The Rincon Mountains are also included in the Madrean sky island mountain ranges of southeast Arizona, extreme southwest New Mexico, and northern Sonora Mexico.

Rincón is Spanish for corner, denoting the primary shape of the mountain range.

The interior of the corner is Rincon Valley (south and west of Mica Mountain), primarily former ranchland currently being converted to tract housing.

Colossal Cave county park, a limestone cave and popular destination, is located on the east end of the Rincon Valley, north of the community of Vail.

Between these two ranges is Happy Valley, a popular destination for locals for camping, hunting, and off-roading.
