Climate, Geography, Setting

Located at the extreme western edge of the Sonoran Desert, these two parks experience extremely hot summers and mild winters. For this reason, the parks are closed between June 1 and September 1 each year.

Both parks are located in Earthquake Valley on California's County Road S-2 between SR 78 and Intertate 8. These two parks are completely surrounded by the Blair Valley Region of Anza-Borrego Desert State Park.



For the Native Americans who lived here for thousands of years, for Spanish conquistadors, for explorers and soldiers such as Kit Carson and General Stephen Kearny, for emigrants in the early part of this century who still traveled by wagon, Vallecito has always been a green refuge in an often harsh land.

Countless generations of Native Americans camped and lived at Vallecito, because of the natural springs along the earthquake fault here. But a single generation of 19th Century Americans left indelible impressions. One example, the stage station, is testimony to the most dynamic decade of this area's history. First used as an army supply depot, then as a rest stop on the "Jackass Mail" between San Antonio and San Diego, the building was busiest during the lifetime of the Butterfield Overland Stage (1858-61). The stage line carried mail and passengers over the 2,800 miles separating Tipton, Missouri and San Francisco in 25 days. It was said to be the longest stage ride in the world. Note sometimes it is closed for the summer - Phone Number: 760.765.1188

Vallecito Stage Station

Stage stations scattered along the route offered the weary passengers a brief meal and rest as the horses were changed. Then it was on to the next stop on the 24-hour-a-day journey. Vallecito was a favorite such station, since it was the first place with greenery that travelers saw after crossing the hostile desert west of Yuma. But the Civil War ended the southern mail route, and Vallecito went into a slow decline.

In 1934 San Diego County purchased the crumbling building and surrounding land, and rebuilt the station using original materials. But it's not only human history that is preserved here. The extensive vegetation in the small valley supports abundant wildlife, including foxes, coyotes, mountain lions, and many reptiles. Birds are especially attracted to the mesquite and acacia thickets; among the avian residents are desert specialties such as cactus wrens and black-throated sparrows.

Agua Caliente

Centuries ago, the Kumeyaay Indians were initially attracted to the springs at what we now call Agua Caliente ("hot water" in Spanish). Spanish explorers, miners, then pioneers, soldiers and prospectors eventually made their way here as well.

The seismic activity that long ago shaped the Tierra Blanca Mountains to the west and created the fault that runs beneath both parks, also enabled water to come to the surface and form the park's natural springs.

A wide variety of wildlife is attracted to the springs, including foxes, Coyotes, Bobcats and Mountain Lions. The abundant water supply also supports lush plant life, such as mesquite, willows, Washingtonia palms, and acacias. Depending on the season's rainfall, wildflowers and succulents some times put on a colorful show in early spring.

Pet Fees: Pets are $1.00 per night (note that dogs are not allowed at Quail Gardens or Volcan and Santa Ysabel Open Space Preserves). Horses are $2.00 per night at Sweetwater Summit, collected at the park upon check-in.

Agua Caliente

Two naturally fed pools provide different ways of enjoying Agua Caliente's hot springs. A large outdoor pool is kept at its natural 96°, and an indoor pool is heated and outfitted with Jacuzzi jets. Spring-fed, warm showers are also available.

A small picnic area is perfect for day users. Hiking trails, horseshoe pits, shuffleboard courts, and a children's play area offer plenty to do in the 910-acre park.

Surrounding both Vallecito and Agua Caliente is Anza-Borrego Desert State Park, the largest state park in the U.S.

The Saguaro Video
The Saguaro often begins life in the shelter of a "nurse" tree or shrub which can provide a shaded, moister habitat for the germination of life. The Saguaro grows very slowly -- perhaps an inch a year -- but to a great height, 15 to 50 feet.

The Desert Food ChainDesert Food Chain Video
A food chain constitutes a complex network of organisms, from plants to animals, through which energy, derived from the sun, flows in the form of organic matter and dissipates in the form of waste heat.

Prickly pear cactus Video
Prickly pear cactus are found in all of the deserts of the American Southwest. Most prickly pears have large spines on their stems and vary in height from less than a foot to 6 or 7 feet.
