The Big Island's biking trails range from easy to moderate coastal rides to rugged backcountry wilderness treks that will challenge the most serious bikers. En route, bikers can soak up some of the island's storied scenic vistas and varied geography -- from tropical rain forest to rolling ranch country, from high country mountain meadows to dry lava deserts. It's dry, windy, and hot on leeward coastal trails and cool, wet, and muddy in upcountry windward areas. There are long distances between towns and few services available in the Kau, Puna, South Kona, and Kohala Coast areas, so bikers need to plan accordingly for weather, water, food, and lodging before setting out.
The nonprofit Big Island Mountain Bike Association (Box 6819, Hilo, 96720-8934. www.interpac.net/~mtbike) has tons of information on biking the Big Island. It provides maps and detailed descriptions of rides for all ability levels. For other suggested rides, see the Web site run by Alternative Hawaii (www.alternative-hawaii.com/activity/biecotrb.htm).
Mountain Bike magazine voted Kulani Trails, south of Hilo, the best ride in the state. To reach the trailhead from the intersection of Highways 11 and 19, take Highway 19 south about 4 mi, then turn right onto Stainback Highway and continue on 2 1/2 mi, then turn right at the Waiakea Arboretum. Park near the gate. This technically demanding ride, which passes majestic eucalyptus trees, is for advanced cyclists.
The Old Puna Trail (Trailhead: From Hwy. 130, about 3 mi south of Keaau town, take Kaloli Rd. to Beach Rd.) is a 10 1/2-mi ride through the subtropical jungle in Puna, one of the island's most isolated areas. You'll start out on a cinder road, which becomes a four-wheel-drive trail. If it's rained recently, you'll have to deal with some puddles -- the first few of which you'll gingerly avoid until you give in and go barreling through the rest of them for the sheer fun of it. This is a great ride for all abilities that takes about 90 minutes.
