I decided to post this google map I did of the Long Trip around Diamond Head through the eastern shore and around to to the North Shore with return through the middle of Oahu. If you want to go directly to the surfing areas like Bonzai Pipeline, you also can reach the North Shore more directly by just taking the central road back and forth. But the eastern shore is spectacular too. Click at the top of link to include a large map. I editited it to start and end at the Sheraton Waikiki.
