Peru stops people in their tracks. Machu Picchu gets the headlines, but it’s the Amazon, the Andes, the food scene in Lima, and the sheer scale of it all that make people realise they need far more time than they planned.

Peru’s climate is shaped almost entirely by its geography. Lima and the coast are mild and overcast for much of the year, Cusco and the Andes have warm dry days and cold nights, and the Amazon runs hot and humid year-round. The dry season from May to October is when the highlands are at their best, with clear skies and manageable temperatures around 18–22°C in Cusco.
Best time to visit Peru
May to October is the sweet spot for most of Peru: dry conditions make Machu Picchu, the Inca Trail, and the Sacred Valley far more accessible, and the views are clearest. The wet season from November to April brings heavy rain to the highlands, though the Amazon is actually more navigable by boat during these months.
Monthly temperature & travel conditions
Spanish is the official language, with Quechua and Aymara still widely spoken in highland communities. English is less common outside tourist areas, so a few basic Spanish phrases will go a long way, particularly once you're off the main trail.
The currency is the Peruvian sol (PEN), and cash is essential for markets, taxis, and smaller towns. Cards are accepted in cities and larger restaurants, but don't rely on them outside the main tourist areas.
Most travelers from the EU, US, UK, and Canada can enter Peru visa-free for up to 90 days. Carry a valid passport and proof of onward travel, as both can be requested on arrival.
Peru uses type A and C plugs with a standard voltage of 220V. Depending on where you're traveling from, you may need both a plug adapter and a voltage converter for certain devices.
Peru is generally safe in popular tourist areas like Cusco, Lima, and the Sacred Valley. Petty theft is the main thing to watch for, keep bags close in markets and on public transport, and avoid walking alone at night in unfamiliar areas.
Driving in Peru is possible but not recommended for most travelers, city traffic is chaotic, mountain roads are demanding, and the distances between key sites are significant. Most people use buses or domestic flights to get around, which is often cheaper and less stressful. Fuel sits around $1.10u2013$1.40 per litre if you do rent a car.
