Region
Southern Sierra
Base in Cusco or Ayacucho and travel by day bus; unpaved roads make night travel and tight connections a bad bet.

- South America ↗Above 2,500 m (Bogotá, Quito, Cusco, La Paz) keep the first day light; sleep lower where you can (Sacred Valley before Cusco) and descend if headache comes with vomiting or confusion.
- South America ↗A yellow fever certificate is required on arrival in French Guiana, and asked for on some routes into Bolivia, Paraguay, Suriname and Guyana, or when arriving from Amazon areas — vaccinate at least 10 days before travel and carry the card.
- South America ↗Overnight buses are the norm in Argentina, Chile and Peru, but pick top-tier companies and keep valuables on your body; on-board thefts from overhead racks are the common loss.
- Peru ↗Check entry rules for your passport with Peru's migration authority (Migraciones) or a Peruvian consulate; keep the entry record you receive, as hotels may ask for it.
- Peru ↗Machu Picchu entry is by timed ticket for a named circuit, with daily caps; in high season tickets sell out weeks or months ahead. Buy tickets only from the official Ministry of Culture seller or a licensed agency.
- Peru ↗The classic Inca Trail needs a permit booked through a licensed operator, often months ahead; the trail closes every February for maintenance.
- Peru ↗Altitude sickness is common above 2,500 m: ascend gradually, rest on day one, and ask a doctor before travel if you have heart or lung conditions.
The Southern Sierra is Peru's high spine: the departments of Ayacucho, Apurímac, Cusco and Puno, cut by steep valleys and linked mostly by slow, often unpaved roads. It is not a single destination but a chain of market towns and Inca and colonial sites at 2,700–3,500 m. Sleep in one base per cluster — Cusco for the Inca heartland, Ayacucho for the western sierra — and treat the rest as long day trips or one-way bus hops. The central valleys around Huancayo, Tarma and Jauja are an adjacent extension of the same highland belt, reached from Lima, not from Cusco. Altitude, not distance, sets the pace.
