From short waterfalls that cascade into small pools where you can swim to towering cascades you can only witness via helicopter tour, the waterfalls you’ll find in Hawaii are truly remarkable. And while you’ll find several Hawaii waterfalls hiding in plain sight — no hiking required — there are even more that are found off-the-beaten-path and only accessible via dirt paths. Today, we’re featuring a short and sweet hike that leads to a stunning waterfall swimming hole deep in the heart of Oahu.

Because this incredible destination is stream-fed, it is important to issue a friendly warning about the risks associated with flash flooding, and leptospirosis bacteria found in many of Hawaii’s natural pools. It is advised that you check weather reports and ocean conditions before heading out for the day, never swim in these pools when you have open wounds, and to always watch your step. With that warning out of the way, let’s lace up our hiking boots and make a splash.

Just a few minutes away from downtown Honolulu is one of the quickest waterfall hikes you’ll find on the island. Nestled just off the Pali Highway and along the Nuuanu Stream, Alapena and Kapena Falls will bring out your inner explorer with minimal effort.

Measuring in at less than a mile round trip, the trail begins near the Nuuanu Memorial Park and Mortuary and meanders through a thick forest.

And while this path will make you feel worlds away from civilization, the first cascade, Alapena Pool, will come into view on your right after just a few minutes of hiking.

Seriously, don’t blink or else you’ll miss it. Make your way down the short hill, and you’ll be rewarded with a small yet pleasant waterfall and swimming hole.
From here, follow the short path beyond Alapena Falls to reach Kapena Falls. Leading down to the pool’s edge, you’ll enjoy a phenomenal view of the 20-foot cascade and the large pool.
