At the pond, keep an eye out for pupfish, dragonflies, tadpoles, and even the occasional coyote!

Next to the Kris Eggle Visitor Center is a 1/10th of a mile paved nature trail that loops by a small pond and showcases native Sonoran Desert plant life. The trail begins by the parking lot and loops around to the back of the visitor center.  

Pets are allowed on this trail. 

A Refuge for Endangered Quitobaquito Pupfish

The visitor center pond, affectionately known as “La Ciénaga" or "desert oasis," is home to the endangered Quitobaquito pupfish. This small fish is only found in Quitobaquito Springs, in the southwest corner of the monument, and in the Rio Sonoyta, a small Mexican river drainage directly south of the international border. Since this unique fish naturally exists in only one location within the United States, a second habitat was created and set aside as a refuge for this endangered species. This pond was designed and built in 2005 by 160 science students from Ajo Middle School.

If you plan on spending time in the park outside of the visitor center area, a general entrance fee is required and can be paid in the Kris Eggle Visitor Center or at a self-registration pay kiosk. 
The trail has one entrance by the back door of the visitor center and loops back around the parking lot, near the Kris Eggle Memorial.
