Maui has two legal single track trail systems, a world-class volcanic descent, and terrain that suits everyone from first-time riders to seasoned enduro racers. If you're looking for the best mountain biking in Maui, the island delivers far more than most visitors expect. At Krank Cycles, we've been putting riders on the right bikes for these trails for years, and we're the closest rental shop to both Maui’s major trail systems on the island.
Here's what you need to know before your first ride.
What Makes Mountain Biking in Maui Worth the Trip
Maui is one of the few places in the world where you can mountain bike through a dense rainforest, descend from near 10,000 feet on volcanic terrain, and ride in some form regardless of what the weather is doing that day. The island has over 11 distinct climate zones and more than 300 micro-climates, which means conditions vary significantly across different trail areas.
The trail systems here span beginner flow trails all the way to technical expert-level single track with serious elevation change. You don't need to be an advanced rider to have a great day on a Maui mountain bike trail. But if you are an advanced rider, the island has rides that will push you.
Year-round riding is another real advantage. Unlike many mountain biking destinations that shut down seasonally, Maui keeps trails accessible through most of the year.
Discover the Best Mountain Biking in Maui: Some of Our Favorite Trails
Makawao Forest Reserve: Maui's Best All-Around Mountain Bike Destination
The Makawao Forest Reserve, specifically the Kahakapao Recreation Area, is the central hub for mountain biking on Maui. There are seven trails and three dedicated skill areas inside the reserve, and the terrain covers every ability level from young beginners to all-mountain enduro riders.
The forest itself is striking. The first stretch of trail passes through dense eucalyptus with a strong scent that hits the moment you enter, followed by Cook Pine groves where the wind moves through the trees in a way that feels nothing like what most people picture when they think of Hawaii.
All trails inside the reserve are marked with red arrows, and maps are posted at intersections throughout. The Kahakapao Recreation Area sits about 3.8 miles from the Krank Cycles Mountain Shop in Makawao, a 10-minute drive, or a 45-minute uphill ride if you want to earn the descent the hard way.

The Pineapple Express Downhill Flow Trail
Pineapple Express is the headline trail at Makawao Forest Reserve, and it earns that position. The two-mile downhill-only flow trail runs from the upper part of the reserve down to the lower exit, and it's designed to be rideable by essentially anyone on a bike.
The trail is packed with table tops, which are the wide, flat-topped jumps that beginners can roll straight across while more experienced riders launch off the lip and catch air. A 5-year-old can have a great run on Pineapple Express. An expert can send it. The trail is one-direction only, downhill traffic only, so there's no concern about oncoming riders.
It's two miles of consistent flow, and most riders want to lap it.

Skills Areas for Every Rider Level at Makawao Forest
The reserve has three skill areas positioned for riders at different stages of development.
Akahi Akahi is the beginner area, the first one you reach from the parking lot trailhead on the right. The Hawaiian name means inexperienced or first time. It has berms and a small teeter-totter designed to build foundational bike handling before riders move onto the trails.
Pauma sits directly across from Akahi Akahi and is built for intermediate riders. It contains two pump tracks and an uphill skills section. Pauma means to pump, and that's exactly what this area is for.
Akamai is the expert area, located past the beginner zone on the right. It has a wooden step-up jump as the centerpiece, along with additional jumps and berms for riders who want to work on air and precision. Akamai translates to expert or smart, and the features match the name.
The Haleakala Skyline Trail: Maui's Most Epic Mountain Bike Descent
The Haleakala Skyline Trail is a different kind of ride entirely. It starts 1.25 miles southwest of the 10,023-foot Haleakala summit and runs 6.8 miles with 2,600 feet of elevation change. When combined into a full point-to-point ride from the summit to Rice Park in Kula, the total descent reaches nearly 7,000 vertical feet over 17 miles.
Plan for 2 to 3 hours on the trail and around 5 hours door to door from the Krank Cycles Mountain Shop.
The terrain above the treeline is mostly volcanic rock dotted with small shrubs. It's a moderately difficult rating, though the views from that altitude looking down over Maui's north and south shores and the valley below make this a ride you won't forget.
The trail connects to several additional routes. The Mamane Trail is a 1.8-mile connector accessible from the Skyline trailhead, good for most skill levels, and passes through mamane trees and sub-alpine shrubs with 520 feet of elevation change. From Mamane, you can connect to the Upper Waiohuli Trail, a 7-mile difficult route with 1,200 feet of change through rugged terrain and mixed pines, and from there to the Waiakoa Loop Trail, a 3-mile moderate loop through pine forest with excellent views in all directions.
Note: there are no shuttles or guided tours on the Skyline Trail. The trail crosses native Hawaiian lands, and the State of Hawaii has designated it free from commercial activity. Riders need to arrange their own vehicle logistics.
Poli Poli and the Maname Trails: Mountain Biking in All Weather
Poli Poli State Park and the Maname trail network offer a different riding experience from Makawao Forest, and there's one key practical advantage: you can ride Poli Poli in the rain.
Makawao Forest is a rainforest, and after heavy rain it needs a couple of days to dry out before conditions are good again. Poli Poli doesn't have that limitation. If you arrive on Maui and the forecast is wet, Poli Poli is where you go. The trails there ride in all conditions.
The park is the base of the Maui Skyline Trail and includes the Mamane Trail, Waikoa loops, and the Redwood Trail, giving riders a range of options within the same area.
