The park consists principally of cloud forest between 1140 and 3840 meters above sea level.

[1][2] The hills and mountains in Siete Iglesias are very steep, so it sees few human visitors.

The two largest mountains in the park are Siete Igelesias and Pan de Azúcar, or "Sugarloaf."

Farmers who moved near the park in the mid-1900s named the mountain Pan de Azúcar after a kind of bread.

[1] Some scientists report that parks as small as Siete Iglesias do not serve much conservation purpose alone.
