The 2.5-hour walk to Mandor Waterfalls starts out from the town of Aguas Calientes and follows railroad tracks along a river, past homesteads and orchards to the cloud forest. While the falls are not as dramatically high as some, the hike is easy and full of local sights with marvelous orchids and hummingbirds abound the trail. Another plus? The water is cool and refreshing, particularly in the region’s sticky climate. Pack a picnic lunch (and insect repellant) and make an afternoon of it.
