A sandy beach with a visible structure in the grass is the take-out for Lago Elizalde. After exiting, make your way through the farmland until encountering a gravel road that leads past the house at the top of the hill up to Ruta X-686.
Ruta X-686 is a lightly trafficked but well-formed gravel road that is fenced on either side. After crossing the Río Paloma, Ruta X-686 makes a sharp left and begins to climb. 4 km after the sharp left turn, cross a bridge to the left and climb to a wooden gate. If you descend the steep slope to the left of the gate, there is camping under some trees.
The wooden gate marks the beginning of a very long driveway to a house located near the lake. The route takes you along this driveway until a river crossing. After crossing the river, walk northeast along its shore towards the Río Paloma. After reaching the end of the fenceline near the Río Paloma, turn east and walk along the fenceline until reaching Lago Desierto. At the river outlet, there is a nice beach to put in to Lago Desierto.
There is no camping along the shores of Lago Desierto. The take-out is a rocky beach at the base of a bluff. Walk up the bluff and cross country through the farmland to Lago Azul. At the east end of the farm, descend down a road to a rocky beach at the Lago Azul shoreline with a metal structure.
There are a couple of potential camping options along the shoreline of Lago Azul. There are also several residences on the north shore. The take-out is a long rocky beach set before a well manicured forest. On the east end of the land near Lago La Paloma is an expensive looking house surrounded by several other buildings.
There is a 4WD track to the west of the smaller red house located south of the big residence. Ascend the steep climb on a well-formed road that is criss-crossed with several smaller tracks labeled in english with wooden signs. Due to the steep slopes on either side of the cut out road, there is no camping here.
Eventually, the route turns off of the road onto an overgrown 4WD track. Camping off the track is still difficult because of prickly vegetation and steep terrain. This track ends 2.5 km from where the Regular Packrafting Route joins the Regular Hiking Route. From here, the route involves some bushwhacking and following a small trail as it winds in and out of existence. Just before joining with the Regular Hiking Route, the route widens into an old 4WD track that passes some destroyed structures.
The routes join up at a large rock cairn and continues to follow a 4WD track until reaching a large wooden sign with a map of the Reserva Nacional Cerro Castillo. Here there is also a campsite and ranger station. There is a 5.000 CLP fee to enter the reserve.
The route from here is a popular track for backpackers with designated campsites. The trail is well-formed and winds through the forest. When the trail becomes less obvious, the way is shown with yellow markers. In this area there is a designated campsite with a latrine.
At treeline, follow the cairns and rocks painted with white and red stripes through the scree up and over the first pass (approximate elevation 1.450 m). After the steep descent, reenter the trees. There is a campsite, Camping El Bosque, soon after reaching treeline (approximately elevation 940 m) with water and a latrine.
The trail begins to wind up through the forest toward Laguna Castillo. The sights from Laguna Castillo, which is at the base of the pass, are stunning. There are two tracks that climb up to the pass. Make sure to take the path that climbs to the south instead of continuing southeast over the obvious saddle.
The track down to Ruta X-720 is well formed, marked, and popular, but occasionally braided. Follow it until reaching the wooden stile with a rangers hut. From there join Ruta X-720, a dirt road which leads to Highway 7 and Villa Cerro Castillo.
