It goes through the western side of the of Sierra Negra until the equestrian trail ends then continues to the interior of the caldera by a high-inclination slope and finally reaches a place where there are various sulfur fumaroles.
Part of the trail is used by local hunters, who enter to hunt, mainly wild pigs and cattle. Galapagos National Park personnel also use this site to go to different places of work, where they do conservation work.
During the rainy season on the Sierra Negra volcano, an intense fog is present; it reduces the observation of the landscape in most of the trail. By contrast in summer, you have the opportunity to enjoy the spectacular scenery of this volcano.
