safaris offer different focuses: time by the water on the one hand, and nature and photography on the other. When planning your trip, you can consider whether beach time or a nature-focused activity should take priority for you.

Wetlands Along the Río Paraguay

The reserve is a wetland fed by water from the Río Paraguay. The Laguna Oca y Herraduras del Río Paraguay Biosphere Reserve was designated by UNESCO in 2001. The river is therefore part of the full name and also the stated water source for the wetland.

Getting There by Car or Boat

To get there in a private vehicle, travel south from the city of Formosa along Ruta Nacional 11. Then take an unpaved road in the town of Tres Marías. Allow time for this stretch and check road conditions before setting out.

The Laguna Oca Biosphere Reserve can also be reached from the city of Formosa by a 20-minute boat ride. This time estimate applies to travel by boat, not by car. If you’re considering this option, check in advance whether you can fit the trip into your travel dates. The practical considerations differ: road conditions matter when traveling by car, while the boat trip’s schedule matters when traveling by boat.

Birdlife in the Wider Region

A study area focusing on the avifauna of the Río Paraguay wetlands extended from the outskirts of the city of Formosa to the town of Tres Marías and included the Laguna Oca del río Paraguay Biosphere Reserve. A total of 260 bird species were recorded in this area. This figure applies to the entire study area, not just Tres Marías or a single location within the reserve. For nature enthusiasts, it places the birdlife in a broader regional context.

Culture in Formosa Province

In the broader travel destination of Formosa Province, the Paseo Ferroviario includes a railway museum, an open-air food promenade, and a cultural and sports center. This adds a distinct regional cultural attraction alongside the nature experience at Laguna Oca. You can consider these separately: Laguna Oca is known for its beach and nature, while the Paseo Ferroviario offers culture in Formosa Province. It also helps to distinguish between the city of Formosa as the starting point for the trip and Formosa Province as the broader travel destination.
