Looking for a bite-sized adventure on the Big Island?

Wailuku River State Park is a gem right outside Hilo on the island of Hawaii. And this small park, sitting at only 16.3 acres, is a must-see if you’re in the area! The park is home to Hawaii’s largest river, the Wailuku River.

The river runs between the lava flows of Mauna Kea and the lava flows of Mauna Loa to the south. It’s a stunning river that spawns beautiful natural landscapes alongside it.

The park has two distinct and separate areas to visit.

Boiling Pots is a series of large pools connected by underground flow. The cascades roll and bubble as if boiling, giving Boiling Pots its name.

And don’t forget 80-foot Rainbow Falls.

Named for the rainbow that forms on misty mornings, legends say that the cave underneath the waterfall was the home of Hina, the mother of the demigod Maui. Come early morning and spot the rainbow for yourself. The hike to Rainbow falls is an easy .1 mile out and back trail.

Just two minutes from the start of the trailhead, it’s an easy stroll. For quiet times, head out early in the morning or later in the evening. Stay safe while you’re visiting and stay aware of flash floods. The area is popular for swimming and tubing, but the Wailuku River is responsible for 25 percent of the river drownings that occur in the state.  Open daily during daylight hours, this magical place is the perfect spot to visit with friends and family.

And with no entrance fee, there’s absolutely no reason not to visit! So pack your picnic and head to this tiny but mighty state park in Hawaii.
