Planning Your First Trip to Peru

Planning a trip to Peru requires prioritizing altitude acclimatization in Cusco before tackling high-elevation treks. You must book your Machu Picchu train and entry permits at least 3 months in advance to ensure availability.

1. Secure your permits early. If you plan to hike the Inca Trail, you must book 6–8 months in advance through a licensed operator. For standard Machu Picchu entry, buy your tickets online at the official government site exactly 3 months ahead.
2. Plan for altitude. Fly into Lima and spend 1 night there, then fly to Cusco. Stay in the Sacred Valley (lower elevation than Cusco) for 2 nights to acclimate before heading to Machu Picchu or doing high-intensity treks.
3. Select your regional transit. Use internal flights for long distances (e.g., Lima to Cusco, or Lima to Arequipa) to save time. For shorter distances, use luxury bus lines like Cruz del Sur rather than local minivans.

Do I need to worry about altitude sickness?

Yes. Most people feel symptoms above 8,000 feet. Drink plenty of water, avoid alcohol for the first 48 hours, and ask your doctor about acetazolamide (Diamox) before you leave.

Is it safe to drink tap water?

No. Only drink bottled or filtered water. Even for brushing your teeth, use bottled water to avoid digestive issues.
