The dense vegetation of this remote countryside, and the difficulty traveling through it, gave the reserve its name: the Mountain of the Missing Spur (a cowboy's spur was presumably pulled off by a recalcitrant bush). The area is also home to the island's largest remaining rainforest, as well as loads of other endemic species, many on the verge of extinction.
A guide is mandatory to access the park; tours can be arrange through the Fundación Loma Quita Espuela.
The reserve is accessibly only with a 4WD, on a rough road 15km northeast of San Francisco de Macoris.
