Peepee Falls - Deep Research Report

Deep Research Report

Last updated: April 23, 2026

What it is

Peepee Falls, also known as Pe'epe'e Falls (pronounced "Peh-eh-peh-eh"), is a series of waterfalls located on the Wailuku River in Wailuku River State Park, near Hilo on the Big Island of Hawaii. It is situated about 1 to 1.5 miles upstream from the more famous Rainbow Falls. The falls cascade into an area known as the "Boiling Pots," a series of terraced pools and cascades where the river's turbulent flow over lava rocks creates the illusion of boiling water. The tallest of the falls is estimated to be between 50 and 80 feet. The surrounding area features lush vegetation and ancient lava rock formations.

Visitor experience

Visitors come to Peepee Falls and the Boiling Pots to observe the unique geological features and the beauty of the Wailuku River. The primary viewing experience is from a public lookout platform within Wailuku River State Park. From this overlook, visitors can see the Boiling Pots churning below, a phenomenon especially dramatic after heavy rainfall, as well as a more distant view of Peepee Falls upstream. The site is ideal for those interested in scenic natural spots and photography. Historically, some visitors attempted to get closer to the falls or swim in the pools; however, doing so is now explicitly prohibited by closure signs, and violations may result in fines.

Logistics

  • Area: Peepee Falls is part of Wailuku River State Park, located just west of downtown Hilo on the Big Island.
  • Access: To reach Peepee Falls, drive inland on Waianuenue Avenue from downtown Hilo, following signs toward Rainbow Falls. Continue approximately one mile past Rainbow Falls, then turn right onto Pe'epe'e Falls Road, which leads to a parking lot.
  • Reservations: No reservations are required.
  • Timing: Wailuku River State Park is generally open from sunrise to sunset, with some sources specifying hours between 8:00 AM and 6:00 PM. Visiting in the early morning can offer a more peaceful experience with fewer crowds.
  • Parking: A paved parking area is available at the viewing point for Peepee Falls and the Boiling Pots.
  • Permits: No permits are needed to visit.
  • Likely duration: This is typically a quick stop, taking about 15-30 minutes to view the falls and Boiling Pots from the designated platform. It functions best as a brief stop or one component of a half-day tour of Hilo's waterfalls.
  • Facilities: Restrooms are available at the park's viewing area.

Safety and cautions

  • Swimming: Swimming in the Wailuku River at Peepee Falls or the Boiling Pots is strongly discouraged and dangerous due to powerful currents, unpredictable water conditions, and a history of drowning incidents.
  • Access beyond overlook: Approaching the falls directly or descending to the river's edge is now prohibited. Signs explicitly warn against proceeding beyond designated viewing areas, and individuals ignoring these warnings may face fines or citations. Unofficial trails that once existed are unmaintained, steep, slippery, and treacherous.
  • Flash Floods: The Wailuku River is susceptible to sudden flash floods, especially during or after heavy rainfall. River conditions can change rapidly and become extremely dangerous, sometimes leading to park closures.
  • Slippery Surfaces: All rocks and pathways near the water can be extremely slippery due to mist and moisture.
  • Mosquitoes: Mosquitoes are often prevalent in this lush, wet environment; insect repellent is highly recommended.

Editorial take

Peepee Falls is a worthwhile stop for travelers already in the Hilo area, particularly those who appreciate natural scenery and want to experience the unique "Boiling Pots" phenomenon. It's best suited for visitors looking for a quick, accessible natural attraction and those who enjoy a less crowded waterfall viewing experience compared to Rainbow Falls. It should be prioritized by individuals integrating it into a broader Hilo itinerary that includes other nearby natural sights.

Travelers seeking an immersive hiking or swimming experience should skip Peepee Falls due to the official prohibitions and significant safety concerns. Those with limited time who can only visit one waterfall may find Rainbow Falls or 'Akaka Falls (another prominent Big Island waterfall) to offer more visually striking and easily accessible close-up views.

Peepee Falls should not be confused with Rainbow Falls (Waiānuenue), which is a separate, larger waterfall further downstream in the same park, famous for its morning rainbows. While the Boiling Pots are directly associated with Peepee Falls, they refer to the turbulent pools themselves, not the falls. Wai'ale Falls is another distinct, less-visited waterfall also found upstream on the Wailuku River.
