(Note from Sinalevi: By means of Article 1 of Executive Decree No. 39259 of October 15, 2015, the following is established: "... Declare as a national park part of the territory established as an Inalienable Zone, created by Decree Law No. LXV of July 1888, annexing said portion of land to Braulio Carrillo National Park; the boundaries of which are described below based on the topographic sheet Barva 3346 II, edition 3-IGNCR, 2005, scale 1:50,000, prepared by the National Geographic Institute of Costa Rica.
Starting from the current boundary of Braulio Carrillo National Park at the point with coordinates 1117735.94-489525.06 (on a tributary of the Porrosatí River). From there, follow downstream along said tributary to the point with coordinates 1116900.75-489349.61 on the current boundary of the Cordillera Volcánica Central Forest Reserve (RFCVC). From there, continue southeast along the boundary of the forest reserve until reaching the intersection point between the boundary of the Cordillera Volcánica Central Forest Reserve and Braulio Carrillo National Park at the point with coordinates 1111363.59-494674.39, continue to the point with coordinate 1.111363.59-495671.22. From this point, head northwest along the current shared boundary between said protected wilderness areas passing through the points with coordinates 1113365.71-493674.76, 1115033.45-493670.16 on the Quebrada Sanguijuela, follow downstream along said stream to the intersection with the Patria River at the point with coordinates 1115262.95-495986.21; follow downstream along the Patria River to its intersection with the Nuevo River at the point with coordinates 1114894.29-498749.52. Continue upstream along the Nuevo River along the current shared boundary between said protected wilderness areas to the point with coordinates 1117574.62-494679.03. Continue on a due north course to the point with coordinates 1118364.01-494679.58. From there, proceed on a due west course to the point with coordinates 1118367.45-489979.30. Continue southwest along the current boundary of Braulio Carrillo National Park until reaching the point with coordinates 1117735.94-489525.06 (on a tributary of the Porrosatí River), which corresponds to the starting point of this description.
In turn, the State Natural Heritage territories described below: From the point with coordinates 1120013 - 486426, which corresponds to the intersection of the current boundary with an old road appearing on the cartographic sheet Barva 3346 II, scale 1:50,000 prepared by the National Geographic Institute, continue northwest and north through the following coordinate points: 1120117 - 486238, 1120165 - 486250, 1120441 - 486161, 1120584 - 486131, 1120936 - 486155, then continue east over points 1120938 - 486189, 1120905 - 486237, 1120882 - 486347, from there continue north and northeast through points 1121073 - 486344, 1121234 - 486487, 1121318 - 486480, 1121653 - 486662, 1121734 - 486754, and then to point 1121685 - 486848, which corresponds to the current boundary of Braulio Carrillo National Park. From there, continue southwest and south along the current boundary of the Park to the coordinate point 1120013 - 486426, the starting point of the current section...")
