This is often considered the most beautiful day of the trek. After a delicious breakfast, we hike deep into the protected area, a lush ecosystem where, with some luck, we may spot Andean deer and a variety of exotic birds. About 30 minutes into the hike, we will arrive at the circular archaeological group of Runkuraqay. We continue our ascent to the second pass and then descend to explore Sayaqmarca, another impressive archaeological site perched on a cliff. After exploring these ruins, we walk for another 15 minutes to Ch'akiqocha, where a delicious lunch awaits us. Recharged, we continue to Phuyupatamarca ("Town in the Clouds"), a site famous for its ritual baths and views. Finally, we descend for approximately two and a half hours through the cloud forest until we reach the spectacular Inca citadel of Wiñayhuayna ("Forever Young"). We will explore this stunning site and spend our last night camping nearby, full of anticipation for the grand finale.
