Machu Picchu sits at 7,970 feet in the Andes, a 15th-century Inca citadel built without mortar and largely hidden from the Spanish. Most people fly into Cusco, then take a train or do the multi-day Inca Trail hike to reach the gate. The dry months — roughly May through October — give you clearer skies and the famous sunrise over the ruins, though July and August are the busiest. Shoulder months like April, September, and early October often hit the sweet spot of decent weather and fewer crowds.
At around $3,800 for a US traveler including flights, lodging, guides, and the entrance fee, it is the kind of trip people save for over a year. That long runway is also why how you pay for it matters almost as much as when you book it.
The honest catch: the 0% intro period is a deadline, not free money. If a balance is still on the card after 18 months from account opening, interest starts adding up at the card's regular APR, and what looked like $211.11 a month can balloon fast. The plan only works if the full $3,800 is paid off before that window closes.
