Reta: The Argentine Resort with a Unique Underground Tunnel

On the Atlantic coast of Argentina, there are still destinations where silence, nature, and open landscapes are the protagonists. One such place is Reta, a small locality in the district of Tres Arroyos, which has become a refuge for those seeking wide beaches, absolute tranquility, and zero crowds. Located about 580 kilometers from Buenos Aires, this village of just 395 inhabitants surprises with its wild profile: sand streets, low houses, imposing dunes, and over 30 kilometers of coastline on the Argentine Sea.

According to the Argentine News Agency, Reta has a unique detail in the country: a 150-meter subterranean tunnel that crosses the dunes below and allows for a walk to the beach with a direct view of the sea upon exiting. The tunnel was inaugurated in 1998 and was originally conceived as a civil engineering solution: a storm drain to prevent flooding in the urban area. Over time, it has become one of the most curious tourist icons of the Atlantic coast. The experience of crossing it is brief but unforgettable.

Right at the tunnel's exit is another of the resort's main attractions: the sunken ship. During low tide, the remains of this old vessel can be clearly seen, accessible via the ramp on 40th Street. The image of the tunnel, the open sea, and the shipwreck form one of Reta's most photographed postcards, reinforcing the feeling of being in a different place, far from traditional tourism.

Reta is characterized by a virtually untouched natural environment. Even in high season, the beaches remain wide and uncrowded, something increasingly difficult to find in the province. This area functions as a refuge for birds and wildlife, making Reta an ideal point for birdwatching, especially at dawn and dusk. In addition to relaxation, the place invites simple outdoor activities: long walks, sandboarding on the dunes, water sports, and unhurried contemplation of the landscape.

With only a few stable inhabitants, Reta preserves the spirit of an authentic coastal town. There are no private beaches or large constructions; the landscape is dominated by dunes, coastal vegetation, and an open horizon. The area is also home to a lagoon, an ecosystem where fresh and saltwater coexist, which constitutes the first protected area in the Tres Arroyos district. The proposal is complemented by small cultural spaces, such as the unique-in-the-province Museum of Mate, and the community library "A World of Books," which reinforces the resort's quiet and community-oriented profile.

To get to Reta, the most common route from Buenos Aires is to take National Route 3 to Tres Arroyos and then continue on Provincial Road 108-08. Another option is to access it from Provincial Route 72, taking the detour signposted as "Access to Reta."
