Depart San Miguel on Zacateros, which turns into Ancha de San Antonio and passes the Instituto Allende. Go straight across the intersection with the Salida a Queretaro—57 and continue on for 6 miles. At this point, you will see a sign for Guanajuato. Go right. Follow this road for about 24 miles until it Ts with another road. Again go right, following the sign to Guanajuato.
In about 12 miles, you will pass through the little pueblita of La Sauceda. Take care over the topes (speed bumps). Soon you will be on the outskirts of Guanajuato where you will come upon a traffic circle with a large statue of a woman in the center. Go past the circle heading to Guanajuato. Get into the right lane. Soon you will pass under a pedestrian bridge and an exit to Guanajuato. Take this exit to the right. This road leads through a tunnel into Guanajuato. Follow the signs to Dolores Hidalgo.
You’ll travel into town and pass the Hotel Real de Minas on your left, and a park with stone frog statues further up on the right. Pass the park and straight through the next traffic circle and under a large stone arch.
The next left is tricky. The road veers to the right into the underground tunnels. DO NOT GO RIGHT! Instead, go left up a small hill that has an immediate small traffic circle stay to the right around the traffic circle and go into the tunnel. At the end of the tunnel is a T intersection (Alhondiga Street). Take a left to the next traffic circle. Go around the circle - and head up the hill. The signs should all be directing you to Dolores Hidalgo/Camino Real/Valenciana.
At the end of this street is the Hotel Parador Camino Real. Stay to the right around the hotel and follow the road up the hill to La Valenciana. The road is curvy, so take your time.
Pass through the small plaza and travel further up the hill. You’ll see a sign on the right CIMAT ENTRADA NORTE. Go LEFT onto the little street and take the fork to the right. On your right are the ruins of the Guadalupe Mine, with its great flying buttresses. This short road ends at CIMAT, a large math research center. Turn left when you reach the gate for the CIMAT parking lot.
Casa Estrella is the first property on the right. We share a fence with CIMAT.
IF ALL ELSE FAILS, ask someone, “Disculpe, donde está CIMAT?” Once they have pointed the way, you can’t miss us!
