Peru hits two extremes in the best way. Lima is one of the great food cities on earth, packed with coastal ceviche counters and world-renowned tasting menus. Inland, Cusco and the Sacred Valley give you ancient stone ruins and high-altitude mountain trails. The dry season runs from May through September, which means crisp blue skies for hiking, but it also brings peak crowds.

A typical two-week run lands around $2,200 once you factor in flights, trail permits, and a few memorable dinners. Instead of draining savings upfront, you can spread the total cost across a year and a half without paying interest.

Keep in mind that an intro period is a hard deadline, not free money. If you still carry a balance after the 18 months end, the card's standard variable rate applies to whatever is left, so treat that monthly $122.22 payment as a fixed bill.
