On the western most tip of the island, you can enjoy the views of not only ocean, but the wildlife that has been preserved thanks to the efforts of Hawaii State Parks. There is almost no shade here, so bring plenty of water and sunscreen as to not be super uncomfortable on the light plane flight back home!

The road ends here, but a trail continues on for quite a bit. Just off of the road (maybe 150 feet on the left) is a hole in the rocks that is shaped like a heart from the right angle.

Puʻu Hapapa Summit Trail is the challenging part of your hike to Puʻu Hapapa Summit. It includes many tough inclines, rock scrambling and drop-offs that are not for you if you are afraid of heights. But on the other hand, this trail also offers great views, especially once you reach the ridge.

While the Waianae Kai Forest Reserve offers a range of trails, there are a few routes that are particularly suitable for families. These include options like the moderate Sea arch at Kaʻena Point – Westernmost Point of Oʻahu loop from Mākua Beach, which provides a relatively flat coastal experience.
The terrain in Waianae Kai Forest Reserve is quite varied. You can find relatively flat coastal paths, such as those leading to Kaʻena Point, which follow old railroad beds. Other areas feature steeper volcanic ridges and forested valleys, offering a more rugged experience. Trails can range from dry, mesic forests at lower elevations to native wet forests higher up.
Yes, there are loop options available. The Sea arch at Kaʻena Point – Westernmost Point of Oʻahu loop from Mākua Beach is a moderate, longer loop that offers coastal scenery and is relatively flat, making it a good choice for families looking for a full-day adventure. For a more challenging loop, the North Shore viewpoint – Covered Shelter loop from Mokuleia provides significant elevation gain and panoramic views.
The reserve offers stunning natural features and panoramic views. From higher elevations, you can enjoy expansive coastal and Pacific Ocean vistas, including overlooks of Makaha Valley. The Kaʻena Point trail leads to Hawaii's westernmost tip, where you can see tide pools and the iconic sea arch. The Waianae Mountain Range itself provides a dramatic backdrop to many trails.
The Waianae Kai Forest Reserve is generally pleasant for hiking year-round due to Oahu's tropical climate. However, for family hikes, it's often best to go during the cooler, drier months, typically from April to October, to avoid heavier rainfall and humidity. Always check local weather forecasts before heading out, especially for trails that involve stream crossings or can become muddy.
Specific regulations regarding dogs can vary by trail and section within the reserve. It's always recommended to check the latest rules for each specific trail you plan to hike. Generally, if dogs are permitted, they should be kept on a leash to protect native wildlife and ensure the safety of all hikers.
The reserve is home to diverse ecosystems and is a critical habitat for native Hawaiian plants like 'O'hia and Koa. You might also spot endangered and endemic bird species such as the Oahu elepaio and the Hawaiian hawk. Along coastal trails like Kaʻena Point, you may see various marine life in tide pools.
Parking availability varies by trailhead. For popular access points, such as those for Kaʻena Point, there are often designated parking areas. However, it's advisable to arrive early, especially on weekends, as spaces can fill up quickly. Always ensure your vehicle is secured and do not leave valuables in plain sight.
Given the varied terrain and climate, it's best to wear comfortable, closed-toe shoes suitable for hiking. Bring plenty of water, snacks, sun protection (hat, sunscreen), and insect repellent. Depending on the trail, a light rain jacket might be useful. For longer hikes, consider a small first-aid kit and a map or GPS device.
