Bahía López
Continuing west and then south, the road enters the deeper forest of the circuit at around kilometre 33, where the Puente del Arroyo la Angostura crosses the narrow channel connecting Bahía López with Lago Moreno. From the bridge there are views of both lakes simultaneously, with Cerro López rising steeply to the west. Just beyond the bridge, the road reaches Bahía López itself: a quiet pebble-and-sand beach on the southeastern arm of Lago Nahuel Huapi, tucked below the rock walls of Cerro López and Cerro Capilla.
The beach has no fixed services — bring water and food. Kayaks can be rented at the beach, and the calm water of the bay makes it one of the better spots on the circuit for paddling without fighting wind. A trail from the beach also leads upward toward the Mirador Brazo Tristeza, a moderate-effort ascent that opens onto a panoramic view of the lake's western arm. The name — Brazo Tristeza, or Arm of Sadness — has the melancholy of a Patagonian weather forecast. Foxes are occasionally seen near the bridge.
