Diamond Head Crater hike

Price: $$

Diamond Head Crater, the photogenic volcanic landmark seen in many images of Waikiki Beach, isn’t just amazing to look at — it’s also incredible to climb. Active cruisers can take on the challenge during a guided Diamond Head adventure hike to its 763-foot summit. The payoff? Remarkable 360-degree views of Waikiki, downtown Honolulu and the Pacific Ocean.

This excursion requires you to ascend a series of moderate but sometimes uneven switchback trails followed by a walk through a narrow 200-foot tunnel. You’ll then climb up two sets of steep stairs (76 steps and 99 steps, respectively). Those taking the more difficult route to the summit will need to climb the 99 steps and an interior spiral staircase to reach the historic lookout bunkers. If you choose the easier route to the summit up the scenic Loop Trail, you’ll then descend into the bunker and down the spiral staircase and 99 steps. You can also retrace your steps and descend on the Loop Trail.

Important to know: If available, book an early morning tour, as temperatures escalate quickly by midmorning. Also, wear sneakers and a hat and bring sunscreen and water. The hike is about 1.6 miles round-trip and takes 60 to 90 minutes, depending on the group and the number of people on the trail. The total tour time is three to three and a half hours.

Oahu’s North Shore tour

Price: $$-$$$

If you’ve visited Honolulu before or simply prefer scenic locales to cities, a good option is a tour that whisks you away from the bustle of downtown Honolulu and Waikiki and through the Ko’oalu Mountains to the immersive beauty of Oahu’s North Shore. This lush and dramatic coastline is known for the big waves that pound its beaches from October to March and for its waterfalls, sugarcane fields and historic fish ponds. The region is visually stunning, and its small towns offer a chance to sample Hawaiian cuisine, especially garlic shrimp, and shop for locally grown products such as macadamia nuts and pineapples.

Highlights include big-wave surfers riding the famed Banzai Pipeline (during winter months); the Byodo Temple, a Buddhist shrine built amid towering green peaks in 1968 to commemorate the 100th anniversary of the first Japanese immigrants to Hawaii; the waterfalls of Waimea Valley; and historic Haleiwa Town.

Important to know: North Shore excursions are typically five to seven hours in length, with at least half the time spent on the tour bus. On sailings that end in Honolulu, some cruise lines offer panoramic North Shore tours combined with an airport drop-off (available for those with flights departing after 5 p.m.).

The Polynesian Cultural Center and Luau

Price: $$-$$$$

This 42-acre living museum in Laie on Oahu’s northern shore showcases Polynesian life past and present. Stroll through six authentically recreated villages — Hawaii, Fiji, Aotearoa (New Zealand), Samoa, Tahiti and Tonga. “Residents” of each village perform traditional dances and demonstrate daily life through music and various activities. Guests can even participate in hands-on experiences such as playing a Tongan drum, climbing a coconut tree, weaving a lei or throwing a spear.

Sample local dishes and buy authentic Hawaiian crafts at the 119,000-square-foot Hukilau Marketplace. Don’t miss the Ukulele Experience for a chance to see how rare koa wood is transformed into the iconic instrument.

Many cruise lines offer excursions here, or you can book one through a private tour company. Most excursions include tours through the six villages (guided, group or self-guided), an evening performance of “Ha: Breath of Life,” and an authentic luau or buffet dinner. Luau guests can savor traditionally prepared crispy garlic shrimp, Kalua pork, fresh-caught fish and other Polynesian dishes.

Your visit also supports the larger Pacific Island nations community. The center is partly staffed by local Brigham Young University students, many of whom hail from the Pacific Island nations they represent. It’s part of a sponsorship program that provides students with tuition, books, lodging and meals in exchange for part-time work at the center. Students also receive a paycheck to cover their incidental expenses.

Important to know: The duration of the tour ranges from around seven to 10 1/2 hours, depending on your package. You’ll begin and end the excursion with a 90-minute motorcoach drive through the lush landscape. Wear comfortable walking shoes.

Iolani Palace and Hawaiian Monarchs tour

Price: $$

If Hawaii’s royal history intrigues you, consider an excursion to Iolani Palace, the final residence of the islands’ kings and queens, and other sites of royal significance. Constructed in 1882, Iolani is the only royal palace in the United States. It was home to King Kalakaua, who built it, and his sister and successor, Queen Liliuokalani, who was imprisoned there after the U.S. annexed Hawaii. A circa-1883 statue of King Kamehameha I, who unified the Hawaiian Islands in 1810, and Kawaiahao Church, completed in 1842, are also nearby in downtown Honolulu.

Other royal sites you can visit on a more extensive tour include the Pali Lookout, where Kamehameha I conquered the island of Oahu in 1795, and Mauna Ala, the royal mausoleum where six of the last eight Hawaiian monarchs are entombed.

Important to know: Most Iolani Palace and royal-focused shore excursions last about four hours and combine a bus tour with a self-guided audio tour of the palace.

Kahului, Maui

Haleakala Crater

Price: $$$-$$$$

Experiencing Haleakala Crater is on many Maui visitors’ must-do lists, and there are several ways to visit the slumbering 10,023-foot-tall volcanic peak that dominates the island’s landscape. (Don’t worry — it last erupted in 1790.) A few shore excursion options require that your cruise ship overnights on the island or has a late sail-away time.

Haleakala means “House of the Sun” and perhaps the most surreal experiences are tours at sunrise or sunset. To experience sunrise high above the clouds, you’ll need to depart the ship before 3 a.m. and wind your way up Haleakala’s curving roadway in total darkness before watching the sun brighten the horizon and illuminate the vast 3,000-feet-deep crater with its dramatic orange-hued cinder cones. In contrast, a sunset tour lets you survey the crater and then watch as the sun disappears below the clouds and the night sky fills with twinkling stars. If you just want to experience Haleakala’s crater and scenic slopes in daylight, panoramic sightseeing tours are also available.

If you’re more adventurous, consider a Haleakala downhill biking tour, which transports you by minibus to an elevation of 6,500 feet and lets you ride 14 miles down the switchback road on Haleakala’s slopes amid the farms of Upcountry. Most bike tours do not offer access to the summit and crater.

Important to know: Haleakala tours typically last four to seven hours. Because of Haleakala’s high altitude and volcanic nature, tours aren’t recommended for anyone with respiratory or heart problems. Temperatures are much cooler (45 to 65 degrees) at the summit, so bring a sweater or jacket.

Road to Hana

Price: $$$-$$$$

Driving Maui’s legendary Road to Hana, a narrow, twisting, 52-mile route with more than 600 hairpin curves and 59 one-lane bridges, takes considerable concentration — but a Road to Hana tour on a professionally driven minibus frees everyone in your travel group to relax and enjoy the epic scenery along the way. Most cruise lines offer full-day excursions to Hana, a low-key hamlet located on the island’s east coast amid jagged volcanic rocks and black-sand beaches.

Besides the thrill of this iconic drive, which takes two to three hours to navigate, a Road to Hana excursion offers a chance to experience Maui’s splendid bays and lush landscape of lava pinnacles, tropical fruit trees, giant ferns and rushing waterfalls. Highlights include the black-sand beach at Wai’anapanapa State Park, Pua’a Ka’a State Park and the Seven Sacred Pools of Ohe’o Gulch with its multiple cascades and soothing natural pools.

Important to know: Road to Hana excursions typically take nine to 10 hours, include lunch and aren’t recommended for anyone prone to motion sickness. Sites visited vary by cruise line and some tours allow time for swimming.

Molokini Crater snorkel

Price: $$$

Maui is home to one of the premier snorkel spots in Hawaii: Molokini, a mostly submerged crescent-shaped volcanic islet located about 2.5 miles off Maui’s southern coast. You can reach this protected marine conservation site via a scenic catamaran sail, during which guides will outfit you with snorkel gear and provide instructions for exploring these crystal-clear reef waters teeming with colorful sea life. Some excursions also visit Turtle Arches, lava formations known for frequent sea turtle sightings. It’s also possible to spot whales in the area during humpback whale season (December to April).

Important to know: Molokini Crater snorkel tours are generally four hours long, and all equipment, breakfast, lunch, snacks and beverages are provided. Water conditions can vary, so if seasickness is a problem, take that into consideration before booking.

Whale watching

Price: $$

If you’re cruising Hawaii between December and April and you’re fascinated by whales, Maui offers a terrific opportunity to see pods of humpbacks in their winter playground. More than 10,000 of these charismatic giants migrate here annually to mate and give birth. Their activities — tail slaps, breaches and calves swimming alongside their mothers — are all on display as you venture out in a whale-watching boat or perhaps a more adventurous Zodiac. Naturalist guides lead most tours, and in some cases, a portion of the cost is earmarked for conservation through the Pacific Whale Foundation.

Important to know: Expect to spend about three hours at sea as guides search for whales. Also, sightings, while likely, aren’t always guaranteed. Water conditions can also vary, and seasickness is a possibility.

Nawiliwili, Kauai

Waimea Canyon tour

Price: $-$$

Nicknamed the “Grand Canyon of the Pacific,” Waimea Canyon is a 10-mile-long gorge known for the dramatic red and green hues of craggy cliffs that extend up to 3,000 feet below its rim. It’s within Waimea Canyon State Park, which now requires reservations for individual visits. Visitors can view this scenic treasure from the lookout points.

A shore excursion that allows for about 30 minutes of viewing and picture-taking is certainly the easiest way to see the canyon from a cruise ship. These tours include lots of scenic touring during the 90-minute drive each way between the cruise terminal and the canyon; many stop at the Spouting Horn blowhole or small towns in Kauai’s Koloa district.

However, there are caveats, namely that rainy conditions on Kauai, Hawaii’s wettest island, can fog the gorge and make for a disappointing outing. Kauai’s driest months are April to September.

Important to know: Most Waimea Canyon excursions take four to five hours. Some longer Best of Kauai excursions combine a visit to the canyon with a Wailua River cruise to the Fern Grotto.

Hollywood in Hawaii tour

Price: $$$

Fans of “Jurassic Park” probably know that much of the 1993 Steven Spielberg movie was filmed on Kauai. However, a number of other big-screen and TV classics were filmed there, too. Movie-set tours are popular excursions, especially for film buffs. These tours take place on minibuses or motor coaches outfitted with TV screens, so you can watch snippets of Hollywood movies where they were filmed and, in some places, get out and snap photos yourself.

Besides “Jurassic Park,” other movies and TV shows filmed on the island include “Tropic Thunder,” “Pirates of the Caribbean,” “Six Days and Seven Nights,” “Blue Hawaii,” “South Pacific,” “Donovan’s Reef,” “Gilligan’s Island,” “Fantasy Island” and “The Amazing Race.”

Important to know: Most movie-set excursions take about five to six hours and primarily involve scenic touring — so even if you haven’t seen the movies, it’s an entertaining and comfortable way to sightsee Kauai.

Wailua River cruise and Fern Grotto

Price: $$-$$$

Kauai is home to Hawaii’s only navigable river, the Wailua River, which offers access to one of its lushest hidden spots: the Fern Grotto. This excursion combines a relaxing cruise with insights into Hawaiian culture and entertainment in the form of Hawaiian song and dance. The tourist boats that navigate this peaceful river through Wailua River State Park are run by a local family, with members providing commentary.

Access to the Fern Grotto, a natural lava-rock cave covered with lush tropical vines, requires a 10-minute walk along a mostly flat, paved and shaded path. Upon arrival at the Fern Grotto, photo ops and additional entertainment await. Wailua River cruise tours also generally stop for picture-taking at Opaeka’a Falls, a 151-foot cascade that plunges into a secluded pool.

Important to know: Most Wailua River and Fern Grotto excursions are three to four hours long. Tours that combine those sights with a tour of Waimea Canyon last about seven hours and include lunch.

 Hilo, Hawaii

Hawaii Volcanoes National Park

Price: $-$$

Hawaii Volcanoes National Park is one of Hawaii’s most popular tourist attractions. While it’s accessible from both cruise ports on the island of Hawaii, it’s a quicker trip (about a 30- to 35-minute drive each way) from Hilo. Most cruise lines offer excursions, but almost all of them are just a basic introduction that only touches on what this 505-square-mile national park has to offer.

The main activity involves visiting several viewpoints and steam vents on the rim of Kilauea Crater with a guide who offers commentary on this active volcano’s history, geology and current status. It’s unlikely you’ll see molten lava, and most tours do not drive out along the famous Chain of Craters Road. Some tours, however, do include a walk through the 500-year-old Thurston Lava Tube.

Other longer and more costly excursions, lasting up to seven hours, combine a visit to the national park with a helicopter flight-seeing tour and/or stops at various waterfalls or gardens near Hilo.

Important to know: Standard Hawaii Volcanoes National Park tours are about four hours long and may also stop at the Mauna Loa Macadamia Nut Visitor Center for tastings and shopping. The walk to the rim of the Kilauea crater is mostly on gravel or dirt pathways, but some areas overlooking the crater have potential trip hazards. Also, because the crater emits volcanic gases, these tours aren’t advised for people with respiratory issues.

Hilo waterfalls and gardens

Price: $-$$

Hilo’s location on the island of Hawaii’s lush leeward side makes it a mecca for cascading waterfalls and verdant gardens. Cruise ship excursions that visit several falls or combine a visit to a single waterfall with a stop at a botanical garden, tropical zoo or orchid farm are popular.

The two major falls near Hilo are the 100-foot Rainbow Falls, which earned its name from the prismatic effect that takes place on sunny mornings, and the powerful Akaka Falls, which is reached via a walk through a tropical forest and tumbles a breathtaking 442 feet. Other tour stops could include Hilo’s Liliuokalani Gardens (the largest Japanese garden outside of Japan), the Nani Mau Gardens or the Pana’ewa Rainforest Gardens and Zoo.

Important to know: Waterfalls and gardens shore excursions vary in length from four to seven hours, and participants should expect to be on their feet for a good portion of the tour. Rainbow Falls is easily accessible from the parking lot. To see Akaka Falls, you must navigate quite a few steps and walk a half-mile circular path.

Volcano Winery

Price: $$-$$$

The island of Hawaii is home to Volcano Winery, the southernmost winery in the U.S. If sipping vino is a favorite pastime — and you have a curious palate — an excursion here could be a relaxing way to spend a few hours. Volcano Winery, which is family-owned and located at an elevation of 4,000 feet, specializes in tropical blends by mixing distinctive local fruits such as yellow guava and even tea and honey with grape varietals that include pinot noir and Cayuga to produce uniquely flavored wines. It also produces some 100% grape wines.

Important to know: Excursions to Volcano Winery are generally three hours long and include a tour of the winery and a tasting.
