The park features spectacular mountain landscapes, whose main attractions are the Antuco Volcano, Sierra Velluda and Laguna del Laja (Laja Lake). The latter gives the name to this protected area, but it only borders the park. The park ranges in elevation from 976 m to 3585 m at Sierra Velluda. Although a little snow caps Antuco volcano, much more snow adorns the two major summits of its southern neighbor, even during Chile's summer. Sharp ridges and deep valleys carve this rugged region, which alternates between bare rock and lush vegetation. Another summit in the park, although least prominent, is Cerro Cóndor at 1,668 m.
