What to expect on the Barker Dam Trail

What to expect on the Barker Dam Trail

Barker Dam Trail is a short loop over varied desert terrain, with a dam and rock art site along the way. The route passes monzogranite boulders, Joshua trees, other desert plants and sandy washes. Interpretive signs describe the dam and the area's plants, animals and people.

The surface includes compact dirt and granite boulders, and some sections require stepping over or around rocks. The hiking time is 30–45 minutes; another estimate gives a range of 30–60 minutes, so allow for the longer estimate if you want time to pause at the interpretive signs.

Built in 1900 and associated with early ranching in the park, Barker Dam was listed on the National Register of Historic Places in 1975. The reservoir is typically dry most of the year, but may fill after heavy rainfall.

How do you get to Barker Dam Trail?

From the North Entrance, follow the NPS directions to reach the Barker Dam parking lot. After the signed junction, continue about 11.9 miles toward Hidden Valley, turn right at the Barker Dam/Keys Ranch sign, then follow the road about 1.5 miles to the lot.

The trailhead has parking for cars, buses and RVs, as well as restrooms, including an accessible restroom, and a vault or composting toilet. Parking can be scarce during the peak period from September to May.

Echo T parking lot, west of the Barker Dam lot, is an alternative. For broader planning, read how to plan a Joshua Tree National Park visit from Twentynine Palms.

If you want a longer walk, the Echo T Connector Trail adds about 0.6 mile to the Barker Dam loop, making the combined route 1.7 miles. The trail is open year-round, but access and conditions can change; check the official site before you go.

Water, shade and desert preparation

Water, shade and desert preparation

The trail has minimal shade, and summer temperatures can exceed 100°F. Carry at least one liter of water per person for this hike, protect yourself from the sun and wear footwear suited to rocky terrain. For a full day in the park, NPS visitor guidance recommends at least one gallon of water per person per day.

Rocks may be slippery when wet. Avoid drainage areas during and after severe weather and thunderstorms because of flash-flood danger. Most of the park has no cell phone coverage, so plan around limited connectivity.
