There are plenty of sight seeing opportunities on Oahu, as Oahu is a small island and it's possible to drive around the island in a day. We would drive around the island several times and also drive to different tourists spots quite often. Honolulu was still a sailor town in the late 50's and there were parts of Honolulu that were considered slums, so generally, we stayed away from Honolulu. The exception was to go see the golden statue of King Kamehameha. The huge statue of the legendary King Kamehameha was covered in gold leaf from head to toe and was beautiful. I was just as impressed by a very old Banyan tree next to Kamehameha. The trunk was already thick and prop roots, the roots which grow into the trunk, covered the the trunk, increasing it's size. It was a magnificent tree.
Honolulu also was home to the Iolani Palace, the palace of past Hawaiian Royalty. I didn't tour the palace although it was a possibility. Waikiki was considered a tourist beach, so we didn't go there either. Waikiki was not nearly as nice as the beaches on the leeward side of Oahu.
Hawaii is a contrast of beaches, mountains and valleys. There were sugar cane and pineapple fields, the pineapple fields seemed to go on and on forever. We would drive around the island viewing all of the sights. The Nuuanu Pali, a well known spot on the mountain where King Kamehameha defeated the Oahu natives by invading and forcing the enemy over the cliff, was the spot where my sister Linda staged a temper tantrum, refusing to exit the car when we stopped there. It is said that King Kamehameha himself went over the cliff, but the wind (which is quite strong at the Pali) blew him back up on the mountain.
It seemed like we saw a rainbow anytime we traveled around the island. It rained frequently and rainbows were the beautiful result. With rainbows, lush vegetation, mountains and beautiful beaches, Hawaii was indeed, a paradise.
