Top 11 Adventures on San Diego Route S2 (Pony Express)

Have you ever been interested in the old pony express? Then exploring San Diego County Route S2 might be the perfect adventure for you.

S2 is approximately 65 miles long and goes from Ocotillo to the Hwy 79 junction at Warner Springs. It takes you a little over 1:20 minutes to travel the entire route without any stops.

Most of the road runs through the Anza-Borrego Borrego Desert State Park. The park is California’s largest state park and encompassing 640,000 acres.

For years, I drove on S2 and never gave it any consideration at all. The landscape is beautiful, but I was always more interested in getting to my destination as quickly as possible.

One day I decided to stop over at Vallecito County Park because I needed to make a phone call.

While I was at the park, I noticed an old adobe building, so I decided to investigate.  I found out that the old adobe building was an old pony express stagecoach stop. I never knew that the road I traveled on so much was an old pony express route.

I learned that the actual name of the road is the Great Overland Stage Route. Knowing this made me fascinated about what else is around County State S2.

So, I decided to investigate and see what else was around S2, and to my amazement, I found some fantastic adventures.

I learned that S2 offers everything from natural springs, hiking, mud caves, great BLM camping, history, and fantastic wildlife. The history of the road I find fascinating, and I hope you do too.

#3 Bow Willow Creek Campground

The campground is located by Bow Willow Canyon and a few miles off S2. Cahuilla Indians used the canyon as they made their way to their summer home in the Laguna Mountains. In the hills above Willow Campgrounds, they left pottery and other artifacts.

Various hiking trails originate at the campground, including Mountain Palm Springs, Totote Bowl, and Rock House Canyon Loop.

A complex of 6 spring-fed oases near the Tierra Blanca foothills provides a lush habitat for various plant and animal species, including the California Fan Palm.

A small sign near milepost 47 marks the start of the dirt road to the campground.  There is a $15 fee per night.

#4 Mount Palm Springs

Mount Palm Springs is home to six groves of palm trees. These palm trees sit on top of underground water sources in a shallow ravine, forming oases with grass, bushes, and cool air.

The largest group is Palm Bowl Grove which can be accessed from a 1.2-mile trail up the ravine. The other four groves are located throughout the area inside canyons.

A small sign near milepost 47 marks the start of the short trip to the Mountain Palm Springs trailhead.

#5 Arroyo Tapiado Mud Caves

One of the fascinating points of interest in the Anza-Borrego Desert State Park is the system of caves known as the Arroyo Tapiado Mud Caves.  Arroyo Tapiado, translated from Spanish, means “walled wash.”  The mud caves are found along the walls of this wash canyon. The caves are one of the most extensive mud cave systems in the world. It contains approximately 22 known caves and nine slot canyons.

Agua Caliente County Park and campground provide the perfect escape for any van or RV nomad who wants to explore the Anza Borrego State Park and explore the surrounding area.  The main activities at the park are hiking, lying by the pools, bird watching, photography, and stargazing.

The official trailhead is located off route 79 in Warner Springs, but side trails lead from S2 but are more difficult to find.

#11 Warner-Carrillo Ranch House

At the end and beginning of R2 in Warner Springs is the Warner-o Ranch House. The house was built in 1857 by Vincenta Carrillo, a prominent early Californio woman rancher, was a Butterfield Stage Stop from 1858 until the beginning of the Civil War in 1861.

The ranch house plays a leading role in the history of the American West. It represents Mexican and American culture contact during the Mexican Republic; the Frontier period of the westward migration, and the Gold Rush, and the cattle ranching industry from 19th century Californio to the 20th century to today.

Its importance as the southern emigrant overland trail and Butterfield Stage Station cannot be overstated. It was designated as a National Historic Landmark in 1962.

It still sits a vast expanse of open space, a setting virtually unchanged from the mid 19th century.
