Tokyo is a city full of lights and oddities; while there, you should check out the Harajuku district for its fashion scene, cross Shibuya Crossing, and hang out in the cafés and arcades of Akihabara. Kyoto is Japan's cultural and historical center, and it is home to phrazle many Buddhist temples, royal palaces, Shinto shrines, and beautifully landscaped gardens.

In the winter, the island of Hokkaido in Japan's northernmost region becomes a skier's paradise, and the island's natural hot springs become a daily need for adventure seekers. Or, you may ski the Japanese Mountains on Honshu, the main island, and then stop at Jigokudani Monkey Park, where the monkeys love to soak in hot springs. The Okinawa Islands are the place to go if you're in search of warm sand and gorgeous blue seas.

Many visitors have been intrigued by Machu Picchu's Incan citadels for centuries, as well as the city's enormous agricultural terraces and stunning mountain vistas. Yet, it may take some time to plan the journey's logistics, and many of the most memorable adventures may be had by just packing a bag and setting off on foot. That's why this journey is ideal for intrepid tourists in their forties who have the experience, flexibility, and financial means to plan a vacation of a lifetime.

In addition to the highlight of your trip—the ascent to Machu Picchu—be sure to appreciate Lima and Cusco, both of which are on the UNESCO World Heritage List. You may choose to drive, ride the train, or go on a trek on numerous itineraries. Stay on the Inca Trail for the whole authentic experience, but if you want to escape the crowds, at least the worst of them, consider reserving a spot on a walk that goes around Salkantay Mountain. Trips to the Lares area are one of the optional extras. Very little could possibly go wrong.
