About Princeville
Princeville occupies a dramatic bluff on Kauaʻi's North Shore, overlooking Hanalei Bay and the jagged ridgeline of Nāmolokama Mountain. Originally a sugar plantation named after a Hawaiian prince, the area is now a planned resort community with golf courses, condos, and the 1 Hotel Hanalei Bay perched on the cliff's edge. The North Shore receives the most rainfall on the island, which keeps everything impossibly green but also means streams run heavy after storms — something to watch when checking water quality at nearby beaches.
Nearby Beaches — Ranked by Proximity
Queen's Bath
DANGEROUS ●
A natural lava-rock pool at the base of the Princeville cliffs, Queen's Bath has claimed multiple lives from rogue waves that sweep across the ledge without warning. The hike down is steep, muddy, and treacherous when wet. Even experienced ocean swimmers have been caught off guard here, and rescue access is extremely limited.

Hideaways Beach
Low ●
Also called Pali Ke Kua, this small crescent of sand sits below the 1 Hotel Hanalei Bay and requires a steep scramble down a root-covered trail. The reward is a relatively uncrowded beach with decent snorkeling along the reef to the left. Summer months offer the calmest conditions — winter swells can make the water rough and entry difficult.

Below 1 Hotel
One of the most photographed bays in Hawaii, Hanalei stretches nearly two miles in a crescent framed by emerald mountains. The bay has been on the state's impaired waters list since 2004 due to runoff from the Hanalei River, so bacteria levels tend to spike after rain. On calm summer days, the eastern end near the pier offers mellow swimming and stand-up paddling.
Protected by one of the longest fringing reefs in Hawaii, Anini stays calm when other North Shore beaches are pounded by surf. The shallow lagoon is ideal for beginner snorkelers, and the long grassy park behind the beach has camping spots and picnic pavilions. Water quality here consistently tests well thanks to distance from major stream outlets.
Named for the lava-tube formations in its outer reef, Tunnels (Makua) is widely considered the best snorkeling spot on Kauaʻi. The inner reef creates a calm lagoon teeming with tropical fish and sea turtles during summer months. Winter brings powerful North Shore surf that makes swimming here extremely hazardous — check conditions before going.
Getting Around
Princeville sits at the end of Kuhio Highway (Route 560) on Kauaʻi's North Shore. Beyond Princeville, the road continues through Hanalei and dead-ends near Kēʻē Beach at the start of the Nā Pali Coast. There is only one road in and out, so traffic can be slow during peak hours.
- Rental car: Essential for beach-hopping on the North Shore — distances are short but there is no practical alternative for reaching Tunnels or Anini
- Hāʻena shuttle: During peak season, a mandatory shuttle system operates for access beyond Hanalei — private cars may be restricted past the Hanalei Bridge
- Parking: Hideaways trailhead parking is extremely limited (3-4 spots near the 1 Hotel entrance) — arrive early or walk from Princeville Center
- Tip: The one-lane bridges between Princeville and Hanalei alternate traffic — yield to oncoming cars and expect delays during busy afternoons
If Brown Water Is Active
After heavy rain, bacteria levels spike at beaches near streams and river mouths. If a brown water advisory is active near Princeville, Kauaʻi:
- Wait 72 hours after rain stops before entering the water
- Avoid brown or murky water regardless of whether an advisory is posted
- Best rain-resistant option: Tunnels Beach (West past Hanalei) — generally clearer after rain due to geography
- Check the Kauaʻi live advisories page for current conditions
