Travel back to World War II-era Hawaii on this tour of Pearl Harbor, the USS Arizona Memorial, and the Punchbowl National Cemetery. Explore informative museum displays, climb aboard a US Navy launch ship, and drive through historic Honolulu with a knowledgeable guide.

Begin at the Pearl Harbor Visitor Center, where you can watch a documentary film about the attack on Pearl Harbor before climbing aboard a US Navy launch ship to ride to the USS Arizona Memorial. Built over the sunken wreckage of this massive battleship, the memorial is a tribute to the 1,177 crewmen killed during the tragic events on December 7, 1941. Inside, somber memorials offer touching opportunities to honor the deceased.

Back on land, continue by bus to Punchbowl National Cemetery to pay tribute the men and women who served in the United States Armed Forces. Enter the chapel and reflect on the names of 28,788 missing military personnel, etched on the marble slabs of the grand staircase.

Wrap up your day on a narrated tour of downtown Honolulu, where you can snap photos of an 18-foot (5.4-m) tall statue of King Kamehameha—the monarch who united the Kingdom of Hawaii—and pass by the Iolani Palace—the only royal palace now a part of the United States.

Dip beneath the waters of Hanauma Bay and find out why this sheltered cove is one of Oahu's most popular snorkeling destinations. Drift past colorful coral reef formations, wave to passing sea turtles, and follow schools of neon-bright tropical fish.

Start your afternoon with convenient pickup from your hotel, and then ride out to the sugary sands that frame Hanauma Bay, a crescent-shaped body of water protected from the ocean's pounding surf. Grab your gear, get tips from expert staff on fitting your goggles on right, and then dive in.

Swim through gentle waves and scan the ocean floor for any one of the 114 species of fish that call this aquatic paradise home. You might see the black stripes of reef triggerfish or the nimble movements of a bright yellow Forceps Fish. Lucky snorkelers might even spot the giant shell of a majestic sea turtle.

The warm water ensures you can snorkel comfortably for hours, but if you need a break, find a place to soak up the rays on the beach or cool off under the shade of a swaying palm tree. A small snack bar is also available for a quick bite to eat or a refreshing drink between swims.

From the summit of Diamond Head Crater, Hawaii's volcanic formations, endless ocean, and lush mountains all come into striking perspective. On this morning hike from Waikiki, see nature at its most awe-inspiring and learn about its geological and cultural context from your knowledgeable guide.

After easy pickup and transportation from Waikiki, arrive at Diamond Head Crater, Oahu's iconic tuff cone. Begin your ascent to the crater's 763-foot (233-m) summit with your trained nature guide. Along the way, learn enthralling information about volcanic creation, Hawaiian history, and the crater's military use.

As you work up a sweat over the course of this 45-minute hike, stop periodically at scenic rest stops to take expansive photos and catch your breath. Traverse the unpaved terrain before entering a narrow 200-foot tunnel. Once inside, climb up a spiral staircase to the summit.

Your work pays off and then some once you reach the crater's rim. Take in a dazzling panorama that includes Waikiki, the Pacific Ocean's sparkling blue waters, and the island's sprawling emerald mountains. Learn some final facts about native plants and birds on your descent; then unwind on the ride back to your hotel.

From the high skies above Oahu, see the island's stunning hidden valleys and waterfalls only accessible by air. Picturesque views of Pearl Harbor await you, including the USS Arizona Memorial and the battleship Missouri.

Take to the sky and head out over the island of Oahu to take in famous locations and hidden treasures. Your pilot narrates your flight with fun, interesting facts and local history, using aviation-grade noise-cancelling headsets. Your Eco-Star helicopter provides 180-degree views of all the sights.

You might spot surfers catching the breakers as you fly over Honolulu and the famous Waikiki Beach. Stunning views of the Diamond Head crater, Hawaii's most recognized landmark, are yours to appreciate before you continue along the rugged coast to the North Shore. The crescent-shaped Hanauma Bay and white-sand beaches of Waimanalo highlight the landscape.

Next, soar into the valleys of the Nu'uanu rainforest to the thundering Sacred Falls. On the return back to the heliport, have your camera ready to take aerial photos of the USS Arizona Memorial and the USS Missouri in Pearl Harbor.

Come face-to-face with sharks 3 miles (4.8 km) off the shore of Oahu. With a snorkel and mask, dive into the Pacific Ocean to view these incredible creatures of the deep in their natural environment from the comfort and safety of a custom-built cage.

After a safety briefing, depart from the Haleiwa Boat Harbor and head out to sea. Take in the North Shore vistas on this gentle ride in a custom-made boat with covered, cushioned seating. Once at the shark viewing area, the cage is placed in the water. It floats at the surface, and when you enter the water you can choose to float or dive a few feet down while still in the safety of the cage.

With visibility that can reach 150 feet (45 m) or more, you can see the sharks come up from the cobalt-blue depths of the ocean. Watch as sharks ranging from 5–15 feet (1.5–4.5 m) in length circle only inches away from the cage. Viewing the sharks in their natural environment is a true wonder. Expect to see Galapagos sharks, sandbar sharks, all with unique traits that your guide shares through informative narration. Other marine life can possibly be seen such as: Spinner Dolphins, Barracuda, Mackerel, Tuna, Flying Fish and Humpback Whales (January-March).

Oahu's very first zipline course, the 7 ziplines at Keana Farms offer adrenaline-pumping rides plus an up-close look at a working North Shore farm. Trek along elevated boardwalks through the trees, glimpse views of the ocean, and race a friend down dual lines over the tropical landscape below.

Venture to Oahu's North Shore, where native forest blankets the hillsides, pineapple plantations line red dirt roads, and nostalgic beach towns like Haleiwa give way to world-famous surf spots. Your tour starts with a 4-wheel-drive ride down a rugged dirt road to the beginning of the zipline course. Walk along an elevated wooden pathway through the trees and step into your harness, listening as your guide shares tips for picking up speed and getting the most out of your zipline experience.

All 7 lines of this course are dual lines, so you can leap from the platform and race to the end against a friend or just take in the spectacular surroundings together. As you glide over the canopy and the forest floor below, look out at fields of tropical fruit to the white sands and azure waters of the coast. Various rope challenges test your balance and take you out of your comfort zone, as you climb and rappel and cross rope bridges between platforms. Throughout this eco-adventure, your guide shares insight into the surrounding flora and fauna and tells stories about Hawaiian history and culture, rounding out this unforgettable outdoor experience on the North Shore.
