The Hilo side of the Big Island is blessed with abundant rainfall, which means waterfalls, rivers, and natural swimming holes around almost every corner. Here are some of our favorite spots to cool off—from easy-access pools to hidden gems that take a little more effort to find.
⚠️ Important Safety Notice
Rivers and streams along the Hamakua Coast are prone to flash flooding. Never swim if water is surging, murky, or if rain is falling upstream. Conditions can change in minutes. When in doubt, stay out.
Swimming Holes to Explore
Wai'ale Falls
10 minutes from Island Goodes
An easy-to-find swimming hole upstream from Rainbow Falls. The short trail leads to a pool with a small waterfall—perfect for a quick dip. It feels rural and secluded despite being close to Hilo.
Waikaumalo Park
15 minutes north of Hilo (Old Mamalahoa Hwy)
A local favorite that doesn't appear in most guidebooks. Deep pools perfect for jumping, surrounded by lush vegetation. The water is cool and refreshing—exactly what you need on a humid Hilo day.
6 Tons Swimming Hole
Old Mamalahoa Highway at Kawainui Stream
Named for the old weight limit on the bridge, this spot features a small waterfall cascading into a refreshing pool. It's right off the scenic Old Mamalahoa Highway, making it easy to combine with a drive up the Hamakua Coast.
Umauma Falls
16 miles north of Hilo
Three-tiered waterfall on private property with swimming, kayaking, and zipline options. The $10 access fee includes beautiful gardens and multiple viewpoints. A great half-day adventure.
Where NOT to Swim
Rainbow Falls
Viewing only! Despite its beauty, the currents below Rainbow Falls are treacherous. This is a photography spot, not a swimming hole.
Boiling Pots (Pe'epe'e Falls)
Absolutely no swimming. Multiple drownings have occurred here due to deceptive currents and underwater caves. Viewing only from the overlook.
What to Bring
- Water shoes - rocks can be slippery
- Towel and change of clothes
- Reef-safe sunscreen
- Drinking water and snacks
- Waterproof bag for valuables
- Bug spray for trailside spots
Best Time to Visit
Morning is generally best—calmer water, fewer people, and you can check conditions before committing. After heavy rain, wait at least 24 hours before swimming in any river or stream. The water needs time to clear and levels need to drop.
