Is it safe to take the bus at night?

Yes, provided you stick to major, reputable bus lines that use two drivers and GPS tracking. Avoid small, unbranded bus operators.

Should I fly instead?

Flights are faster (1 hour), but by the time you factor in transit to the airport and security wait times, the time savings are marginal. The bus is significantly cheaper and more environmentally friendly.

How to travel overland from Cusco to Arequipa

Travel overland from Cusco to Arequipa by taking a 10-hour overnight bus or a daytime bus. Booking a high-end service like Cruz del Sur or Transzela is essential for safety and comfort on the winding mountain roads.

Book your ticket in advance. Use websites like RedBus or BusBud to compare schedules. Book at least 24 hours in advance to secure a seat on the lower level, which is more stable on curves.
Choose your bus company. Opt for 'cama' (160-degree recline) or 'semi-cama' (140-degree recline) seats with premium companies like Cruz del Sur, Transzela, or Cromotex. Do not use budget companies for this route due to safety records.
Head to the Terrapuerto. Take a registered taxi to the Cusco Terrapuerto (main bus terminal) 45 minutes before departure. You must pay a 'tasa de embarque' (terminal fee) of 2-3 soles at a kiosk inside the station before you can board.
Prepare for the altitude and temperature. The road passes over 4,000 meters. Keep a jacket in your carry-on; bus air conditioning is strong and temperatures drop significantly at night.
