Many travelers to Hawaii understandably head straight for the beach, but the ocean is far from the only place for a swim. Stunning waterfalls and tranquil pools abound across the islands’ lush landscapes. And when you’re done, let the balmy trade winds dry you off.
Here are some of our favorite places for a freshwater swim in Hawaii. Make sure to bring plenty of sunscreen, follow local safety regulations and don’t swim if you have open cuts, since some waterways in Hawaii can harbor bacteria like leptospirosis — and hazards are not always marked.
Oahu
Waimea Falls
This waterfall-fed pool on the North Shore of Oahu is one of Hawaii’s most popular swimming spots, and for good reason. A roughly 40-foot torrent tumbles into a deep basin that even visitors with strollers can easily reach. A three-quarter-mile paved path gently climbs through a botanical garden into the scenic Waimea Valley. Admission, including swimming, costs $26 for adults and $18 for children ages 4 to 12.
Waimea Falls takes safety seriously: Lifeguards are on duty, and life jackets, provided at no charge, are required. Water shoes are recommended, too, since the rocks can be sharp.
Swimming may not be allowed if the waterfall is too strong or if it dries up completely. Lifeguards assess the conditions each morning; prospective visitors can call 808-638-7766 for updates.
Kauai
Kahili Beach Preserve
Along the tranquil northern shore of Kauai, numerous waterways flow out of some of the wettest areas on earth. One, Kilauea Stream, forms a clear freshwater lagoon at Kahili Beach Preserve before flowing into the Pacific. The stream’s gentle flow, protected from the ocean surf by the curving edge of the beach, offers an inviting place to splash around with a clear view of the crashing waves.
The river’s lagoon is sheltered, but the waves on the other side of the sand can be rough and there are no lifeguards on duty. Ocean swimming is not advised.
The beach is accessible via a short dirt road with a small parking lot. If the lot is full, many visitors park on the roadside. Consider also visiting the meticulously landscaped Na Aina Kai Botanical Gardens next door (generally from $25 per person, reservations required).
Maui
Twin Falls
Travelers on the scenic Hana Highway, which winds along the northeastern coast of Maui, might want to start or end the 64-mile drive with a dip in Twin Falls, which features lower and upper waterfalls that each empty into a pool. The lower falls are easily accessible from the parking lot, while the upper falls require a nearly two-mile round-trip hike that can get muddy after it rains. Bring sturdy shoes.
Twin Falls is privately owned and part of Wailele Farm, which grows a variety of fruits and plants used in traditional medicine. A stand near the entrance sells homemade snacks and juices.
Parking costs $10 and is limited, so plan to visit either early in the morning or late in the afternoon for your best chance at getting a spot. Note that Uber and Lyft aren’t allowed to drop off at the park. On the first Saturday of each month, the falls are open only to Hawaii residents.
You can reach this swimming hole northeast of Honolulu via the Judd Trail, a mile-long loop over mossy stones and through dense, untamed forest. The waterfall at Ginger Pond is small — it’s more of a cascade over some rocks — but the pool is deep enough for a rope swing that keeps locals and tourists alike entertained.
For more adventurous hikers, the Nu’uanu Trail branches upward from the loop path, and switchbacks eventually climb to a viewpoint with dramatic views of Honolulu and its mountainous environs. There’s parking available on the roadside next to the trailhead, but the area has experienced car break-ins so be sure not to leave any valuables inside.
Big Island
Kulaniapia Falls
While some of Hawaii’s most scenic swimming spots can get busy during peak periods, this towering waterfall on the outskirts of Hilo, on the Big Island, offers a more private experience — if you’re willing to pay.
Kulaniapia Falls is owned by the aptly named Inn at Kulaniapia Falls, and access is restricted to the hotel’s guests (rooms from roughly $200). But you don’t have to stay overnight — day passes ($50 to $70 for adults, $30 to $50 for children 9 and under) grant access to the waterfall, where you can swim, paddle board or kayak.
Day passes also include discounts on group activities run by the hotel, including farm tours, cooking classes and even rappelling down the rock face alongside the waterfall.
