Maui is no stranger to epic hikes, but the Pipiwai Trail leading to Waimoku Falls might just be the crown jewel of them all. Nestled deep within the lush Kipahulu District of Haleakalā National Park, this four-mile round-trip journey offers an unforgettable immersion into Maui’s rainforest, complete with a towering bamboo forest, incredible banyan tree, and the jaw-dropping 400-foot Waimoku Falls.
Why Hike the Pipiwai Trail?

How to Get There
Located at the Kīpahulu entrance of Haleakalā National Park, the trailhead is approximately 2 hours and 30 minutes from Kahului. You can get there via the scenic and winding Hāna Highway or take the quieter, more remote Pi’ilani Highway (also known as the “backside” route) which will cut about a half hour off the Hana Hwy route. While the Pi’ilani route offers sweeping views and less traffic, it has experienced closures over the years due to weather and road conditions—so be sure to check current accessibility before you go. As of June 2025, it was reopened after a closure lasting over a year. Whichever route you choose, it’s best to start early to avoid crowds and make the most of daylight hours. See our Hana Hwy Guide HERE.
Pro Tip: Your park entrance fee also grants you access to the summit area of Haleakalā within 3 days—perfect for combining a sunrise summit with a rainforest hike. See our sunrise guide HERE.
What to Bring
- Sturdy hiking/water shoes: Trail conditions can be muddy and slippery.
- Sun protection: Expect hot and humid conditions in the beginning.
- Plenty of water and snacks
- Bug repellent: Mosquitoes love the lush environment.
- Rain gear: This is a rainforest, after all.
- Camera or smartphone: You’ll want to capture every moment.
Flora, Fauna, and Cultural Significance
This hike isn’t just about scenic beauty. The Pipiwai Trail traverses through a dynamic ecosystem that includes ferns, bamboo, guava, mango, java plumb, coffee, and culturally significant sites tied to early Hawaiian life. The presence of taro patches and ancient irrigation systems hints at the ingenuity of the island’s first inhabitants.
Safety Tips
- Stay on the trail: Venturing off can damage fragile ecosystems and lead to dangerous conditions.
- Respect posted signs, especially near waterfalls and stream crossings.
- DO NOT SWIM under Waimoku Falls due to falling rocks. Fatalities have occurred.
Combine with a Visit to “‘Ohe‘o Gulch” (Seven Sacred Pools)
Just across the road from the trailhead lies the famous ‘Ohe‘o Gulch, also known as the Seven Sacred Pools. Although swimming is restricted due to safety concerns, it’s still worth seeing from the trail above. This isn’t far from where you park by the visitor center.
