From the North:

• Take 101 southbound through Eureka, and take the Tompkins Hill Road exit. 
• Make a right at the stop sign (don't worry, there's only one). 
• Continue south along Tompkins Hill Road, and you will pass CR's North entrance on your left.
• The CR Main entrance will appear on your left almost immediately afterward.

From the South:

• Take 101 northbound on your way to Eureka. 
• You will pass the College on your right.
• The next exit is Tompkins Hill Road.  Take this exit, and turn right at the stop sign when you reach it.  
• You will pass CR's North entrance on your left, and will almost immediately be presented with the Main CR entrance, again to your left.
• The South entrance is where you will find the Security/Information building, just as you enter the College.
