Montevideo is one name given to the "Indian Paintings", or Pinturas Rupestres. There are now signs marking the turnoff, which is the same
one as for Mission San Borja. Take the road out of town, as if you would be returning to Hwy. 1. Approximately 15 miles from town, you will see a sign marking the turnoff to the Mision & the Pinturas Rupestres. You can inquire locally at the town's Museo for more information.
Four wheel drive is not necessarily needed, although there are areas of soft sand and protruding rocks, so ground clearance is important. There is some extremely soft sand when you reach the area where the paintings are located, and it's easy to get stuck. Use common sense and care when visiting the area and enjoying its historical sites.
