Just outside historic downtown Santiago is a corridor of several parks, built on reclaimed land from the Mapocho River. The 4+-mile linear park features three major parks and several of Santiago’s most important museums and landmarks. The heart of the run is Parque Forestal, which incorporates the Museo de Arte Contemporaneo, the Museum of Pharmacy, several monuments, and the Baquedano Square, a major urban gathering place dating back to 1875,
One can run for about 4 miles along this riverside greenway, from Parque de los Reyes in the west, through Parque Forestal, Parque Balmaceda. The parks have nice cement sidewalks and some gorgeous rows of Oriental Plane, so it’s a nice respite from the crowded downtown streets (which are pretty much impossible to run on). There’s a short section between Parque Reyes and Forestal where you have to default to the road for a few blocks. All in all, a loop around the three parks is about 11.4 km (7 miles).
