Inkaterra, Peru’s leader in sustainable tourism, celebrates its 40^th anniversary with a brand-new Ruby offer, a nine-day trip that takes guests to four properties across Peru, offering more than 40 activities, such as guided excursions, gourmet meals and spa treatments, along the way. At Inkaterra Reserva Amazonica, stop one with 35 wooden cabanas in the Amazon rainforest, travelers experience one of the world’s most remote and bio-diverse rainforests, the property’s Canopy Walkway and a boat ride to Lake Sandoval. Next stop is Inkaterra Machu Picchu Pueblo Hotel, where travelers discover the world’s largest collection of native orchids, star gaze at Rocotal Observatory, purify at the Andean Sauna and visit Machu Picchu. In the Sacred Valley of the Incas, travelers enjoy a two-night stay at the recently opened Inkaterra Hacienda Urubamba. Guests pick their own produce from the on-site ecological farm, bird watch and visit historic off-site sites. The 11-suite, 16^th-century colonial manor, Inkaterra La Casona, is the final stop, in the heart of Cusco. Travelers can explore Cusco by foot and enjoy the hotel with a gourmet dinner and massage. The Ruby offer starts at $5,200 per person, based on double occupancy. The price includes all 40 excursions and spa treatments.
