Summit a Volcano: Your Field Guide to Haleakalā National Park
Haleakalā, or the “House of the Sun,” is the colossal shield volcano that forms more than 75% of Maui. Visiting the summit is a must, but for the OutwardLab explorer, it’s more than a photo op. It’s a high-altitude mission that requires preparation.
The Classic Sunrise Mission
Watching the sunrise from 10,023 feet is an unforgettable experience, but it’s also one of the most common problems with things to do in maui if you’re unprepared. It is freezing at the summit before dawn, often dropping into the 30s or 40s Fahrenheit, with significant wind chill.
Pro-Tip: Reservations are required for sunrise entry (3 a.m. to 7 a.m.) and must be booked online in advance. They sell out fast, so plan ahead.
Your gear list should include:
- A warm insulated jacket (like a Patagonia Nano Puff or Arc’teryx Atom LT).
- A windproof/waterproof outer shell.
- A warm hat, gloves, and wool socks.
- Sturdy, closed-toe shoes.
- A headlamp (like a Petzl Actik Core) for navigating in the dark.
- A thermos with a hot drink.
Hiking Into the Crater
The real adventure begins after the sun is up. The crater floor feels like another planet, and hiking it is one of the most rewarding challenges on the island. The Keoneheʻeheʻe (Sliding Sands) Trail is the most popular route.
You can do an out-and-back day hike. A good goal for a strong hiker is the 3.9-mile trip to the Ka Luʻu o ka ʻŌʻō cinder cone and back (7.8 miles total). Remember, the return trip is all uphill at high altitude. Pace yourself, drink plenty of water, and know your limits. Altitude sickness is a real risk.
Stargazing and Backcountry Camping
If you have the gear and experience, skip the sunrise crowds entirely. The night sky from Haleakalā is one of the clearest on Earth. The park also offers two primitive wilderness campsites, Hōlua and Palikū, accessible via strenuous hiking trails. This requires a permit and full backcountry self-sufficiency.
Hike the Road to Hāna: A Backcountry Explorer’s Approach
The Road to Hāna is legendary, but for our community, the drive is just the access point. The real journey lies on the trails that branch off this winding coastal road. This is how to things to do in maui with an adventurer’s mindset.
Pīpīwai Trail & Waimoku Falls
Located in the Kīpahulu District of Haleakalā National Park (the coastal section past Hāna), the Pīpīwai Trail is a 4-mile round-trip stunner. It takes you through a dense, otherworldly bamboo forest and ends at the base of the towering 400-foot Waimoku Falls.
Safety First: This is a rainforest. Trails can be muddy and slippery. Wear hiking boots or trail runners with excellent grip, not sandals. Flash floods are a serious danger in the streams and pools; never enter the water if it’s raining or looks like it might rain upstream. Heed all posted warnings.
Waiʻānapanapa State Park
Famous for its black sand beach, sea caves, and freshwater pools, this park is another essential stop. A reservation is now required for all non-resident visitors. The best way to experience it is to hike the short coastal trail that runs along the dramatic, jagged lava coastline. It offers incredible views and a bit of solitude away from the main beach.
Sustainable Ocean Adventures: Eco-Friendly Snorkeling and Kayaking
Maui’s marine life is a treasure. As responsible outdoor enthusiasts, it’s our job to interact with it in a way that causes no harm. These are the eco-friendly things to do in maui that protect what we came to see.
Reef-Safe Practices
The coral reefs are fragile living ecosystems. Follow these things to do in maui best practices to protect them:
- Use mineral-based sunscreen only. Chemicals like oxybenzone and octinoxate are proven to kill coral. Look for sunscreens with zinc oxide or titanium dioxide.
- Never touch or stand on coral. It can kill the delicate polyps. Find sandy spots to stand if you need a break.
- Give wildlife space. It is illegal to touch or harass Hawaiian green sea turtles (honu) and Hawaiian monk seals. Keep a respectful distance of at least 10 feet.
Choosing Your Adventure
Instead of large, crowded tour boats, consider a guided kayak tour with a certified naturalist. These smaller groups have less environmental impact and offer a more educational experience. You’ll learn about the marine ecosystem and how to be a better steward of it. Honolua Bay and Olowalu are fantastic spots known for their vibrant reefs and turtle populations.
Maui Camping and Overlanding: Best Practices for a Night Under the Stars
For the truly self-reliant traveler, camping is the ultimate way to experience Maui. It requires more planning than a hotel stay, but the rewards—solitude, stunning scenery, and a deeper connection to the island—are immense.
Where to Camp
Permits are required for all public campgrounds. Book well in advance, as spots are limited and fill up quickly.
- Hosmer Grove (Haleakalā National Park): A simple campground near the summit entrance. It’s a great base for exploring the park and acclimatizing to the altitude. It’s nestled in a forest of non-native trees, offering a unique, high-elevation camping experience.
- Waiʻānapanapa State Park (Hāna): Camping here allows you to experience the black sand beach and coastal trails after the day-trippers have left. The sound of waves crashing on the lava rock is an incredible way to fall asleep.
- Polipoli Spring State Recreation Area (Upcountry): For the more rugged adventurer, Polipoli offers a cool, misty escape in a forest of cedar, pine, and cypress. It requires a 4×4 vehicle to access and offers a completely different environment from the coast.
The Maui Camping Care Guide
A good camper is an invisible one. Follow Leave No Trace principles rigorously. Pack out everything you pack in, including food scraps. Use designated fire pits only when and where fires are permitted. Be prepared for rain; a quality tent with a good rainfly, like the MSR Hubba Hubba, and a dry bag for your essentials are non-negotiable.
Frequently Asked Questions About Adventurous Things to Do in Maui
Do I need to rent a 4×4 vehicle in Maui?
For most of the adventures listed here, a standard rental car is sufficient. However, if you plan to explore more remote areas like Polipoli or the “backside” road from Hāna, a high-clearance 4×4 like a Jeep Wrangler is highly recommended. Some rental car agreements prohibit taking standard cars on these roads.
What are the biggest safety risks for hikers in Maui?
The two biggest risks are flash floods and dehydration. Never cross or swim in streams if it’s raining or the water is rising or murky. Always carry more water than you think you’ll need, especially on exposed trails like those in Haleakalā. A hydration reservoir like a CamelBak makes it easy to sip consistently.
How can I be a more respectful and sustainable visitor?
Beyond Leave No Trace, you can support local farmers’ markets, shop at local businesses, and learn a few Hawaiian words like aloha (hello/goodbye/love) and mahalo (thank you). Always respect private property and “no trespassing” signs. Understand that you are a guest on a sacred island with a rich cultural history.
This commitment to responsible travel is a core part of our sustainable things to do in maui philosophy. It ensures the island remains a place of wonder for everyone.
Your adventure in Maui is what you make it. By preparing properly, choosing your activities wisely, and moving with a sense of respect and stewardship, you can go far beyond the typical tourist experience. You can build skills, gain confidence, and create memories of an island that is powerful, beautiful, and profoundly wild.
Now, get out there and explore with purpose. Stay safe, and leave the island a little better than you found it.
