Hello! That sounds like an amazing adventure you have planned. Here are some travel tips to help make your visit to Cusco, Machu Picchu, and Lima smooth and enjoyable.

Best Time to Visit:
The best time to visit Cusco and Machu Picchu is from June to August, during the dry season. You can also consider visiting between March and May or September and November, as they are shoulder seasons and can be less crowded. Lima is best visited during their summer months, from December to April.

Route and Accessibility:
To reach Cusco, it's most convenient to fly into Alejandro Velasco Astete International Airport. For Machu Picchu, you'll first reach Cusco, then take a train to Aguas Calientes, the closest town to Machu Picchu and then a bus or a hike to the site. Lima's Jorge Chavez International Airport hosts international and domestic flights.

Accommodation and Booking:
Cusco, Aguas Calientes (for Machu Picchu), and Lima all offer a range of accommodation options from budget hostels to luxury hotels. Online platforms such as Booking.com, Airbnb, and Expedia are good for making reservations in advance.

Clothing and Essentials:
Cusco and Machu Picchu can be cold in the evenings, so packing layers is advised. Rain gear, sturdy hiking boots, sun protection are essential if you plan on hiking. Lima is often warmer and more humid, so pack for a tropical climate.

Health and Safety:
It is important to stay hydrated and protect yourself from the sun, especially when hiking. Try to take it slow when you first arrive to allow your body time to adjust to the altitude. In terms of safety, always keep your belongings secure, especially in tourist areas.

Local Etiquette and Respect:
Peruvians are very polite and respectful. Learn to say basic words in Spanish, like 'please' 'thank you' and 'excuse me'. It's also important to respect the ancient sites; refrain from touching, climbing, or moving anything at Machu Picchu.
