At about the ninth mile marker of the Montezuma junction to Borrego Springs Trip is a hike to Pena Spring. The left fork from the entrance kiosk leads about a half mile up to a roadhead, circling a desert plum, from which a hiking trail drops to the north.
Ground water appears in the descending trail after a half-mile.
Pena Spring, a year-round source of abundant water, is through thick bushes to the left. The excellent water source attracts a large number of birds and other wildlife. Deep morteros may be found in bedrock to the right. This area has clearly been attractive to people for a very long time. The spring is named for Pena Paroli.
