Oahu Island Vacation

The most populated island. On Oahu you will find the city of Honolulu, Waikiki Beach, Pearl Harbor, and the famous North Shore known for its big wave surfing. While the island is the most populated, most of the people are concentrated in the city of Honolulu on the south shore. But on this island, you'll find rainforests, deep canyons, valleys and waterfalls, a nearly mile-high mountain range, coral reefs, and gold-sand beaches. The city proper of Honolulu -- where most of Oahu's residents live -- is approximately 12 miles wide and 26 miles long, running east to west, roughly between Diamond Head and Pearl Harbor. Within the city are seven hills laced by seven streams that run to Mamala Bay.
