Leg 4 · Cusco, the Sacred Valley & Machu Picchu

Peru

The big one for the Andes — Cusco, the Sacred Valley, Machu Picchu, and some of the highest driving on the route.

! What to watch for

  • Passes over 4,000 m — real altitude-sickness risk for people and engines
  • Narrow cliff roads and sudden weather
  • Strikes and road blockades can close routes for days; heavy Lima traffic

Diesel & DEF

Variable quality; ULSD mainly in cities. DEF is scarce — carry reserve. Power drops noticeably at altitude.

🛂 Borders & permits

Easy entry. Plan fuel around long high-altitude stretches and watch for protest blockades.
