A flight to Cusco, a night beside Lake Titicaca and a walk over a high pass are different parts of a Peru trip. Alongside place names, record your actual overnight addresses and daily plans. That makes it clear what you want to book and which questions about altitude you want to put to a healthcare professional.

Make an overview for each night
Start with the date and address where you will sleep. Then record how you get there: by plane, road or on foot. Add the accommodation’s elevation when you can establish it through a reliable geographic source or the property. A city elevation provides orientation; do not treat it as a measurement for every nearby address.
Put day trips beside those overnight stops. A pass along the way, a viewpoint and a walk can have different elevations from your accommodation. For an outing, also record its start and end points, transport and the part you want to walk. You can then discuss a specific day rather than just a destination name.
Coast, Andes and different travel plans
Lima on the coast, Arequipa, Cusco and towns beside Titicaca give a journey different geographical parts. Their order on a map does not describe your days. A flight between two cities, for example, might be followed by a night elsewhere and a separate outing. Write down those addresses and journeys, even when a provider sells them as one package.
Compare two itineraries using the same details: overnight address, transport, daily activity and what comes next. Get missing information filled in first. Two lists of places with the same trip length can produce very different days; choose on the basis of the arrangements you actually want to discuss and book.
Take the route to a travel-health consultation
A travel-health consultation uses your itinerary and personal health information. Bring your route, activities and questions. CDC describes the itinerary, activities and medical background as parts of that consultation.
Prepare a short file for the conversation: travel dates, overnight addresses, available elevation information, flights, walks and remote parts of the route. Record how fixed your bookings are and which days you can change. Discuss your medical information and previous experiences directly with the healthcare professional.
Write your questions beforehand. Which parts of this route should you discuss for your own circumstances? What preparation is relevant? What do you want to know about possible medication or travelling with children? Ask for an explanation related to your trip and keep the answers alongside your bookings.
Record what can be changed too
For accommodation, a transfer or an outing, ask what changes if you miss a day or alter your route. Record the contact person, cancellation terms and practical options for changing transport or a room. These are booking questions; discuss medical decisions with your healthcare professional.
For a family or group, make individual overviews where plans differ. You may not all want to do the same walk. Discuss with the provider whether accommodation, a town visit or another day’s activity can be arranged separately and how you will meet up afterwards.
Which information comes from which source?
Start with your accommodation and excursion provider for addresses and daily plans. Use geographic information for elevations and check which place each figure describes. Take questions about acclimatisation, prevention, symptoms or medication to a healthcare professional. CDC’s information on the pre-travel consultation can provide background for that conversation; this article gives no ascent schedule, diagnosis or treatment plan.
Keep the overview and confirmations available offline. When booking and travelling, you will then have the same details to hand: where you sleep, what you arranged and who you can contact about a change.
Questions for the consultation
Which itinerary details should I bring?
Bring the daily itinerary, overnight addresses, available elevation information, transport and activities. Also identify which parts can still be changed.
Should I bring medication?
Discuss prevention and any medication with a clinician who knows your itinerary and health. Do not take dosage or treatment instructions from a travel blog.
