The Round Top Lookout via Round Top Drive offers a unique touring cycling experience, transforming from urban Honolulu into a lush tropical rainforest as you ascend. You'll ride through natural tunnels formed by banyan trees and navigate about 12 hairpin turns, with continuous panoramic views of Honolulu, Diamond Head, and Pearl Harbor unfolding below, especially from the Tantalus Lookout.
This moderate 6.3-mile (10.2 km) route involves a significant 1105 feet (337 metres) of elevation gain, typically taking around 54 minutes. The starting point is conveniently located near Honolulu and Waikiki. Be aware that the paved road can be narrow in sections, and while traffic is generally light, drivers are usually respectful.
This route is a fantastic option for cyclists seeking a good workout with high scenic rewards, but it's not recommended for beginners due to the continuous climb and average 5.7% grade. Puu Ualakaa State Park, located about halfway up, provides a great stop with restrooms, water, and picnic shelters, making it an ideal spot to refuel and enjoy the views.
