Hawaiʻi Island's most dangerous beaches

County lifeguards and Fire Dept. rescue personnel make MORE rescues here than at any other beach in Kona. A powerful rip current ('the chute') runs north from the Kuʻemanu Heiau end along the rocks and out to sea; swimmers who fight it have drowned from exhaustion. Stay inside the reef-enclosed bay, keep clear of the north end, and obey lifeguard flags. Reef rock and surge can also injure entries/exits.

Severe seasonal shorebreak that dumps directly onto a steep sand face — neck, back and shoulder injuries are common (locally nicknamed 'Tragic Slams'), one of Hawaiʻi's worst beaches for spinal/neck injuries. Sand washes away entirely in winter swell (hence 'Magic'/'Disappearing' Sands). Powerful backwash and rip currents form fast; lifeguards report near-daily rescues even on calm summer days. Enter only on calm days, never turn your back on the waves, and obey the lifeguard.

Heavy seasonal shorebreak that turns punishing in winter, plus high surf and strong currents — official condition data flags heavy shore break, high surf and strong currents ('swim at your own risk'). In winter the sand strips away and the cove can be cut off; nearest fire/medical backup historically 15–20 min away. Lifeguard staffing is NOT confirmed on the current state list (see notes) — do not assume a guard is in the tower. Check flags/conditions and enter only on calm summer days.

Remote, unguarded white-sand beach reached only on foot (~20–30 min hike over lava) or rough 4WD. No lifeguard, no facilities, and nearest rescue is far away. Currents can be strong and surf rough, especially with winter swell; help is not close. Swim conservatively, never alone, and stay out when surf is up.

No lifeguard anywhere in Kekaha Kai State Park. Generally calmer than Kua Bay in summer, but shorebreak and currents pick up when surf is up, and rescue response is slow on this remote leeward coast. Watch conditions, stay close to shore, and stay out with winter swell.

No sand and NO lifeguard — entry/exit is off two lava ledges directly into deep water. When any surge or swell is running, the ledge entry becomes dangerous: surge can slam you onto the rock and exits can be impossible. Only experienced swimmers/snorkelers should enter, and only in calm morning conditions. Time exits between sets; sea urchins lurk in the ledge holes.

No lifeguard anywhere in Kekaha Kai State Park. Remote leeward shoreline with white and salt-and-pepper sand; shorebreak and currents strengthen with surf and rescue is slow. Stay close to shore and respect winter swell. NOTE: this is a duplicate/umbrella entry that geographically overlaps the Mahaiʻula and Makalawena records.

No lifeguard, remote, and no cell service — emergency help is far away. Freshwater springs make the water cold and murky, and tiger sharks are documented near the river/spring mouths where visibility is low; open-bay currents add risk. The calm brackish lagoon is the safest swim; do not swim in the murky open bay, and never alone.

Powerful shorebreak and strong year-round rip currents on an exposed, unsheltered black-sand beach at the bottom of a steep cliff trail. No lifeguard, 30+ minute emergency response, and multiple documented drownings; even local residents and rescue divers do not enter the water here. Hike in for the views — do not swim.

Premier Hilo surf break, not a swimming beach. Rocky bottom, common rip currents, and a river mouth whose flow can surge without warning. The nearshore bottom drops off fast and shorebreak pounds the rivermouth cobble. Lifeguarded during the day, but enter the water only if you surf at a local-equivalent level.

Brand-new (2018 lava) black-sand beach with a dangerous shorebreak and strong currents along the sand. Lava boulders make ocean entry hard even on calm days. This is NOT a swimming beach. Lifeguard coverage is not on the official State list and any tower is staffed only seasonally — do not rely on a guard being present. The DOH also warns against entering the warm geothermal ponds with any open wound (bacterial-infection risk).

Fully exposed to open-ocean swell with a brutal shorebreak and rip currents/undertow that have caused MULTIPLE drownings (documented deaths 2017, 2019, 2022, 2024). No lifeguard, limited cell service, and a steep cliff trail that makes rescue slow — bystanders have been unable to reach victims. Enter only in genuinely calm conditions, never alone; safest treated as look-don't-touch.

Despite a lifeguard tower at the park, the water here is hazardous: a strong rip runs out the boat channel/ramp on the north/northeast side, cold offshore freshwater springs cause sudden temperature shock, and high surf is common. A swimmer drowned here (Puna man, Sept 2014). Most visitors come to photograph turtles, not swim. Check with lifeguards and the flag before any water entry; do not swim near the boat ramp.

Remote olivine-sand cove inside a collapsed cinder cone with no lifeguard, no shade, and no rescue. The bay opens to the open South-Point swell window; strong wrap-around currents are hard to spot, waves can break directly onto the steep cobble shore, and the only exit is a ~2.5-mi cliff-edge hike. Visitor drowning/distress reports exist. Treat as a viewpoint, not a swim beach — if you enter at all, only on a genuinely flat day, never alone, and stay close to shore.

The southernmost point of the USA — lava cliffs over deep open ocean, NOT a swimming beach. The powerful converging 'Halaea Current' sweeps straight out to sea with nothing to stop you. Cliff-jumping from the old wooden platforms has repeatedly killed and badly injured people — at least four deaths in the six years to 2024 plus a Dec 2025 visitor fatality. If a current takes you, rescue is unlikely. Do not jump and do not enter the water.

Very remote, road-less bay reached only by a long, rough 4WD track (sources describe up to ~6.5 mi one way). No lifeguard, no reliable cell coverage, no facilities, and no help if anything goes wrong. Rocky entry and exposed currents; a Nāʻālehu man drowned here in Dec 2014. Treat any water entry as fully self-rescue.

A rocky lava shoreline on Honuʻapo Bay, NOT a sand swimming beach, with no lifeguard. Rough surf, strong currents, and rocks make the open shoreline dangerous for swimming; surge can sweep the rocks and tidepools. Stay to the sheltered tidepools/old fishponds and treat the open water as a no-swim zone.

A restored fishpond/wetland estuary preserve on Honuʻapo Bay with a rocky shoreline and no lifeguard — for coastal walking and birding, not swimming. Ocean surge and currents along the rocks, combined with stream/estuary mixing, make water entry hazardous. Explore on foot; do not swim.
