Connected to the mainland by the narrow Istmo de Ameghino, Península Valdés [1] is 56 kilometers northeast of Puerto Madryn [2] via RP 2, but visiting the major wildlife sites involves a circuit of roughly 400 kilometers to Puerto Pirámides and Punta Delgada via RP 2, Caleta Valdés and Punta Norte via RP 47, and RP 3 back to Puerto Pirámides. Beyond Puerto Pirámides, loose gravel and dirt can be hazardous to inexperienced drivers, especially with low-clearance vehicles.
Broad sandy beaches line much of the coast, but unconsolidated sediments make the steep headlands that rise above them dangerous to descend. Sheep estancias occupy most of the interior, whose Salina Grande depression (42 meters below sea level) is one of the world’s lowest points. The climate is dry, with high evaporation due to long hours of sunlight and perpetual winds.
