Laguna Galarza is located in the Paraje Galarza in the northeastern corner of Corrientes province, within the Gran Parque Iberá wetland system. It sits approximately 100 km from Ituzaingó via Ruta Nacional 12, 318 km from the provincial capital of Corrientes, 120 km from Posadas, 125 km from Santo Tomé via RN14, and 80 km from Virasoro via RP37. The access road is Ruta Provincial 41, a gravel (ripio) road, so a vehicle with appropriate clearance is advisable.

The lagoon functions as the entry point to Laguna Luna, the largest body of water in the entire Iberá hydrological system. Reaching Laguna Luna by boat from Laguna Galarza is one of the defining experiences of this portal, involving open-water paddling or motorboat travel across an expansive mirror of water. The scale of the landscape is striking — wide horizons, an outsized sky, and the transition between open lagoon and the surrounding esteros (marshes) and pajonales (reed beds).

Guided boat excursions operate from the portal, and kayaking is available as an activity. Local guides lead navigation through both lagunas and esteros, with wildlife encounters forming a central part of the experience. Carpinchos (capybaras), yacarés (caimans), herons, and aguará guazú (maned wolf) inhabit these routes. Nighttime navigation excursions are also offered.

The portal has an ecotourism lodge with capacity for up to 120 people. Guided interpretation is available in English and Portuguese. Access to the lagoon itself was improved through canal work undertaken during a recent drought period, so the put-in infrastructure is relatively new.

Water levels in the Iberá system are sensitive to regional precipitation patterns. During drought years, water coverage across the province can drop dramatically, which has historically affected navigation at various portals. Paddlers planning a trip should verify current water conditions in advance, as low water can limit or prevent access to the lagoon and connecting waterways.
