Native California fan palms thrive in many locations but rarely in such numbers as in the canyons of the Indio Hills. Here, along a line where the San Andreas fault captures groundwater that nurtures the palms, is a wild parkland which is part of the adjacent Coachella Valley Preserve. The park contains some fine palm groves that include Hidden, Pushawalla, Briska, Macomber and Horseshoe palms. The nearest groves are relatively easy to reach from the trailhead and parking area 4-miles north of Indio.
Start at the Coachella Reserve parking lot. Start on the Macallum Trail, then Moon Country, keeping an eye out for the switchback trail to the left (to the south) at about 2 miles. Climb the switchbacks and you are on Herman Loop. Views are remarkable and rare for 360 degrees. Retrace your steps or carry on toward Willis and then the paved road. Drivers are basically texting idiots, so this is the only dangerous part of the trail.
A nice trail that connects to the Moon Country trail which, in turn, gives access to the Herman Hike Trail. I highly recommend finding the Herman Hike. It takes you up the nearby hill and reveals amazingly vistas of the incredibly eroded surrounding terrain.
