My partner and I took a day to hike around Cajas National Park just outside of Cuenca, Ecuador. It was phenomenal! We hired a guide from Expediciones Apullacta and he was super knowledgeable about the history and geography of the place. It's such a beautiful landscape - kind of eerie and isolated, but definitely worth checking out. I would highly recommend boots and a rain jacket, though, since it can get quite muddy.
