Hau'ula-Waipilopilo Loop Trail is a 3.4 mile lightly trafficked loop trail located near Hauula, Hawaii that features a river and is rated as difficult. The trail offers a number of activity options and is accessible year-round.
This trail is an extension from the State's Hau'ula Loop Trail. It connects Hau'ula and Waipilopilo ridges into a very manageable loop. The trail can be overgrown as Uluhe is prevalent in this area. Be prepared with long sleeves and pants. There are a number of steep sections and blow downs, as well as narrow spots that you will need to keep your focus on so that you don't accidentally step into a hole off the ridge. The views from the ridge are expansive - giving you views from as far as Kahuku to Laie to Kaa'awa. Some views of Kaipapau Gulch with high waterfalls (if it is raining). Great day to take a walk up towards the KSRT. The path goes past Hauula Loop up onto Hauula Ridge overlooking Kaipapau Gulch. It starts as a wooded area with Kukui, Paperbark and Eucalyptus trees. It then becomes Koa and once it opens up, it is speckled with Ohia with Uluhe underwood. The path is a constant uphill with amazing views all around. Once at the end the ridge turns and connects via a short saddle to Waipilopilo ridge. The section connecting to the top of Waipilopilo is steep but manageable.
