Calico Hills trailhead (view north)


This pleasant, 3.2-mile trail runs among low ridges, washes, canyons, and red sandstone boulders along the base of the brilliantly red Calico Hills. The trail generally traverses open country with interesting rocks, fossils, birds, rock art, contrasting vegetation types, and grand scenery all around. The Calico Hills Trail runs one-way from the Entrance Station to Sandstone Quarry. From that point, there are a number of trails that can be used to start, end, or make a loop using the Calico Hills Trail.

Watch Out

Other than the standard warnings about hiking in the desert, ...this hike is fairly safe, even for kids, but there are some short, steep scrambles through rocky areas near the Calico 2 parking area. Always be extra careful when you get high enough to fall and hurt yourself. Most of this trail is well groomed, relatively free of rocks, and makes for easy walking. Be careful crossing or walking on the roads.

While hiking, please respect the land and the other people out there, and please try to Leave No Trace of your passage. Also, even though this is a short hike, be sure to bring what you need of the 10 Essentials.

Getting to the Trailhead

This hike is located along the Scenic Loop Road in Red Rock Canyon National Conservation Area, about 30 minutes west of Las Vegas. Drive out to Red Rocks, pay the fee, then drive forward and turn left onto the exit road and left again into the Entrance Station Trailhead behind the fee booths. Park here; this is the trailhead.

Alternatively, park at the Visitor Center Trailhead or one of the three places along the Scenic Loop Road that access this trail system: Calico 1 Trailhead, Calico 2 Trailhead, and Sandstone Quarry Trailhead. These alternative trailheads add variety to the hiking possibilities and provide places to drop hikers off and pick them up later.

The Hike

From the Entrance Station parking lot (Site 895), the trails starts across the entrance road on the northeast corner of the 4-way intersection (Table 2, Waypoint 2). The trailhead is marked by a Calico Hills Trail System sign that gives mileages to several destinations.

From the trailhead (Wpt 2), the trail angles away from the Scenic Loop Road and runs east across a hillside for a short distance to an old road (Wpt 3). The trail turns left onto the old road and runs north towards the Calico Hills. The shrubby vegetation here is dominated by scattered Mojave yucca, Joshua tree, and creosote bush, set in a mix of low growing shrubs (including Mojave ephedra, blackbrush, and indigo bush) and brome grass.

The trail climbs over a low ridge and drops into a wash. Notice the contrast between vegetation on the ridge and vegetation in the wash. Not only is the vegetation in the wash more robust, but several species (including paperbag bush) can survive in the wash that cannot tolerate the dry, shallow soil conditions on the ridge.

The trail runs northwest up the wash a short ways, then curves north (Wpt 4) and starts up another low ridge. The trail runs across some exposed limestone slabs on the top of the ridge. The limestone is gray, and the dark brown protrusions on some of the limestone are fossiliferous materials. Most of these materials look like algal mats (bio-ooze), but there are some fossil sponges and a bit of crinoid rubble scattered about.

Continuing north from the fossil site, the trail descends to a gully and a trail junction (Wpt 5). The trail to the west runs 0.5 miles to the Visitor Center. The Calico Hills Trail continues north on a low ridge between Calico Hills Wash and the Scenic Loop Road, providing nice views of the escarpment to the west. The road is not close enough to be bothersome, and in places the trail runs just over the ridge so that you can't quite see the road.

Just south of the Calico 1 parking, the trail runs up along edge of Scenic Loop Road and passes a small trailhead sign about 60 yards south of the parking area (Wpt 7). This segment of the trail ends at the main Calico 1 trailhead, which is located on the east edge of parking area and marked with another Calico Hills Trail System sign (Wpt 9).

From the Calico 1 trailhead (Wpt 9), the Calico Hills Trail continues by running east for about 100 yards straight down the hillside towards Calico Hills Wash (heading towards the Calico Hills). At a trail sign just before the hillside drops more steeply into the wash (Wpt. 10), the trail turns north and runs along the hillside parallel to the wash for about 100 yards.

The trail drops into and crosses Calico Hills Wash (Wpt 11), staying close against the red sandstone boulders that form the base of the Calico Hills (several use-trails continue along the hillside; but stay against the rocks). With the relatively large amount of runoff from Calico Hills, there is enough water to support a dense thicket of shrub live oak, honey mesquite, catclaw acacia, paperbag bush, and desert almond in the wash. The area burned several years ago, but plants are growing back.

An alternative trail stays on the west side of the wash, but the main trail crosses the wash and runs steeply up the hillside (on a trail or on red slickrock) to the top of a low ridge that is about as high as the Calico 1 parking area. The trail then continues north along an east-facing sidehill, about halfway up from the bottom of the wash, which is nice because the hillside shields you from sights and sounds of the Scenic Loop Road. In a few minutes, the trail climbs back onto the top of the ridge, where you realize that there is another canyon between you and the road.

On the ridgeline, the trail runs across a bit of slickrock, and then hits red sandstone crags (Wpt 12). At the base of the crags, the trail turns left and drops steeply to the west in a little slickrock gully into what appears to be the bottom of the canyon, but actually is a gully among a jumble of red outcrops. The route naturally curves north and runs through a narrow canyon between red sandstone crags. When the canyon opens up a bit, the trail takes an odd jog to the west, over a low wall of red rock, and down another slickrock gully to the actual bottom of the canyon.

In the bottom of the canyon, the trail stays on the east side of the wash (although there are several use-trails on the other side) until the trail is just below the Calico 2 parking area. At that point, the trail takes a jog to the west and crosses the wash under a single-leaf pinyon pine growing in the bottom of the wash (Wpt 13). The pine is flanked by thickets of shrub live oak and ashy silktassel.

Calico Hills Trail The trail continues north along the west side of the wash for another minute or so to a trail junction on a switchback (Wpt 14) where you can still see Calico 2 above you. A use-trail continues up the canyon, while the main trail switchbacks to the southwest and starts up towards the parking area. The trail quickly passes another trail junction (Wpt 15) where a use-trail heads up the canyon and the main trail continues towards Calico 2. At a third trail junction, this one marked with a trail sign (Wpt 16), one trail runs up to the Calico 2 parking area (Wpt 17), while the other continues north to Sandstone Quarry.
Calico Hills Trail

From the trail junction (Wpt 16), either walk the short distance (about 150 yards) to the Calico 2 parking area or continue north to Sandstone Quarry, which is about 1.2 miles north. If you hike up to Calico 2 (Wpt 17), which has another Calico Hill Trail System sign, you can walk back to the Entrance Station on the road.

From the trail junction with the sign (Wpt 16), the Calico Hills trail continues north towards Sandstone Quarry. The trail winds around the hillside, climbing at a moderate grade for about 75 yards to an unmarked junction (Wpt 18) where a use-trail comes in from the south (it connects back with the trail to Calico 1).

Calico Hills Trail
Archaeological site (view north)
From the unmarked trail junction, the trail runs north, working up over a red slickrock ridge, angling down the other side of the ridge, and running down into the bottom of a little hidden canyon. The effects of differing levels of soil moisture are clearly evident here. The vegetation along the wash includes two fairly tall single-leaf pinyon pine (one dead), lots of shrub live oak, some Stansbury cliffrose, few other species of shrub crowded into the bottom of the canyon. In contrast, the adjacent hillside is vegetated primarily with blackbrush and scattered creosote bush and Mojave yucca. This area burned too, but the vegetation is slowly growing back.
Calico Hills Trail

Towards the far end of the hidden canyon, an enormous boulder and several other huge boulders clustered around lie out away from the cliffs (Wpt 19). Native peoples used this area and left rock art pecked into the black desert varnish patina. Some of the petroglyphs are unusual in that they are located on the top surfaces of the boulders -- please don’t walk on these rocks as you will hasten erosion and loss of the artwork.

Calico Hills Trail

From the rock art site, the trail continues up the canyon climbing the hillside, crossing over a red-rock ridge, and running up and across more red slickrock. The trail runs north, winding along the hillside intermittently on dirt and slickrock, but always staying on the hillside above the fairly narrow red-rock gorge. The trail eventually runs to the top of the hillside and crosses a low ridge (Wpt. 20), providing the first view of Sandstone Quarry. Through this section, several use-trails branch off, but the main trail always stays high on the hillside

Sandstone Quarry
Sandstone Quarry area (view north)

From the ridge, the trail runs down to the Sandstone Quarry trailhead (Wpt 21), which is located on the Sandstone Quarry access road, about 50 feet before the parking lot. The vegetation at the trailhead is similar to that in the canyon: lots of shrub live oak, yerba buena, and manzanita along base of the cliffs where the soil catches runoff from the rocks, and blackbrush, creosote bush, and yucca on the flats.

From Sandstone Quarry, consider hiking up to Calico Tank or use the paved road to walk back to the trailhead.
