High Coniferous Forest
The Puerto Vallarta region’s rarest, least accessible vegetation zone is the high coniferous forest, which swathes the slopes of lofty peaks, notably the Nevado de Colima (elev. 14,220 ft/4,325 m), on the Jalisco-Colima border. This pristine green alpine island, accessible only on horseback or by foot, nurtures stands of magnificent pines and spruce, laced by grassy meadows, similar to the higher Rocky Mountain slopes in the United States and Canada. Reigning over the lesser species is the regal Montezuma pine (Pinus montezumae), distinguished by its long, pendulous cones and rough, ruddy bark, reminiscent of the sugar pine of the western United States.
