Oahu's coastal roads are flat, well-paved, and, unfortunately, awash in vehicular traffic. Frankly, biking is no fun in either Waikiki or Honolulu, but things are a bit better outside the city. Your best bet is to cycle early in the morning or get off the road to check out the island’s bike trails.

Best Spots

Kaena Point Trail. If going up a mountain is not your idea of mountain biking, then perhaps Kaena Point Trail is better suited to your needs. A longer ride (10 miles) but much flatter, this trail takes you oceanside around the westernmost point on the island. You pass sea arches and a mini-blowhole, then finish up with some motocross jumps right before you turn around. There's no drinking water available on this ride, but at least at the end you have the Yokohama Beach showers to cool you off. 69-385 Farrington Hwy., Waialua, Hawaii, 96791.

Maunawili Demonstration Trail. Locals favor biking this 10-mile trail that has breathtaking views as you descend into Waimanalo. There are many flat portions but also some uneven ground to negotiate unless you're willing to carry your bike for small stretches. The main trailhead is at the Pali Lookout on the blacktop of Old Pali Rd. Nuuanu Pali Dr., at Pali Lookout, Honolulu, Hawaii, 96817.

West Kaunala Trail. Biking the North Shore may sound like a great idea, but the two-lane road is narrow and traffic-heavy. We suggest you try the West Kaunala Trail. It's a little tricky at times, but with the rain-forest surroundings and beautiful ocean vistas you'll hardly notice your legs burning on the steep ascent at the end. It's about 5½ miles round-trip. Bring water because there's none on the trail unless it comes from the sky. 59-777 Pupukea Rd., at the end of Pupukea Rd., Haleiwa, Hawaii, 96712.

North Shore Bike Park. Wind around 12 miles of trails plus seven professionally designed, single-track loops at the North Shore's Turtle Bay Resort. Trails lead to protected wildlife areas and ancient Hawaiian sites, a WW II pillbox, a giant banyan tree, and secluded beaches and bays. Purchase day passes at the Hele Huli Adventure Center. 57-091 Kuilima Dr., Kahuku, Hawaii, 96731. 808/293–6024; Day pass $10.
