Also known as Ka’ena Point State Park, Ka’ena means, “heat” in the Hawaiian language. And not without reason – this 5 mile round trip hike provides no relief from the sun, as there aren’t many trees around for shade. What it does provide is excellent coastal views. There’s also a bird (moli) sanctuary, and some Hawaiian monk seal spottings at the end of the trail, depending on the time of year you visit.
My sister and I (beginner hikers) completed the trail in 2 hours and 45 minutes, but this also included all the time we took for various photo ops. There are a few narrow and tricky bends on the trail but for the most part, the hike is pretty flat and definitely doable. Just be sure to bring sunscreen and lots of water!
