About Wailua River State Park
Aloha! Wailua River State Park ranks among Kauai's most visited destinations and costs nothing to enter. This East Side location centers around Hawaii's only navigable river, where you can kayak through tropical landscapes to discover waterfalls and ancient Hawaiian sacred sites.
The park offers diverse activities for different experience levels. Paddle upstream to the Fern Grotto, a natural lava rock amphitheater draped in tropical ferns, or hike trails that wind through rainforest. Photography enthusiasts will find plenty of opportunities among waterfalls and valleys.
Arrive early, especially on weekends, as parking fills up quickly. The best kayaking conditions are typically in the morning when winds are calmer. Several local outfitters near the park entrance offer rentals and guided tours – experienced paddlers can launch from the boat ramp.
The park stays open until 9 PM on weekdays and 7 PM on weekends. Bring waterproof gear for your camera and comfortable hiking shoes if you plan to explore the trails. This area was once the center of ancient Hawaiian royalty, so you're walking through centuries of cultural history surrounded by Kauai's natural landscape.
