CAUTION! If your GPS tells you to turn off Cowan/Lorraine Rd. (Hwy 605) on to any street other than Hillcrest Rd. you are being mis-directed. This seems to happen most often with devices using Apple Maps.
From Hwy 90 (E Beach Blvd):
Turn north onto Cowan/Lorraine Rd. (Hwy 605)
Go over the first bridge, through the following stop light, and take the second right before the draw bridge onto Hillcrest Rd.
You should see a green sign with white letters directing you to the Center for Marine Education and Research.
