Day four
Reach the confirmed Grey shore approach or navigation check-in from your room. Ruta de los Parques gives Guardería Grey → Río Pingo bridge → beach as 5 km and 2.5 hours, without stating one-way or return; ask staff for the permitted endpoint rather than doubling the distance.
For Grey III, choose the round-trip navigation, not the refuge-transfer product. Boat ticket, park admission and road return are separate unless expressly included. If navigation is cancelled, the shore route is an alternative only when staff approve it; wind may prevent that too. Use suitable Pehoé road viewpoints or a quiet property day instead.
Grey III boarding includes a walk across Playa Grey and stated mobility limitations. Discuss them before purchase; a boat seat does not mean minimal walking.
Pingo Zapata is not a substitute: the June regulation lists closure through 10 October 2026; that date passing does not establish reopening.
Day five
Allow for bags, the purchased collection and the Natales room. A final central-lake outlook fits only around that exit; confirm the exact pickup for Pehoé, Grey or Río Serrano, not just the accommodation name. The post-park Natales night allows dinner, luggage collection and rest. Use the Natales guide for a town half-day and the domestic-flight guide for the next connection.
