There is a small covered shelter here that is a great spot to take a break or escape an afternoon shower. From the hut you have a great view of the surrounding EWA Forest Reserve!

This Boy Scout Rest Hut, with a great view and picnic table inside, serves as the return point for many. So you decide whether you want to continue further along the trail until its end or return from here.

Lower Waimano Trail and Upper Waimano Trail run parallel to each other and meet again after the first section, so actually it's up to you, which trail you prefer. The biggest advantage of the Lower Waimano Trail is, that it's a little further away from the street, and you don't have to hike along a fence. If you're hiking the loop, it makes sense to use both trails in one direction each.

Yes, as many other trails on Oʻahu, Waimano Ridge Trail also includes plenty of nice views! But the undoubted highlights of this trail are the tunnels, that were previously used for irrigation. If you're claustrophobic or one of the tunnels is in bad condition, there is usually a path leading around the tunnels as well. As it is an out-and-back-trail, it is up to you whether you want to hike until the end of the trail or return earlier.

Wahiawā Hills Trail is a relatively easy and short trail in the Ewa Forest Reserve. But be aware that there are still a lot of ups and downs, so you will certainly get your exercise. The trail crosses the river multiple times, and you can take a dip in one of the pools along the trail in the middle of the wooded landscape.

This viewpoint along Mānana Ridge Trail includes a little bench to have a seat and soak in the views.

While at the beginning of your hike along Mānana Ridge Trail, you will be surrounded by trees, the upper section is mostly covered by low vegetation, and it actually feels like you're walking on the ridge. Enjoy the beautiful views in all directions while feeling like you're on top of the world. Some parts of the trail might be overgrown a little, but it's no problem to keep track.
