1. Beach Day and Surf Watching on the North Shore of Oahu

Soak It In, Don’t Dive In

Everyone hears about surfing the North Shore, but here’s the deal—unless you’re a total pro, this isn’t the place to paddle out in winter. The waves here are world-famous for a reason. Instead, grab a shaved ice, plant yourself on the sand, and watch the magic happen at Pipeline or Waimea Bay. It’s like watching a live extreme sports event, and it’s awesome.  You’re right up close to the action.

When to Go

Winter (November to February) brings the biggest waves and big-name competitions. Summer’s calmer if you want to try it, but even then, always check the surf report and be cautious.  Waikiki is always there if you want to get started safely.

2. Snorkeling at Molokini Crater, Maui

Crater Full of Color

Molokini is this half-moon-shaped crater off Maui’s coast, and the water here? Crystal clear. It’s a favorite for snorkeling because of the visibility and all the tropical fish. You’ll also most likely catch a sea turtle cruising by. Early morning tours are the way to go—less wind, fewer people, and calmer conditions.

Local Tip

Bring reef-safe sunscreen (always), and if you’re prone to seasickness, pop some meds beforehand. Those boat rides can get choppy.  Nothing worse than that seasick feeling.  The best way to stop it is to not get it.

3. Hiking the Kalalau Trail, Kauai

Bucket-List Worthy

This one’s for the hikers who like a challenge and aren’t afraid to get muddy. The Kalalau Trail takes you along Kauai’s Nā Pali Coast, with views that feel like they were taken on a movie set. It’s not easy—think slippery ridges, stream crossings, and major elevation—but it’s hands-down one of the most stunning hikes in the state.  I’ve done this hike and it’s definitely one of the better hikes I’ve ever been on.

What to Know

You need a permit even for day hiking past Hanakāpīʻai. Unless, of course, you’re a Hawaii native.  You get in free, no reservation necessary with a Hawaii State ID.  Check the weather beforehand—this trail isn’t safe when it’s raining. And bring more snacks and water than you think you need. Trust me.  You’ll need it.  Also, I love diving in the ocean afterwards.

4. Ziplining in Kauai’s Rainforests

Fast, Fun, and Full of Views

If you’re looking for a combo of adrenaline and jaw-dropping scenery, ziplining through Kauai’s rainforests is it. You’ll fly over lush valleys, jungle canopies, and sometimes even waterfalls, depending on the course. It’s the kind of thing that gets your heart pumping and your camera roll full in no time.

Good Options

Koloa Zipline is a favorite—they let you fly Superman-style on some of the longest lines on the island. Just wear closed-toe shoes and don’t forget bug spray. It’s the jungle, after all.

5. Volcano Tours on the Big Island

Where the Earth Breathes Fire

There’s nothing quite like standing near an active volcano to remind you how alive these islands really are. It doesn’t get more basic than liquified rock.  Hawaii Volcanoes National Park is where you’ll find Kilauea, one of the world’s most active volcanoes. You can walk across ancient lava fields, peek into craters, and if Pele’s feeling generous, even catch a lava glow at night.

Can’t Miss

The Kīlauea Iki Trail is a cool mix of rainforest and crater floor, and the Thurston Lava Tube is a quick, otherworldly detour. If lava’s flowing, book a night tour with a licensed guide—it’s unforgettable.  You can also park and walk in yourself without a guide.  Make sure everyone has a flashlight, or better yet a headlamp.  It’s D A R K.

6. Paddleboarding in Waikiki

Chill Vibes with Iconic Views

Waikiki might be busy, but it’s a great place to try stand-up paddleboarding, especially if you’re new to it. The waves are super mellow in the mornings, and you’ve got Diamond Head watching over you while you cruise. It’s peaceful, easy to learn, and you’ll probably spot a sea turtle or two if you’re lucky.

Insider Tip

Head out early—before the tradewinds pick up and the beach crowds roll in. Most of the rental spots will hook you up with a quick lesson and a waterproof phone pouch if you ask.

10. Kauai Helicopter Tours

See the Unreachable

Kauai is wild, green, and rugged—so much of it you can’t even get to by foot. That’s where a helicopter ride comes in. You’ll fly over the Nā Pali Coast, hover next to hidden waterfalls, and peek into Waialeale Crater (one of the rainiest places on Earth). It’s the only way to really grasp how untouched some of this island still is.

What to Expect

Flights usually last about an hour. Doors-on is great for comfort, but if you want amazing photos and don’t mind the wind in your face, go doors-off. Just book early—these tours fill up fast.

11. Hiking in Waimea Canyon, Kauai

The Grand Canyon of the Pacific

Waimea Canyon looks like Arizona met Jurassic Park. Red cliffs, green valleys, and deep gorges stretch as far as the eye can see. There are quick viewpoints if you’re short on time, but I always recommend putting on your hiking shoes and hitting the trails. You’ll see way more that way—and probably dodge the tour bus crowds.

Favorite Trails

The Canyon Trail to Waipo’o Falls is my go-to. It’s a manageable few hours round-trip with a killer view at the end. Just don’t forget water it gets hot.

12. Camping in Polihale State Park, Kauai

Off the Grid, On Another Level

If you’re craving solitude and starlit skies, Polihale is your spot. It’s way out on Kauai’s west side, backed by dunes and cliffs with a beach that stretches for miles. There’s zero light pollution, so the night sky is ridiculous. Think Milky Way kind of nights.

Need-to-Know

The access road is rough—like, pothole-on-pothole rough. A 4WD vehicle is highly recommended. And since there’s nothing nearby, pack in all your supplies, especially water. You’ll feel like you’re on a deserted island—in the best way.

13. Mountain Biking on Maui’s Haleakalā

From Summit to Sea

Imagine watching the sunrise from the top of a volcano, then coasting down 10,000 feet of winding road with sweeping island views the whole way. That’s mountain biking Haleakalā. It’s not technical—it’s paved the entire way—but it’s fast, scenic, and totally epic. You’ll pass through pine forests, pastures, and cute little towns as you go.

Pro Tip

Most outfitters provide bikes, helmets, and support vans. Go with a sunrise tour if you can—ok, it’s early, but worth it for the golden glow and bragging rights. Bring a windbreaker; it’s chilly at the summit even in summer.

14. Cliff Jumping at South Point, Big Island

Adrenaline Meets Ocean

South Point is the southernmost spot in the U.S., and it also happens to be a popular cliff jumping location. The cliffs here are about 40 feet high, with a ladder bolted to the rocks to help you climb back up. Locals have been jumping here for decades—but this one’s not for the faint of heart.

Safety First

Only jump if the water is calm and you’ve scoped out the landing. Currents can get strong, and the wind is no joke. If you’re unsure, skip the leap and just enjoy the view—it’s still wild and beautiful from the edge.  Don’t push past your comfort level here.

FAQs

1. What’s the best time of year to enjoy outdoor activities in Hawaii?

Honestly, Hawaii’s good year-round, but it depends on what you’re into. Winter (Dec–Mar) is perfect for whale watching and big wave surf-watching. Summer (Jun–Aug) has calmer ocean conditions—great for snorkeling, kayaking, and beach days. Spring and fall are solid for lighter crowds and cooler hikes.

2. Are these outdoor activities beginner-friendly?

Totally! There’s a mix for all comfort levels. Paddleboarding in Waikiki or a scenic hike in Waimea Canyon? Easy. Cliff jumping at South Point or hiking the Kalalau Trail? More intense. Just read up ahead of time and don’t be shy about asking your guides questions.

3. Do I need permits or reservations for any of these adventures?

Yup, for a few. Kalalau Trail needs a permit even for day hikes past Hanakāpīʻai. Camping at Polihale? Same deal. And for stuff like helicopter tours or manta ray snorkeling—book early, especially during peak seasons. Hawaii doesn’t do “last-minute” very well when it comes to popular tours.

4. Which island has the best variety of outdoor things to do?

They all bring something unique to the table. Big Island has volcanoes and manta rays, Kauai has dramatic hikes and remote beaches, Maui’s great for water stuff and bike rides, and Oahu has a little bit of everything. If you can, hop around—you won’t regret it.

5. Is it safe to do these activities on your own, or should I go with a tour?

Depends on the activity and your comfort level. Things like paddleboarding or snorkeling are super doable solo if you’re confident. For trickier stuff—like lava viewing, night snorkeling, or helicopter tours—go with the pros. Local guides know the land, respect the culture, and keep you safe.
