First off...no need to criticize the weakness of this site design...I already know 

These were made up from some Google Maps images and based on directions given to me by a lady who works at the Griffith Park Merry-Go-Round so hopefully they are accurate!! 

Exit the 5 at Los Feliz  (If you are on the 5 South, use the Los Feliz (West) offramp and merge right onto Los Feliz.  If you are on the 5 North, exit Los Feliz and make a left. 

Proceed down Los Feliz and enter the park by making a hard right on Crystal Springs Dr. as shown below.  On the map, it looks like this is the first opportunity to make a right after the freeway.

 

 Head up Crystal Springs Dr. a ways towards our destination.  According to the lady I talked to, we'll need to make a left at the 2nd stop sign and head into the Carousel parking lot.  There are some additional instructions on this next pic.
