The dry Santa Eulalia canyon is just inland from Lima and can be made a day-trip from there or better a two-day trip which includes the higher parts. Drive from Lima to Chosica along the Central Highway and turn left to Santa Eulalia which you just pass through. The dusty dirttrack is a bit rough and a sturdy car is preferred.
In the river look for Torrent Duck and White-capped Dipper and in the orchards you can find Peruvian Pygmy-owl. After having crossed the river a couple of times you will see a spectacular bridge, this is about two hours uphill from Santa Eulalia. The area around the bridge is good for Great Inca-finch. The road across the bridge goes to San Pedro de Casta where there are hotels. Bird the scrub in the switchbacks after the bridge for birds like Rusty-bellied Brush-finch, Rusty-crowned Tit-spinetail, Black-necked Woodpecker and Bronze-tailed Comet. You will soon pass an electrical station and beyond that is the turn-off to the right to San Pedro. Continue left here and pass above the station and drive on for another kilometre there are some scrubby valleys which are good for the rare Rufous-breasted Warbling-finch. Black-winged Ground-dove and Andean Condors can be seen here as well.
If continuing straight instead of crossing the bridge the road goes high up in the valley and Giant Hummingbirds are fairly common here. At the highest part a track continues up and eventually takes you to Marcopomacocha. The left road takes you to two small villages San Pedro de Casta and Huachopampa where you can stay in basic lodging. Sierra-Finches are more common up here and also Canyon Canastero and Black-breasted Hillstar.
If you continue beyond a hidro-electric station (Sheque) along the narrow track to the right you shall eventually cross a small stream which has some trees just next to it. If you look up higher here you shall see more trees and the beginning of the Polylepis forest. White-cheeked Cotinga is often active in the morning as the sun hits the lower trees.
In not entering to Santa Eulalia from the main tarmac road, one can continue to San Bartolome. and from here hike up to the forest of Zarate. It is a long hike of 4-8 hours so one has best to spend the night camping here or get a very early start. This is the only place known where Rufous-breasted Warbling-Finch breeds and from this site the song was recorded for the first time by Charles Hesse in June 2006.
