Combi vans in cities
Informal minibuses with a cobrador (conductor) shouting destinations from the door. Cheap and everywhere. Confusing but effective. Locals will help if you ask.
Tip: In Lima, the Metropolitano BRT is the organized alternative. Get a rechargeable card at stations.
Cruz del Sur for long distance
Peru's best bus company. Reclining seats, meals, and movies on overnight routes. Lima to Cusco is 22 hours — or take a 1-hour flight.
Altitude affects everything
Cusco sits at 3,400m. You will feel altitude sickness. Drink coca tea, move slowly, hydrate. Take a day to acclimatize before trekking or sightseeing.
