Spouting Horn, Kauai, USA Hawaii, North America

Spouting Horn is a blowhole located on the south shore of Kauai, Hawaii, USA. It is a natural geological feature that ejects seawater into the air.

Visual Characteristics

The blowhole is a lava tube opening at sea level. When waves enter the tube, compressed air forces water upwards through the opening, creating a geyser-like spray. The surrounding area consists of dark, porous volcanic rock formations and sparse coastal vegetation.

Location & Access Logistics

Spouting Horn is situated approximately 3.2 kilometers (2 miles) west of Poipu. Access is via Lawai Road. Parking is available in a designated lot adjacent to the viewing area. No public transport directly serves the site; private vehicle or taxi is required.

Historical & Ecological Origin

This feature is a result of coastal erosion and the geological formation of lava tubes. The porous volcanic rock allows seawater to enter subterranean channels, leading to the pressurized expulsion of water at the surface.

Key Highlights & Activities

Observation of the blowhole's spray is the primary activity. The height of the spray varies with wave size, typically reaching 15-20 meters (50-60 feet) and occasionally higher. Visitors can also observe tide pools in the vicinity during low tide.

Infrastructure & Amenities

A paved viewing platform provides a vantage point. Restrooms are available at the parking area. Shade is limited. Cell phone signal (4G/5G) is generally available. No food vendors are present at the immediate site; facilities are located in nearby Poipu.

Best Time to Visit

The blowhole is active year-round. For optimal viewing of the spray height, visit during periods of larger ocean swells, typically in the winter months (November to March). Mid-morning to early afternoon offers direct sunlight on the spray, enhancing visibility.

Facts & Legends

Local legend states that a giant lizard named Puni once guarded this coastline. When challenged by a warrior, Puni was defeated and its tail was dragged along the shore, creating the lava tubes and the blowhole.
