Take a look at life underwater with this 1-hour glass-bottom boat tour that showcases the hidden treasures of Oahu's blue waters. Watch for dolphins and whales above the surface, and visit one of the four glass-bottom viewing stations to check out colorful marine life below. Whether you spot coral reefs, old sunken ship hulls, or schools of tropical fish, this tour of Waikiki coast will highlight the best of this beautiful destination.

Enjoy two Hawaiian underwater adventures for the price of one with this 4-hour combination dolphin-swimming encounter and snorkeling trip. Start by exploring the 600+ species of marine life like sea turtles, coral and tropical fish that call the reefs of Kealakekua Bay home. Then meet up with a local pod of wild spinner dolphins for an optional swimming session. A trip choice without the dolphin swimming portion is also available.

Hawaii Volcanoes National Park is famous for its ever-flowing lava and the planet’s most massive active volcano. This tour journeys to top natural landmarks in and around the park. Visit Rainbow Falls, Richardson black sand beach, Historic Banyan Drive, Liliuokalani Gardens, Mauna Loa Macadamia Nut Factory, Akatsuka Orchid Nursery, and the active volcano of Kilauea. You also get the opportunity to walk through a lava tube.

Watching the sunrise at Haleakala Crater is a note-to-be-missed experience, which is only made better by hopping on a bike and riding back down to the beach. Begin early with a pre-dawn pickup before making the winding journey in the dark to the 10,023 ft. summit. As the horizon begins to slowly turn red, then gradually to orange and yellow, the lunar beauty of Haleakala Crater begins to come into view. After the sun has crested the eastern horizon and bathed the crater in light, ride back down to the national park boundray.

There are few places in all of Hawaii more historic than Kealakekua Bay, as it's the spot where Captain Cook was killed in a skirmish with native Hawaiians, and the Hawaiian monarch, King Kamehameha III was born just a few miles away. The history aside, it's also one of the best places to snorkel on the Big Island of Hawaii, and you'll have the chance to experience the beauty on this snorkeling tour from Kona. Search for dolphins on the way to the bay while admiring the volcanic coast, and after scouring the red for coral and fish, climb aboard for a lunch that's served by the friendly crew.
