A steady climb up the rocky, cactus-studded flank of Cerro del Muerto, the reclining-figure mountain that dominates the western skyline of Aguascalientes city, ending on a ridge with sweeping views over the capital and the surrounding highland plain.
Cerro del Muerto is the mountain every resident of Aguascalientes city sees from their window: a long reclining silhouette on the western horizon that the range's name, the Dead Man, describes exactly. The Picacho Trail is the standard way onto it. The trailhead sits at the top of Paseo La Herradura in Fraccionamiento Villas de Nuestra Senora de la Asuncion, on the western edge of the city at roughly 2,000m, where a dirt track leaves the last row of houses and starts climbing immediately. There is no bus service to this point, so most hikers arrive by car or taxi and park on the residential street; there is no formal lot, no gate and no permit, and the mountain is a protected natural monument administered at the state level rather than a fee-charging park.
The route runs about 6.9 km round trip with roughly 465m of gain to the Picacho ridge, with the crest of the range reaching around 2,650m. Nothing on it is technical, but the grade is relentless from the first ten minutes and the surface is loose volcanic rock and decomposed granite that rolls underfoot, particularly on the descent. Vegetation is low semi-desert scrub, nopal, huizache and columnar cactus, which means shade is essentially absent for the entire climb. The line is braided in places where hikers have cut switchbacks, so the visible path is not always the best path; the general rule is to keep gaining height toward the notch below the rocky Picacho outcrop.
Landmarks come at useful intervals. A small shrine and a set of communication masts mark the first significant flat, roughly a third of the way up, and this makes a sensible turn-around for anyone finding the grade harder than expected. Above it the route steepens across an open rock apron before topping out on the ridge, where the view opens over the entire capital, the Valle de Aguascalientes and, on clear winter mornings, the outline of the Sierra Fria far to the north. There are no huts, no shelters and no water sources anywhere on the mountain, and no reliable shade in which to wait out a storm, so the whole day's water has to be carried from the city.

Tips for visiting
- Start at first light: the trail has no shade at all and the climb becomes punishing after about 10am from March onward.
- Carry at least 2 litres of water per person. There are no springs, taps or refuges anywhere on the mountain.
- Trekking poles pay for themselves on the descent, where loose volcanic gravel over hard rock is the main injury risk.
- The masts and shrine at the first flat make a natural turn-around point for anyone struggling with the sustained grade.
- Parking is on public residential streets at the top of Paseo La Herradura; leave nothing visible inside the vehicle.
- Afternoon storms between June and September build fast over the ridge, which is fully exposed with nowhere to shelter.
When to visit
October to March offers the coolest temperatures and the clearest views over the city and the valley beyond. Early morning starts are strongly preferred year-round, both to avoid the unshaded heat and because haze over the capital thickens through the day.
Accessibility
The trail is not wheelchair or stroller accessible at any point. It is an unsurfaced mountain path on loose volcanic rock with a sustained steep grade, no handrails and no graded sections. The residential streets at the trailhead itself are paved and level.
Frequently asked questions
Is there an entrance fee or permit for the Cerro del Muerto Picacho Trail?
No. Cerro del Muerto is a state-protected natural monument with open access and no ticket office, gate or permit requirement. Hikers simply walk in from the residential streets at the top of Paseo La Herradura.
How long does the Picacho Trail take?
Most hikers complete the 6.9 km round trip in three to three and a half hours, including a stop on the ridge. Slower walkers should allow four hours, as the descent over loose rock is not much faster than the ascent.
Can the trail be reached by public transport?
Not directly. No city bus route serves the Paseo La Herradura trailhead, so hikers use a car, taxi or ride-hailing service from central Aguascalientes, a journey of around 20 minutes.
Is water available along the route?
No. There are no water sources, taps or refuge huts on the mountain. Everything needed for the day must be carried from the city.
Is the trail suitable for children?
Older children who are used to walking uphill manage it, but the sustained grade, loose footing and total lack of shade make it unsuitable for small children. The shrine and masts at the first flat are a good short alternative.
