DRIVING Directions TO IONS

COMING SOUTH
- From Sonoma County:

From Hwy. 101 Southbound from Petaluma, Santa Rosa and beyond:

• Heading southbound on Hwy. 101, the San Antonio turn off is 2.5 miles past the “Gas & Shop” gas station on the 101 corridor. At the large green highway sign indicating San Antonio Road, turn right.*
• This is a sharp turn that will put you onto San Antonio Road going in a northerly direction.
• The gate to IONS will be on your left just about 3 tenths of a mile down the hill. There is a sign for the Institute of Noetic Sciences. Drive through the gate and follow the signs to the Institute.

*Going South on 101 you may notice a small street sign that says "San Antonio Road" at the bottom of a hill. Just drive past that sign and look for the larger San Antonio Road sign about a half a mile down the highway.

Important Safety Note about Driving to IONS from the south: If you're coming to IONS from the south (driving north on 101), you can choose from two options:

#1. Turning Left off of the Freeway:

NOTE: if you choose this option you'll be turning left and driving across lanes of freeway traffic and you need to be very careful! You can avoid this by following option #2, below.

• Heading NORTH on 101 you can make a left turn off of the freeway at San Antonio Road. The San Antonio Road exit is 4.7 miles north of the last Novato exit (San Marin Drive). If you choose this option, BE PATIENT AND WAIT FOR A LARGE BREAK IN THE SOUTHBOUND TRAFFIC, SO YOU CAN CROSS THE FREEWAY SAFELY.
• Once you cross the freeway you'll be on San Antonio Road going in a northerly direction.
• The gate to IONS will be on your left just about 3 tenths of a mile down the hill. There is a sign for the Institute of Noetic Sciences. Drive through the gate and follow the signs to the Institute.

#2. Driving past IONS and turning around in Petaluma so you can approach from the north and avoid having to drive across highway traffic:

• Take Highway 101 North through Novato until the Petaluma Blvd. South exit
  — This is taking you up a little north of IONS.
• Exit at Petaluma Blvd. South and follow the signs to 101 South, toward San Francisco.
  — With this step, you're turning around to head back south on 101.
• Approx. 2.5 miles past the “Gas & Shop” gas station, turn right at the large green highway sign indicating San Antonio Road.*
• This is a sharp turn that will put you onto San Antonio Road going in a northerly direction.
• The gate to IONS will be on your left just down the hill. There is a sign for the Institute of Noetic Sciences. Drive through the gate and follow the signs to the Institute.

*Going South on 101 you may notice a small street sign that says "San Antonio Road" at the bottom of a hill. Just drive past that sign and look for the larger San Antonio Road sign about a half a mile down the highway.
