The 18th-century Real Fábrica do Gelo supplied the royal court in Lisbon with ice, using natural condensation and thermal insulation techniques.
The summit serves as a major migration corridor for various raptor species, making it a premier location for ornithological observation.
The mountain range serves as a climatic barrier, significantly influencing the rainfall patterns of the surrounding lowlands.
It contains a series of limestone caves and karstic formations that are monitored for geological stability.
The area remains one of the few places in the region where traces of ancient holm oak forests persist.
Serra de Montejunto is a limestone massif forming the highest point in the Estremadura province at 666 meters above sea level. It is a designated Protected Landscape area covering approximately 4,700 hectares. The range features diverse microclimates, hosting significant populations of birds of prey, including the Bonelli's eagle. Hikers utilize a network of trails that lead to the summit and offer views spanning toward the Atlantic coast and the Tagus River. The plateau houses the historical Real Fábrica do Gelo, an 18th-century ice production site. Vegetation transition is notable here, with Mediterranean scrublands giving way to holm oaks at higher elevations. The region is part of the limestone mountain chain that separates the Tagus and Sado basins. Its geographical prominence makes it a primary site for meteorological and environmental observation in central Portugal.

Wear sturdy, high-traction footwear as the limestone paths are frequently uneven and slippery.
Bring high-magnification binoculars, as birdwatching conditions are optimal from the upper ridge lines.
Carry a windbreaker even in summer, as temperatures at the 666-meter summit can be significantly lower than in the surrounding valleys.
Do not attempt to climb the slopes during high-wind alerts, as the exposed ridge is prone to dangerous gusts.
Stick to marked hiking paths to protect the fragile limestone soil and endemic flora; pack out all waste.
