Top Outdoor Activities in Honolulu

Diamond Head State Monument

This crater of an extinct volcano got its name when Western explorers mistook calcite crystals they found there for diamonds. The historic trail to the 761-foot summit starts inside the crater and is an easy, but steep, 45-minute hike to the top. Stay on the trail, wear appropriate footgear and sunscreen, take along water and bring a flashlight to light your way through the tunnels. Those who reach the summit are rewarded by a spectacular 360-degree view of O'ahu. The tunnel gates close promptly at 6p. Admission: USD1 per person, USD5 per vehicle.

Atlantis Adventures

In addition to owning and operating the popular Navatek I and Atlantis Submarines, this company works in conjunction with several major Honolulu attractions to provide guests with deeply discounted tour packages. Visit Sea Life Park, splurge on a dinner cruise/show package, or take a ride in one of the submarines. Call or check the website for more details.

Koko Crater Botanical Garden

This 200-acre stretch of Koko Crater was set aside in 1958, with a long-term (as yet only partially realized) plan of turning it into a botanical garden. Eventually, it will be a landscape where endangered plants suitable to this desert-like region can survive and flourish. Even in the early stages of development, visitors can find collections of plumeria and other flowers. A two-mile loop trail leads through dryland plant collections from around the world. No visitor facilities (restrooms, drinking fountains, etc.) have yet been constructed. Entrance to the garden is free.

Dolphin Quest

Located inside the Kahala Mandarin Oriental Hotel, this dolphin habitat draws visitors from up and down the island of Oahu. Dolphin Quest offers a variety of programs and encounters for everyone from children to couples. Guests and visitors have the chance to learn about these extraordinary creatures through fun and educational programs. To learn more, visit their website.

Popular activities sell out weeks in advance; book early before you arrive in Hawaii to avoid disappointment. Ticekts, maps, itineraries, and directions are delivered free via either e-mail or U.S. mail, to your home or your hotel.

Bike Hawaii

Bike tours for people of all ages and experience levels are offered here. Beginners and families can enjoy a downhill ride and a two-mile hike to a private waterfall. For mountain bike enthusiasts, the five-hour tour of Ka'a'awa Valley is a wonderful way to see O'ahu from a different perspective. This tour runs Saturday and Sunday. All prices include transportation to and from the hotel and snacks; rubber boots are available.

Aqua Zone

Scuba diving in a hotel pool? But of course! This company entices potential new divers by offering an introductory class in a swimming pool at no charge. If you like it, try an ocean dive with an instructor. Aqua Zone's custom boat will take certified divers to two locations. The price includes transportation, all equipment and refreshments. Dive sites include sea caves, sunken ships, and even a World War II fighter plane! Diving enthusiasts should ask about brand new hotel packages. The company also books other aquatic activities including water skiing, jet skiing, para sailing, charter fishing, snorkeling, and even surfing. There is an additional location in the Outrigger Waikiki on the Beach Hotel.

Hawaiian Parasail Inc

For the ultimate thrill, try this popular adventure sport. Sail above the seas on a small parachute that's being towed by a speedboat. People who have gone say there's nothing like it. This company is Hawaii's oldest parasail operator, and one of its most respected. It's been running for 25 years. You couldn't pick a better company in which to place your trust and your life. If going solo seems a bit scary, take a tandem ride. Adrenaline junkies are encouraged to ask about the "Wet and Wild Rides." Call directly or ask an activity broker for more information.

Hawaii Children's Discovery Center

Children are encouraged to learn about a diverse range of subjects at this busy, colorful facility. It offers a number of fanciful interactive displays and learning toys. Every subject from physiology to sociology is explored. Tour the 'Global Village' or play a game of volleyball...with a robot! The 37,000 square foot space offers several hours of entertainment for kids and parents. The center has been open since late 1998. It's geared toward children aged 3-13.

Aloha Parasail

This company offers more than one kind of thrill. While it's true that parasailing is the focus, Jet Skis are also available for people who like to keep a little bit closer to the ground (or in this case, the water). Scuba diving is also offered. If you've wanted to try parasailing though, this is a good bet; the company has been around since 1983. Call for pricing on parasailing or scuba adventures. Note: A credit card is required to hold, but cash is the only form of payment accepted. This allows the company to offer deep discounts much of the time. Reservations are required. Free door-to-door van transportation from Waikiki hotels is included.
