Hike the exciting Calcite Mine Trail and Narrows

Tom’s Experience hiking to the Calcite Mine and Narrows:

The Calcite Mine and Narrows is a very hot hike in the Anza Borrego Desert State Park. You follow a dirt road for the first mile or so on this hike and may have to share the road with 4-wheelers.

The road starts off fairly gentle but eventually gets very rough and rocky so I’m glad I didn’t try to bring my car. After about 1.4 miles turn left and head up a canyon that is only open to hikers.

The canyon begins to narrow and there are a few easy obstacles that you need to climb over in order to progress up canyon.

Eventually you reach the mine. I wasn’t able to find the actual mine but there was a ton of discarded calcite below my feet. Return the way you came and if you would like, you can continue heading down canyon rather than following the 4wd road you came up.

It is easy to get lost in the canyon and you may have a difficult time finding your way back to the car if you take the canyon down but it is definitely more scenic than the road. The narrows on this hike are pretty cool but they are very short.

The calcite from this mine was used in world war 2 in the precision bomb sights and anti-aircraft weaponry. Dogs are not permitted on any trail in the Anza Borrego Desert Park.

Tom’s Rating:

Trail Info: This is a 4-mile long hike to an old Calcite Mine from world war 2. The trail is not marked well and it is very easy to get lost in the desert. I would recommend taking a map or a very reliable GPS because it is easy to get lose your way in the desert canyons. From Christmas Circle in Borrego Springs, drive east for 4.3 miles on Palm Canyon Drive. The road bends north, becoming Pegleg Road. After 2.4 miles, the road turns east onto Borrego Salton Seaway (Route S22). Drive another 12.4 miles to the trailhead. There is a large turnout on the north side of the road near mile marker 38. Calcite Mine Trail begins 0.2 miles to the east (marker 38.2). Directly across from the trailhead, there is a smaller pullout on the south side of the road near emergency call box 382. Park in either spot and walk to the display panel at the start of Calcite Mine Road, which describes the history of Calcite Mine.
