Close to 4.5 miles, further up, you will reach La Retuca. You will cross crop fields and dams, where you can swim. You will also pass by the old big house of the Los Perales Marga Marga Ranch (Fundo Los Perales Marga Marga), where since 1870 sweet, liquor type and generous wines have been elaborated, an inherited tradition from The Congregation of the Sacred Hearts of the French Fathers (Congregación Los Sagrados Corazones de los Padres Franceses), to which the ranch belonged. Its main products are the Frontignan Moscatel and Mass Mature Wine (Vino Añejo de Misa) wines, although they produce other varieties and sparkling wine as well. There’s a sales room.

Alter passing La Retuca take the route to your left that, in 9.3 miles, takes you to the footsteps of the hills, at the end of the valley. Then go up on a slope with many curves and a good view, reaching in 11.8 miles the plains of Colliguay, at an altitude of 1722 feet. Colliguay is located over a plateau of the coastal mountain range, surrounded by hills of regular height and the Puangue marsh, that forms many pools in its descend. After the Battle of Maipú, part of the defeated Spanish army found shelter here, giving birth to the town that today has a population of 600. It’s not a seaside resort, but a village offering some services, summer houses, many vacation centers belonging to different entities, campsites, and it has a lot of activity during Summer. The landscape is unique: the vegetation belongs to a farm land with no irrigation and contrasts with the oasis along the marsh. It’s of interest the “litres” (Lithrea caustica), “boldos” (Peumus boldus), thorn-trees (espinos), peumos (Cryptocarya alba), myrtles (arrayanes), quillalles (Quillaja saponaria) and of course the colliguay (Colliguaya odorifera).

From Colliguay you can reach Route 68, by Curacaví, on a dirt road, very hard at some stretches that runs South along the Puangue marsh.
