1. From Honolulu: Diamond Head Hike, Kailua Town & Kaneohe Bay
Explore the very best of Oahu in a single day. Start with an early-morning hike, then head to Kailua town for some shopping. End your day with fun water activities on a trip to the Kaneohe Bay Sandbar. Begin your day-long Oahu adventure with a convenient pickup in Honolulu and head to your first stop for the day, Diamond Head State Monument. Hike the Diamond Head Trail and marvel at expansive, 360-degree views of Waikiki, Honolulu, and the surrounding areas from the top of the crater. After your invigorating morning hike, it's time to head to the nearby town of Kailua. Located on the east coast of Oahu, this picturesque town offers a selection of incredible restaurants, boutique stores, and breweries. Make the most of your 3 hours of free time in this quaint town. Browse the local stores, check out the poke bar in whole foods, or head to the local chocolatier to sample different types of chocolate. End your day with a trip to Kaneohe Bay, one of Oahu's most idyllic areas. Hop onto a boat and head out to the Kaneohe Sandbar, a natural formation located at the center of the reef-protected bay. Spend 3 hours here, soaking up the sun and enjoying a range of water activities including a sandbar walk, snorkeling, kayaking, water volleyball, banana boat rides, and bumper tube rides. Take in the breathtaking scenery with panoramic views of the Koolau Mountains and nearby islets. Refuel with a light lunch served on the boat which includes a croissant sandwich, salad, fresh pineapple, and chips. End your day with a transfer back to Honolulu by air-conditioned bus.
