What to expect on Ala Wai Canal – Tantalus Lookout loop from Waikīkī

This route is a journey of two distinct halves. You'll start with a relaxed, flat ride along the Ala Wai Canal, enjoying tranquil views of the water and glimpses of Waikīkī life. But don't get too comfortable; the real challenge begins as you turn towards Tantalus. The Tantalus climb is a "thigh burner" with steep grades and winding turns, including numerous hairpins, as you ascend through a lush tropical rainforest. Your reward for this effort comes at various viewpoints, especially Pu'u Ualaka'a State Park, where you'll find sweeping panoramic vistas of Honolulu, Diamond Head, and Pearl Harbor. This ride is best suited for cyclists with very good fitness who appreciate a rigorous climb followed by stunning scenery.

Planning your visit

The initial section along the Ala Wai Canal is generally smooth and paved. However, as you climb Tantalus, be aware that while the road surface is mostly good, some sections can be narrow with no shoulder. You'll need to be attentive, especially with mild traffic. This route is often highlighted as Honolulu's most extreme bike ride, so prepare for a significant workout. Consider starting your ride in the late afternoon to catch a spectacular sunset from the Tantalus viewpoints.
