If you're up north of Powell Road, take Powell Road west to Riverside Drive (you can't miss it - Powell Road dead ends into Riverside Drive). Turn left on Riverside Drive and go south. The Safari Golf Club is just south of the Columbus Zoo, and will be on your left.
You will pass both the main zoo entrance (on your left) and Glick Road (on your right) before you reach the entrance to the Safari Club (on your left).
Take 270 and exit at Sawmill Road (Exit 20).
Go north on Sawmill Road (you'll pass a McDonalds on your right) to Hard Road. About a mile up the road, there's a small strip shopping center on the right - just before you reach Hard Road. You'll see a brown and white sign directing you to the Columbus Zoo and Wyandot Lake. That's a CVS Pharmacy at the corner of Hard and Sawmill.

Hard Road will dead-end into Route 257 (Riverside Drive).
Turn RIGHT on to Route 256 (Riverside Drive) and head north.
The zoo is about 3 miles north on Riverside Drive. The entrance to the Safari Club is about 1/4 mile before you get to the zoo. You'll know you're getting real close to the Sarfari Club entrance when you see a sign up over the road that indicates the traffic light for Glick Road is just ahead. My eyes aren't what they used to be - I can see the overhead sign, but I can't read what is on it!

The entrance to the Safari Club is on the right side of Riverside Drive. It is just past the pole holding that overhead sign, and before you get to that big tree on the right.

Turn RIGHT into the Safari Club driveway, and follow the signs.
If you come to the main entrance to the Columbus Zoo, you've gone too far, and will probably need to drive another half mile north to Powell Road in order to turn around (turn right on to Powell Road, and then immediately turn left into the little cross-over, which allows you to turn left on to Powell Road and then left on to Riverside Drive). The Safari Club entrance is south of Glick Road, just past where the divided highway ends.
