If you'r not familiar with Raleigh, the I-40/I-440/US 1, it can be tricky.
IF you are coming on I 40 EAST, you will see these signs.
Take Exit 293 off I-40. (I40EAST11)
Just as you exit you will see (140EAST22) Sorry about the focus:
Get in the right hand off ramp lane.
Now here's the tricky part:
You have to immediately look to merge in the left lane onto US 1. Traffic from US 1 may be trying to take the off ramp onto Walnut Street. (US1South picture)
Take Hwy US1 South through Cary and Apex. Take the New Hill exit (Exit 89) off Hwy US1. At the top of the ramp, turn left onto New Hill- Holleman Road and go approximately 3 miles and the park entrance will be on your right.
