Getting There
To visit Guerrero Viejo (Old Guerrero), cross the border at the Falcon Dam on your way to Nuevo Guerrero. Take Highway 2 North along the border travelling West of the reservoir. Watch for hand-painted signs pointing to a dirt road which passes through several small ranchitos, and the ruins of old stone structures, gradually descending to Old Guerrero behind a gated entrance. The road is about 10 miles long, but will require significant time as you may have to open and close gates, wait for livestock to move off of the road, etc.
At the site, there may be a gate attendant. If so, you must pay to enter, usually just a few dollars. The admission charge is helping to fund the restoration of the church.
The Federales frequent the little village, once a ghost town, as there is renewed interest and increased visitation from the outside world. You will also likely find Federales check points on Highway 2, so you will need your valid auto insurance, identification and a passport. Be aware that water levels fluctuate and some areas may be inaccessible at times.
