Fly through the eucalyptus trees and over Maui's upcountry valleys on Skyline Eco-Adventures' ziplines, with ocean views from 4,000 feet elevation on the slopes of Haleakala.
Skyline Eco-Adventures operates what is widely regarded as one of the most scenic zipline courses in the United States, on the upper slopes of Haleakala volcano in Maui's upcountry region. The course sits at roughly 4,000 feet elevation in the Kula Forest Reserve, a landscape of fragrant eucalyptus groves, native ohia trees, and sweeping valley views that stretch from the West Maui Mountains to the Pacific Ocean. On clear mornings the panorama extends to the neighboring islands of Molokai, Lanai, and Kahoolawe.
The course consists of eight ziplines of varying lengths, with the longest runs exceeding 800 feet and reaching speeds of approximately 40 mph. Participants are clipped to a dual-trolley system with redundant mechanical braking, and guides communicate between platforms via radio to ensure safe spacing between riders. All harnesses, helmets, and gloves are provided; closed-toe shoes are mandatory and must be worn throughout. The ziplining portion lasts approximately two to three hours, with additional time for transport from the base in Kihei or Kahului.
Skyline Eco-Adventures holds certification from the Association for Challenge Course Technology (ACCT) and submits to annual third-party safety inspections. Guides complete an extensive in-house training programme and hold first-aid and CPR certifications. Rescue procedures include a manual retrieval system on every line and trained staff stationed at each platform. The operation pioneered Hawaii's commercial zipline industry and has run courses on Maui since 2002.
Participants must weigh between 60 lbs (27 kg) and 275 lbs (125 kg) and be at least seven years old. No prior experience is required, and the course suits older children, teenagers, and adults of most fitness levels. Walking between platforms over uneven forest terrain is required throughout the tour, and some platforms are elevated with open edges, so a moderate level of mobility and comfort with heights is expected.
The eucalyptus forest setting means temperatures run 10 to 15 degrees Fahrenheit cooler than at sea level, making lightweight layers advisable even in summer. Afternoon cloud cover is common on the Haleakala slopes.

Tips for visiting
- Wear long pants to prevent harness chafing on the longer, faster lines
- Pack lightweight layers — Upcountry Maui at 4,000 feet runs 10-15°F cooler than the coast
- Closed-toe shoes are mandatory; sandals and flip-flops will result in denied participation
- Book the first departure of the day to maximise clear inter-island views before afternoon cloud rolls in
- GoPro chest mounts are typically permitted; confirm with the operator before arrival as head mounts may be restricted
When to visit
Year-round, though mornings from May through September offer the clearest inter-island views. The upcountry cloud line typically builds by early afternoon, so the first departure of the day maximises panoramic visibility.
Accessibility
The zipline course requires walking between elevated platforms over uneven forest terrain and is not accessible for wheelchair users or those with significant lower-body mobility limitations. Participants with upper-limb limitations should consult the operator in advance, as gripping trolley handles during each line is required.
Frequently asked questions
What are the minimum age and weight requirements for the Skyline zipline course?
Participants must be at least seven years old and weigh between 60 lbs (27 kg) and 275 lbs (125 kg). Weight limits ensure proper braking performance on all lines across the course.
Is prior zipline or climbing experience required?
No experience is needed. Guides deliver a full safety and technique briefing at the start of the tour using a short practice line before the main course begins.
What is the weather like at the Kula Forest Reserve?
The reserve receives more rainfall and cloud cover than coastal Maui and is significantly cooler. A lightweight rain jacket is recommended. Tours operate in light rain; severe weather may cause brief delays.
How long is the complete zipline experience from arrival to finish?
The ziplining portion takes approximately two to three hours. Including transport from the coast, the full excursion typically runs four to five hours.
Are there medical conditions that would prevent participation?
Participants with recent shoulder, back, or knee injuries, those who are pregnant, and those with certain heart conditions are generally not permitted to join for safety reasons. A health questionnaire is completed at check-in.
