O'ahu's natural beauty, breathtaking coastal routes, and year-round fair weather make it attractive to explore by bike. However, on many roads, bicycle lanes are limited or nonexistent, and cyclists must contend with heavy traffic. You can rent bikes for some solo cruising, join local cycling clubs for their weekly rides, or hit the road with outfitters for tours that go beyond the well-traveled paths.
