101 San Antonio Road, Petaluma, CA 94952

NOTES –
Both Google and MapQuest direct you to the front gate as though that is your final destination. After you drive through the gate you'll need to follow the signs to get to EarthRise and the IONS campus, which is down the road and up the hill to your left.

If you look at Google driving directions you have the added benefit of real photographic images (at a dry time of year) that might be helpful.

Please see below for details about getting off the freeway at the end of the trip, including important safety information for northbound travelers.

Driving Directions Southbound from Sonoma County

Hwy 101 Southbound from Petaluma, Santa Rosa, and points north:

• Driving south 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. 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 driving to IONS from the south (driving north on 101), you can choose from two options for getting off the freeway:

Option 1: Turning left off of the northbound freeway. (This is not an “exit,” but rather a left turn across lanes of oncoming freeway traffic.)

if you choose this Option 1, you'll need to be very careful! For your safety we recommend following Option 2, below.

• Driving 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 three-tenths (3/10) 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.

Option 2: Driving past IONS and turning off at the next Petaluma exit where you can turn around to 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 will take you 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. Drive past that sign and look for the larger San Antonio Road sign about a half a mile down the highway.
