There are some twenty small glacial lakes in the park. All are located to the east of the large walls in a relatively level zone of elevation 2.2 - 2 km. One of the largest is Bird Lake to the northeast of Bird Cliff. A half kilometer to the south is the Lake of Carnations, a small lagoon between the Cliff of Carnations and the eastern slope of Peñalara Peak. In the bed of Peñalara cirque, further to the south, is the circular Peñalara Great Lake, the most extensive in the reserve. It is the most popular with visitors. Approximately .6 km to its southeast is Chica Lagoon, the most distant lake of the cirque: a small and seldom-visited lagoon that commands an impressive view of the Older Sister Mountain, the Peñalara cirque, and Peñalara Peak. All the lakes remain frozen from September until about March.
