Hawaii’s best experiences span six visitable islands, and we’ve ranked the 25 that earn their spot for 2026. We’ve sorted them by island and budget so you can build an itinerary without wasting a single beach day. Here’s exactly what to book and what to skip.
Key Takeaways
- Hawaii welcomed roughly 9.7 million visitors in 2024, with Oahu taking the largest share (Hawaii Tourism Authority, 2025).
- Hawaii Volcanoes National Park entry costs $30 per vehicle for a 7-day pass (National Park Service, 2026).
- Average summer hotel rates run about $390 per night statewide, so booking 3-4 months ahead saves real money (Hawaii Tourism Authority, 2025).
- Hanauma Bay caps daily snorkelers and sees crowds form before its 6:45 a.m. opening (City and County of Honolulu, 2026).
What Are the Best Things to Do in Hawaii?
The best things to do in Hawaii mix volcanic landscapes, world-class snorkeling, and scenic drives. We rank Hawaii Volcanoes National Park, Maui’s Road to Hana, Oahu’s Pearl Harbor, and Kauai’s Na Pali Coast as the four can’t-miss anchors. Everything else builds around those four.
You’ll want a rental car on every island except maybe Waikiki. Compare rates early on Discover Cars because inventory tightens fast in summer and prices jump 30-40% at the counter. We’ve seen compact cars hit $75 a day in July.
Best Things to Do on Oahu
Oahu packs the most variety, and it’s where most visitors land first. We’d start with Pearl Harbor’s USS Arizona Memorial (free, but timed tickets go in seconds), then hike Diamond Head for that classic crater-rim view. The Diamond Head reservation costs $5 per person plus $10 parking in 2026.
Don’t skip the North Shore. In winter, Banzai Pipeline produces surf that pros fly in for, and in summer those same beaches turn glassy and swimmable.
Top Oahu Picks
| Activity | 2026 Cost | Time Needed |
|---|---|---|
| USS Arizona Memorial | Free (reserve $1 fee) | 2-3 hrs |
| Diamond Head hike | $5 + $10 parking | 1.5 hrs |
| Hanauma Bay snorkel | $25 entry | 3 hrs |
| Polynesian Cultural Center | $89.95 adult | Full day |
Best Snorkeling and Diving Spots
Hawaii’s reefs rank among the clearest in the US, and you don’t need to be certified to enjoy them. Hanauma Bay on Oahu stays the easiest entry-level snorkel, while Molokini Crater off Maui delivers 100-foot visibility on calm mornings. Both reward an early start.
For Molokini, book a morning catamaran trip through Viator; afternoon winds chop up visibility. Half-day tours run $120-160 in 2026, gear included. Bring reef-safe sunscreen — Hawaii banned oxybenzone formulas back in 2021, and rangers do check.
Best Things to Do on Maui
Maui balances luxury resorts with raw nature, and the Road to Hana defines it. This 64-mile coastal drive crosses 59 bridges and passes dozens of waterfalls. We tell first-timers to either start at dawn or book a guided van so someone else handles the hairpin turns.
Haleakala National Park is the other Maui anchor. Sunrise from its 10,023-foot summit requires a $1 reservation plus the $30 park fee, and you’ll want a jacket — summit temps drop near freezing. Reserve your sunrise slot 60 days out through the park system because they vanish instantly.
Best Things to Do on the Big Island
The Big Island is where you watch the planet build itself. Hawaii Volcanoes National Park protects Kilauea, one of the world’s most active volcanoes, and 2024-2026 eruption phases have drawn record crowds. Entry is $30 per vehicle for seven days, and the Crater Rim Drive alone justifies the trip.
Beyond lava, the Big Island offers manta ray night snorkels off Kona — one of only a few places on Earth you can reliably do this. Book through GetYourGuide; trips run $130-170 and sell out in peak season. Mauna Kea stargazing rounds out the list, with some of the clearest night skies anywhere.
Big Island Cost Breakdown
| Experience | 2026 Price | Best Time |
|---|---|---|
| Volcanoes National Park | $30/vehicle (7-day) | Year-round |
| Manta ray night snorkel | $130-170 | Evening |
| Mauna Kea summit tour | $220-260 | Sunset/night |
| Akaka Falls State Park | $5 + $10 parking | Morning |

Best Things to Do on Kauai
Kauai stays the greenest and least developed island, and its Na Pali Coast is the headline. You can’t drive it — those 4,000-foot cliffs are only reachable by boat, helicopter, or the punishing Kalalau Trail. We think a catamaran tour gives the best value, running $160-200 through Viator.
Waimea Canyon, the “Grand Canyon of the Pacific,” is the other must-do, and it’s free to view from the lookouts. Pair it with a Wailua River kayak trip to the Fern Grotto for an easy half-day. Kauai rewards travelers who slow down rather than island-hop.
Best Free Things to Do in Hawaii
Hawaii’s biggest draws cost nothing. Most beaches are public by law, sunsets at Waikiki are free, and the lookouts over Waimea Canyon and the Na Pali Coast don’t charge admission. We’ve built entire trip days around zero-cost activities and never felt shortchanged.
Free standouts include the Lanikai Pillbox hike on Oahu, the Kona coffee farm self-tours (tastings free, beans extra), and the Kalalau lookout on Kauai. Pack water and reef-safe sunscreen and you’re set. Save your budget for the boat tours that genuinely require one.
Best Time to Visit and How to Get Around
Hawaii works year-round, but shoulder months — April-May and September-October — bring lower rates and thinner crowds. Summer and the December holidays push hotel rates toward that $390 nightly average, so we book those windows 3-4 months ahead through Booking.com to lock pricing.
Inter-island flights on Hawaiian and Southwest run 30-45 minutes and cost $50-90 one-way if booked early. You’ll still want a car on each island — public transit is thin outside Honolulu. Reserve through Discover Cars before you fly, not at the airport counter.
Frequently Asked Questions
How many days do you need in Hawaii?
We recommend 7-10 days for one or two islands. Five days barely covers Oahu alone once you factor in jet lag and travel time. If you want Maui plus the Big Island, plan 10 days minimum so you’re not rushing the Road to Hana or Volcanoes National Park.
Which Hawaiian island is best for first-timers?
Oahu suits most first-timers because it combines Waikiki’s easy logistics, Pearl Harbor’s history, and North Shore beaches in one compact island. Maui is the runner-up for couples wanting resorts plus nature. We’d save Kauai and the Big Island for return trips.
How much does a Hawaii trip cost in 2026?
Budget roughly $300-450 per person per day including the $390 average hotel rate, meals, a rental car, and one paid activity. A 7-day trip for two lands around $5,000-7,000 excluding flights. Booking lodging and cars 3-4 months ahead trims that meaningfully.
Do you need a car in Hawaii?
Yes on every island except a Waikiki-only Oahu stay. Attractions sit far apart, and transit is sparse outside Honolulu. Reserve a car before you arrive — counter rates spike 30-40% in summer, and inventory can sell out entirely on smaller islands like Kauai.
Can you see lava in Hawaii right now?
It depends on Kilauea’s current activity, which fluctuates. Hawaii Volcanoes National Park stays open year-round, and recent 2024-2026 eruption phases have produced visible glow at night. Check the National Park Service alerts before you go, since active flows shift and viewing areas change.
Is Hawaii expensive compared to other US destinations?
Yes, Hawaii ranks among the priciest US destinations, driven by shipped-in goods and high lodging demand. The $390 average summer hotel rate runs well above mainland norms. You can cut costs with condo rentals, free beach days, and shoulder-season travel in spring or fall.
What’s the best way to book Hawaii tours?
Book major tours — Molokini, Na Pali, manta rays — online before arrival through platforms like GetYourGuide or Viator, since peak-season slots sell out days ahead. Free hikes and beaches need no booking. Reserve timed-entry attractions like Diamond Head and Haleakala sunrise the moment windows open.
Plan Your Hawaii Trip
Hawaii rewards travelers who book the big stuff early and leave room for free beach days in between. Lock your islands, reserve your car, and grab the timed-entry slots first — everything else falls into place.
