The park's signature marked trail, threading between eroded rhyolite columns up to 60m tall that gave the Sierra de Órganos its name and its long career as a backdrop for Western films.
El Campanario is the best known of the two marked trails in Sierra de Órganos National Park, a small but visually dense protected area in the northwest corner of Sombrerete municipality in Zacatecas, near the Durango state line. The park takes its name from the eroded rhyolite formations that stand in ranked columns resembling organ pipes, some reaching 60 metres, sculpted over millions of years into red, orange and brown towers that shift colour through the day. El Campanario, named for a bell-tower-shaped formation partway along the route, is a loop of roughly 3.4 km that weaves directly among the columns rather than skirting them, making it the most immersive short walk in the park.
The park sits about 21 km northwest of the town of Sombrerete, reached by a paved road from town that turns to graded dirt for the final stretch; a small visitor centre near the entrance holds geology and film exhibits, since the park's other claim to fame is its decades-long use as a filming location for Western productions, including Geronimo (1962) and Bandidas, valued for landscapes that read as the American Southwest. There is no public transport to the entrance, so a private vehicle or arranged taxi from Sombrerete is required, and a modest park entrance fee applies at the gate.
Underfoot the trail is packed dirt and exposed rock with occasional short scrambles between boulders, easy enough for most fitness levels but engaging enough to reward slow walking. Shade is minimal, limited to the shadow cast by the columns themselves at low sun angles, so early morning or late afternoon both improve comfort and produce the best light on the red-orange stone. Picnic areas, basic camping and restrooms sit near the visitor centre, but nothing is available once the loop leaves that cluster, so water should be carried for the full circuit even though it is short.

Highlights
- Close walking among eroded rhyolite columns up to 60m tall, the formations that give the park its name
- The bell-tower-shaped rock landmark that gives El Campanario its name, partway around the loop
- A landscape used for decades as a Western film backdrop, including Geronimo (1962) and Bandidas
- A small visitor centre with geology and film-history exhibits near the trailhead
- Dramatic colour shifts across the red, orange and brown stone through the day
Tips for visiting
- Visit at sunrise or the last two hours before sunset, when low light rakes across the columns and produces the strongest colour and shadow.
- Carry water even though the loop is short; nothing is sold beyond the visitor centre near the entrance.
- A high-clearance vehicle is not essential but helps on the graded final approach road, especially after rain.
- Pair the walk with the shorter La Cueva del Toro trail on the same visit, since both trailheads share the same access road.
- Weekday visits are noticeably quieter than weekends, when the park draws day-trippers from Zacatecas city and Sombrerete.
- Bring a wide-angle lens or phone if photographing the columns; standing close to the rock is part of what makes the loop distinctive.
When to visit
October to April gives the coolest temperatures and clearest air. Early morning and the last two hours before sunset bring the strongest light on the rock columns and the most comfortable walking temperatures.
Accessibility
The trail surface is packed dirt and exposed rock with short scrambling sections between boulders, and it is not wheelchair accessible. The visitor centre, picnic areas and restrooms near the entrance are on level ground.
Frequently asked questions
Is there an entrance fee for Sierra de Órganos National Park?
Yes, a modest per-person fee is charged at the park gate, in addition to which no further charge applies to walk El Campanario or the park's other marked trail.
How difficult is El Campanario?
It is an easy loop of about 3.4 km with only short scrambles between boulders and no sustained climbing, suitable for most fitness levels and manageable in about an hour.
Can the park be reached without a car?
Not practically. No public bus serves the park entrance, roughly 21 km northwest of Sombrerete, so a private vehicle or a taxi arranged as a round trip is required.
Why was Sierra de Órganos used for Western films?
The columnar rock formations and open high-desert terrain closely resemble the American Southwest, which led Mexican and American productions including Geronimo (1962) and Bandidas to film here across several decades.
