Pohoiki Hot Springs, also known as the geothermal tide pools at Isaac Hale Beach Park on the Big Island, are among Hawaii’s newest natural swimming spots. They were formed after the 2018 eruption of Kilauea, when lava entered the ocean and created a brand-new black sand beach along with a series of warm tide pools. The water usually stays between 89–100 °F (32–38 °C), as ocean water mixes with geothermal heat, making it noticeably warmer than the surrounding sea. Bathing here feels like a unique blend of hot spring and ocean pool. With the dramatic contrast of black lava shoreline and vivid blue water, this place is truly unforgettable.

What Should You Know Before Going to Pohoiki Hot Springs
Pohoiki Hot Springs are stunning, but keep in mind they are natural tide pools right by the ocean. These pools were created only recently and are not officially managed or supervised. The water temperature shifts with the tides and weather, often pleasantly warm (89–100 °F / 32–38 °C), but sometimes cooler when more seawater flows in.
Access to the pools is relatively easy, as they sit directly by the new black sand beach, but the surrounding lava rocks can be slippery and sharp – sturdy footwear is recommended. There are no changing rooms, showers, or restrooms on-site, so you’ll need to bring everything with you.
It’s also important to remember that tides can affect safety. During high surf or strong swell, the pools may become rough and dangerous. The safest time to enjoy Pohoiki is during calm seas and low tide. Entry is free, and no permits or reservations are required.
How to Get to Pohoiki Hot Springs
Pohoiki Hot Springs are located in Isaac Hale Beach Park on the southeastern coast of the Big Island, about a 55-minute drive from Hilo. The easiest route is via Highway 130, which ends right at the park. After the 2018 eruption, the area was closed for some time, but today it is fully accessible by car, with parking available on-site.
From the parking lot, it’s just a short walk across the new black sand beach created by lava. The path isn’t difficult, but expect uneven ground and some slippery rocks. Unlike many other Hawaiian natural pools, there’s no long hike required – the tide pools sit directly at the edge of the beach, only steps from the parking area.
Best Time to Visit Pohoiki Hot Springs
Pohoiki Hot Springs are technically accessible year-round, but the experience changes a lot depending on the season and weather. In summer, the ocean is usually calmer, and the pools fill with clean water that stays pleasantly warm around 89–100 °F (32–38 °C). This is the best time for a safe and relaxing soak.
In winter, however, larger waves and higher tides can flush colder seawater into the pools and sometimes make them unsafe. For this reason, it’s recommended to visit only when the ocean is calm and the weather is stable.
If you want to enjoy the place with fewer people, aim to arrive early in the morning or late in the afternoon. Midday tends to be busier, since Isaac Hale Beach Park is popular with both surfers and local families.

Pohoiki Hot Springs are located within Isaac Hale Beach Park, which is open to the public daily from 7:00 AM to 7:00 PM. Outside of these hours, the gate is closed, and access to the beach and tide pools is not possible.
Entry is free, and no permits or reservations are required. The only thing to keep in mind is that parking is limited, so it’s best to arrive either early in the morning or later in the afternoon when the lot is less crowded.
